Full textAbstract:
Eggplant is a very important vegetable and economic resource crop for populations in urban areas of developing countries. Its cultivation, on acidic coastal soils of Côte d’Ivoire, presents several edaphic constraints. This study aims to assess the effects of organic fertilizers and an organo-mineral fertilizer, as compared to mineral fertilizers, on the growth and eggplant yield on an acid soil. The experiment was carried out in a randomized Fisher block, with 4 treatments and a control repeated 3 times. Treatments consisted of organic and organo-mineral fertilizers, a liquid organic fertilizer and a mineral fertilizer application. Application rates of organic and organo-mineral fertilizers were 17.5 t ha-1. The liquid organic fertilizer rate was 1 L per 200 L ha-1 of water. As for the mineral fertilizer, the formula 0-23-19 and urea (46-0-0) were used, bringing rates of 138 kg ha-1 (N), 65.35 kg ha-1 (P2O5) and 54 kg ha-1 (K2O). The organo-mineral fertilizer used produced the best effects. Very highly significant (p < 0.001) growth, such as plant height and collar diameter, were 52.69 and 1.49 cm, respectively, 90 days after transplanting. Concerning yield, statistical analysis showed highly significant differences (p < 0.01) between treatments. The highest fruit yield (20.87 t ha-1) was recorded in mineral fertilizer plot, but not significantly different from those of plots with organo-mineral (17.55 t ha-1) and organic (16.66 t ha-1) fertilizers. Organo-mineral fertilizers, based on highly enriching organic materials, are capable to contribute to a lasting improvement in the practice of this crop.

Greenhouse, field and laboratory studies were conducted to determine if N availability to corn (Zea mays L.) and NO3 leaching were affected by encapsulating conventional granular fertilizer within peat pellets (organo-mineral fertilizers or OMF). In the greenhouse, total N uptake by three 6-wk crops of corn from soil fertilized with NH4NO3 was 9.1% higher than the mean from soils fertilized with OMF made with urea (OMF-urea) or with NH4NO3 (OMF-AN). Total N uptake was 5.1% higher from soils fertilized with OMF-AN than OMF-urea. Differences in total N uptake among the fertilizers were constant across crops. In two field trials, total N uptake was slightly higher (4%) from soil fertilized with commercial NH4NO3 than with OMF-AN. In a laboratory experiment, NO3 from commercial NH4NO3 fertilizer leached more readily from soil than NO3 from OMF-AN. Approximately 95% of the NO3 from commercial NH4NO3 fertilizer leached from 3-cm soil cores in the first 50 mL of leachate whereas only 26% of the NO3 contained in OMF-AN leached. In another trial, NO3 from commercial NH4NO3 fertilizer leached more deeply than NO3 from OMF-AN after application of 2.5 cm irrigation water to soil in 63-cm leaching columns. Virtually no NO3 was retained within the OMF-AN pellet after leaching, suggesting that the retention of NO3 by OMF-AN used in our work is of limited duration. The OMF is an effective source of N to crops and is less prone to NO3 leaching losses than commercial NH4NO3 fertilizer when rain occurs soon after application. More work is required to determine the effect of pellet size and composition on NO3 retention, NO3 leaching losses and crop availability of N. Key words: Nitrate leaching, corn, organo-mineral fertilizers

ABSTRACT The aim of this study was to evaluate P availability, P and C contained in the microbial biomass, and enzymatic activity (acid phosphatases and β-glucosidases) in a Nitisol with the application of mineral and organo-mineral fertilizers. The experiment was performed in a protected environment with control over air temperature and soil moisture. The experimental design was organized in a "5 x 4" factorial arrangement with five sources of P and four times of soil incubation. The sources were: control (without P), triple superphosphate, diammonium phosphate, natural Arad reactive rock phosphate, and organo-mineral fertilizer. The experimental units consisted of PVC columns filled with agricultural soil. The columns were incubated and broken down for analysis at 1, 20, 40, and 60 days after application of the fertilizers. In each column, samples were taken at the layers of 0-2.5, 2.5-5.0, and 5.0-15.0 cm below the zone of the fertilizers. The application of soluble phosphates and organo-mineral fertilizer temporarily increased P availability in the zone near the fertilizers (0-2.5 cm), with maximum availability occurring at approximately 32 days. Microbial immobilization showed behavior similar to P availability, and the greatest immobilizations occurred at approximately 30 days. The organo-mineral fertilizer was not different from soluble phosphates.

The results of investigations of the influence of the long application of systems of main soil and fertilizer treatment on the quantitative indices of the weed component of soybean agrocenosis are described. The research was conducted in the four-field crop rotation of stationary experience in 2009-2016.
It was found that the unploded system of main treatment compared with the plow, led to an increase in the number of weeds by 89% in mineral fertilizers and 104% in the organo-mineral. Vegetative crude mass of weeds on unplugged systems increased, comparatively with plow, on the background of mineral fertilizers by 46% and 44% on organo-mineral. Against the background of mineral fertilizers, the total number of weeds was less than in the organomineral at 36%, vegetative crude mass - less by 18%. In non-branch systems, the number of species increased in comparison with the plow by 20% against the background of minerals and by 18% against the background of organo-mineral fertilizers.
On both fertilizer backgrounds, there is a steady increase in the number of mature and wintering species in non-seeded systems. The most common species of weed - bluish weed - 49% of the total weed in the background of mineral fertilizers and 45% on the background of organomineral. In total 13 species of weed have been detected in agrocenosis.
The most favorable for soya phytosanitary state of crops, both in the background of mineral and organo-mineral fertilizers, was created under the plow system of the main soil cultivation, which included discarding the stubble of the predecessor on 10-12 sm immediately afterwards at abrupt rumbling and sputum at 25-27 sm in 10-12 days.

Organo-mineral fertilizers are an opportunity for technological innovation, because allow the correct disposal of waste from various agroindustrial sectors, which is a global problem, in order to add value to the by-product generated, as prioritized in reverse logistics. In this sense, the objective of this work was to evaluate the effect of organic matter sources on the composition of organo-mineral fertilizers in relation to the exclusive use of mineral fertilizers in cultivation of grain sorghum. The experiment was carried out at the Experimental Farm of the Federal Institute of the Triângulo Mineiro, located in the municipality of Campina Verde, State of Minas Gerais, Brazil. The experimental design was a randomized block with eight treatments and four replications arranged in a 4 × 2 + 2 factorial scheme, corresponding to: four levels of organo-mineral fertilizers (70, 100, 130 and 160% of the recommended dose of phosphorus), two sources of organo-mineral fertilizers (sewage sludge and filter cake), and two controls (without and with recommended mineral fertilization). The evaluations were: height of stem, number of leaves and stem diameter at 30, 60, and 90 days after sowing (DAS); total plant height; dry mass of plant shoot at 90 DAS, in vitro digestibility of organic matter at 90 DAS; the relationship of leaf area/ leaf and leaf area/ plant at 90 DAS. All parameters obtained a significant effect for the levels of organo-mineral fertilizer, independent of organic source, except to number of leaves and stem diameter. However, the relationship between the two organic sources was not significant just to plant height at 60 DAS. Interaction between fertilizer levels and organic source occurred to plant height at 90 DAS, dry mass per plant at 90 DAS and in vitro digestibility of organic matter. There was good adjustment in the quadratic regression equation for sorghum growth.

The study deals with organic, mineral and organo-mineral systems of winter wheat fertilization in the conditions of the Volga forest-steppe. According to the organic fertilization system, straw of the predecessor, green manure and Biocomposite-correct were introduced into the soil (typical medium-thick medium loamy chernozem) for green manure mass (vetch-oat mixture). The organo-mineral system included two options: straw applied together with nitrogen in a dose of 10 kg per 1 ton of straw and zeolite enriched with amino acids. The mineral fertilizers were nitrogene phosphorus with the NPK content of 16 kg ai/ha, carbamide and potassium chloride. In addition, highly siliceous rock zeolite was applied as a fertilizer. It was found that the use of organic and organomineral fertilizers improves the nutrient regime of the soil; in terms of the content of nitrogen, phosphorus and potassium in the arable layer, these options were not inferior to the option with the use of mineral fertilizers. When introducing zeolite enriched with amino acids, the yield of winter wheat exceeded the option with the use of mineral fertilizers by 0.59 t/ha. The use of organic and organo-mineral fertilizers contributes to the production of environmentally friendly products

Full textAbstract:
The crucial trend in the intensification of gardening is the use of agrochemicals, including the systematic application of mineral fertilizers, regulated by the production flow chart of fruit products. Technological pressure on the soil causes aggravating the ecological problem of loss of the fertility level in the conditions of the orchard monoculture. The search for sustainable and environmentally effective approaches to solving the problem of managing fertility factors is aimed at studying the effects of biological and biomodified fertilizers. The changes in the main indicators of the effective fertility of the structural-metamorphic agrosem in the conditions of the orchard monoculture with the application of biomodified organo-mineral fertilizer were studied in dynamics. The prolonged effect of organo-mineral fertilizer on increasing the content of the main indicators of effective fertility in the soil was determined six years after application. The use of biomodified organo-mineral fertilizer in the orchard fertilization system is considered as an element of an integrated strategy for the management of orchard soil fertility.

ABSTRACT Brazil is dependent on importation of fertilizers, especially the potassics. Rocks and minerals that contain nutrients have a potential for use in agriculture as fertilizer, especially those of slow solubilization and that exhibit residual effect. In this context, the objective was to assess the feasibility of glauconite rock as potassium source for the cultivation of ornamental sunflower. The experiment was conducted under controlled conditions arranged in an entirely randomized design, in a 4x4 + 4 factorial scheme, with four replicates and one plant per plot. Four glauconite-based fertilizers were used as a potassium source: fine grained glauconite, fine grained organo-mineral glauconite, coarse grained glauconite and coarse grained organo-mineral glauconite, in four doses, as well as an additional treatment with four doses of KCl, the principal conventional source of the nutrient. The height of the flower stalks, the diameter of the stem and floral capitulum, the number of cultivation days and post-harvest durability were evaluated. The application of KCl yielded the production of flower stems with greater height and larger capitulum diameter in relation to the supply of glauconite. Among the glauconite based fertilizers, the fine grained organo-mineral product provided the best flower charateristics. The postharvest commercial durability of the flower stalks was higher in plants that received the glauconite and fine grained organo-mineral glauconite. The fine grained organo-mineral glauconite surpasses all other alternative sources of potassium in relation to the agronomic characteristics evaluated.

The article presents the results of research on the systematic application of organic and mineral fertilizers as the indicators of fertility of gray forest soil and the formation of corn yield per grain. It was determined that in the five-field field crop rotation during the cultivation of the crop, soil backgrounds with different physical and chemical properties were formed. Application of litter manure (direct action) at a dose of 60 t / ha on the background of moderate rates of fertilizers (N40-80R30-60K40-80) contributed to the neutralization of the soil solution to the values of slightly acidic reaction (pH sol. - 5.2-5.3 units), whereas in the absence of manure (mineral fertilizer system) the pH of the salt remained within the medium acid reaction. The most effective in terms of humus condition of the soil was the organo-mineral fertilizer system (12 t / ha of manure + N80P60K80) and organic (12 t / ha of manure per 1 ha of crop rotation area), respectively, the content of total humus was - 1.35 and 1.37% or in percentage terms by 25-27% higher compared to the control (without fertilizers) - 1.08 t / ha. Optimization of nutrient regime (hydrolyzed nitrogen, mobile forms of phosphorus and potassium) of the soil at the end of rotation was provided by the organo-mineral fertilizer system (N100P60K100 against the background of 60 t / ha of manure). The highest productivity of corn for grain (9.49 t / ha) was provided by the organo-mineral fertilizer system (60 t / ha of manure + N100P60K100), which is 86% higher than the control (without fertilizers), under these conditions the largest collection of crude protein was obtained – 0, 98 t / ha.

Influence of prolonged application of various fertilizer systems and periodic liming on the dynamics of redox potential (ROP) of light grey forest surface-gleyed soils under different crop rotations is presented in the research results. The obtained ROP indexes showed significant variability in variants of experiment depending on the fertilizer, lime and terms of determination in both fields of winter wheat and spring barley. The highest ROP values in variants with organo-mineral and mineral fertilizer systems with background of liming were observed in spring. They decreased during the period of maximum growth and development of winter wheat and spring barley together with the growth of microbiological activity and the intensity of CO2 release, and slightly increased before harvesting. It was established that the application of organo-mineral and mineral fertilizer systems with the background of liming with CaCO3 dose, calculated according to hydrolytic acidity, to the greatest extent increase ROP, especially during the period of intensive growth and development of plants. Compared to similar fertilizer system with the background of liming with a CaCO3 dose, calculated according to the pH- buffer capacity, it contributes to one-sided growth of oxidation processes and additional mineralization of humus. Thus, the organo-mineral fertilizer system with the application of 10 tons of manure per hectare of crop rotation and one norm of mineral fertilizers (N65P68K68) with the background of liming with CaCO3 dose, calculated according to the pH-buffer capacity (2.5 t/ha), contributes to rational use, preservation and fertility protection of light grey forest surface-gleyed soils, optimizing the redox potential during whole growing season of crops, and provides high yields. Studies have shown that during whole growing season of winter wheat and spring barley the lowest values of oxidation were obtained with the long-term use (for 50 years) of mineral fertilizer system with the introduction of one norm of mineral fertilizers only. It led to a decrease in the actual soil acidity to 4,03 pHKCl units and the increase of hydrolytic acidity to 5.11 mg-eq/100 g of soil. This once again emphasizes the importance of periodic liming of acid light grey forest surface-gleyed soils as a factor weakening the negative influence of mineral fertilizers. Key words: light grey forest surface-gleyed soils, redox potential, mineral fertilizers, manure, lime.

The article presents the results of research on the biological activity of gray forest soil depending on the systematic use of organic and mineral fertilizers. It is established that effective reproduction of humus in gray forest soil is provided by organo-mineral (12 t of manure together with N80P60K80 application per 1 ha of crop rotation area) and organic (24 t/ha of manure), respectively 36,5 t/ha, and 35,6 t/ha. The application of only mineral fertilizers in the norm of N80P60K80 per 1 ha of crop rotation area resulted in a decrease in humus reserves by 9 % relative to the initial level (32,4 t/ha). The highest degree of humification of organic matter provided the option of applying organic fertilizers (60 t/ha) both separately – 36,0% and compatible with mineral – (60 t/ha manure + N80P60K80) – 34 %. Prolonged use of organic and mineral fertilizers in crop rotation significantly increased the total number of microorganisms in the soil. The result was increased decomposition of organic matter and increased release of CO2 from the soil. The areas with the highest biological activity and CO2 intensity were characterized by areas where the soil was systematically enriched with fresh organic matter. The intensity of biological processes in the organo-mineral system increased by 67 % relative to the variant without fertilizers and by 30 % relative to the variant with only N80P60K80. The use of organic and mineral fertilizers in one system stimulated the process of decomposition of fiber – at the level of 78,5 %, which in percentage terms exceeded the value of the indicators obtained for a purely mineral fertilizer system.

This study was conducted to determine the effects of use organo-mineral fertilizers and poultry manure on yield and quality of seed tubers different potatoes varieties (Solanum tuberosum L.). The study was designed in three replicated completely randomized block factorial design with eight potato cultivars (Madaline, Provento, Marfona, Agata, Arizona, Mustang, Rumba and Saviola) and including three different fertilizer as Hexaferm organo-mineral (%20 organics, 8-21-0+Zn), compost (1 t da-1) and fermented poultry manure (1 t da-1). In order to determine the effect of fertilizer forms on the yield and quality characteristics of different varieties of potatoes were examined features like output time of the tuber, output rates, plant height, stem number per hill, tuber yield per hill, total tuber yield, cracks tuber yield, dry matter content, starch content and specific gravity. Used fertilizers have no significant effect on output time of the tuber, output rates, plant height, stem number per hill, total tuber yield, dry matter content, starch content and specific gravity of varieties. The difference observed in terms of output time of the tuber, output rates, plant height, stem number per hill between the varieties was insignificant. The difference between the average tuber yield per hill, total tuber yield, cracks tuber yield, dry matter content, starch content and specific gravity of varieties were significant. Similarly, the fertilizers had a significant effect on the average tuber yield per hill of varieties . The significant interactions were found on traits average tuber yield per hill and average specific gravity between Fertilizer x Varieties. As a result, considered economically the fermented and compost poultry manure can be used instead of organo-mineral fertilizers in the production of seed potatoes.

One from actual problems of ecological safety of the modern industrial cities development is utilization of sewage. One of solutions of this problem is studying of possibility of use of ecologically safe organo-mineral fertilizers on the basis of a precipitation of city sewage. Therefore studying of influence of organo-mineral fertilizers on the basis of a precipitation of sewage (Dnipropetrovsk) in comparison with complex fertilizer ammophos on the number and specific structure of soil micromycetes was the purpose of researches. Field experiments were made on sites of 5 m2 in the following variants: control without fertilizers; introduction of ammophos and organo-mineral fertilizers on the basis of a precipitation of city sewage in number of 10 and 30 t/hectare. Experiments were made in triple frequency on fields of Erastovsky experimental station of Institute of agriculture of steppe zone NAAS of Ukraine (Pyatikhatsky area, Dnipropetrovsk region). The soil (chernozem usual) selected from depth of 0–10, 10–20 and 20–30 cm under crops of summer barley of a sort «Galaxies» in a phase of full maturing of seeds. Quantity of soil micromycetes considered on Capek agarized medium. Structure of soil microscopic fungi cenosis estimated using indicators of frequency of species occurrence, similarity of communities (Serensen coefficient), extents of species domination in cenosis (Berger-Parker index), specific wealth (Simson index) and a specific variety (Shannon index). In a layer of soil 0–10 cm of a site at introduction of 30 t/hectare of organo-mineral fertilizers on the basis of a precipitation of city sewage the quantity of microscopic fungi increased by 1.5 times in comparison with control. In the bottom layers (10–20 and 20-30 cm) – in 1.3 and 1.6 times –espectively. The increase in quantity of micromycetes is noted and in the soil of sites after introduction of 30 t/hectare of ammophos. In a layer of soil 0–10 cm their number increased by 2.3 times, and in the bottom layers – in 1.9 and 2.1 times respectively in comparison with control. From soils of a site of a field experiment are allocated and identified 13 species from 10 genuses of microscopic fungi. Soils of sites of various variants of experience differed on the frequency of occurrence of microscopic fungi. From the chernozem usual of control site are allocated 4 species of micromycetes. In micocenosis dominated Fusarium oxysporum with a frequency of occurrence 100 %, to subdominant species (frequency of occurrence 40 %) belonged F. solani. The least similar on the control was micocenosis of site at introduction of 30 t/hectare of ammophos. Micocenosis of soils in variants of experience at introduction of ammophos in number of 10 t/hectare and organo-mineral fertilizers from a precipitation of city sewage in number of 30 t/hectare were very close to control variant. In the soil of site at introduction of organo-mineral fertilizers from a precipitation of city sewage in number of 30 t/hectare 6 species of microscopic fungi are identified. In micocenosis dominated P. vinaceum (frequency of occurrence 80 %), Trichoderma viride (frequency of occurrence 40 %) belonged to subdominants. On the basis of determination of micromycetes frequency of occurrence, coefficient similarities of communities, indexes of domination, specific wealth and variety, it is proved that entering into the soil of organo-mineral fertilizers on the basis of a precipitation of sewage promotes to increase of specific variety of microscopic fungi. It is shown that use of organo-mineral fertilizers on the basis of a precipitation of sewage considerably reduces the frequency of occurrence of a phytopathogenic specie Fusarium oxysporum which is the activator of root decay at plants.

The production of organic mineral fertilizers enriched with natural phosphates may increase the solubility of phosphorus, minimizing the dependence of acidulated phosphate fertilizers. In view of the above, the objective was to evaluate the bioavailability of nutrients due to the incorporation of phosphate sources through vermicomposting and composting. It was used a completely randomized design in a 4 x 3 factorial design, with five replicates and four sources of P (1 - Ammonium single superphosphate, 2 - Itafós phosphate, 3 - Araxá phosphate and 4 - termophosphate) and three methods of phosphorus sources addition in the production of organo-mineral fertilizer process: 1 - Vermicompost produced adding the P sources at the beginning of the vermicomposting process (VPB), 2 - Vermicompost produced adding the P sources at the end of the vermicomposting process (VPE) and 3 - Compound, non-vermicomposting, produced with addition of the P sources at the beginning of the composting process (CP). The addition of Araxá or Itafós natural phosphate in composting or after vermicomposting process leads to the production of an organo-mineral fertilizer with good availability of nutrients, such as calcium and phosphorus.

ABSTRACT The use of organo-mineral fertilizer is an alternative measure to mitigate salt stress in semiarid regions. Thus, the objective of this work was to evaluate the physiological indexes of peanut crops under irrigations with fresh and brackish waters and applications of organo-mineral fertilizers. The experiment was conducted from June to September, 2019, at the Universidade da Integração Internacional da Lusofonia Afro-Brasileira (UNILAB), in Redenção, state of Ceará, Brazil, using a completely randomized experimental design in a 5 × 2 factorial arrangement, with four replications. The treatments consisted of five soil fertilizers (F1= 100% NPK mineral fertilizer at the recommended rate; F2= 100% bovine manure-based biofertilizer; F3= 100% plant ash; F4= 50% mineral fertilizer and 50% bovine manure-based biofertilizer; and F5= 50% mineral fertilizer and 50% plant ash); and two salinity levels (electrical conductivities) of the irrigation water (1.0 and 5.0 dS m-1). Photosynthetic rate, transpiration, stomatal conductance, leaf temperature, internal CO2 concentration, water use efficiency, and chlorophyll index of the plants were evaluated at 40 and 54 days after sowing (DAS). Plants irrigated with fresh water presented higher stomatal conductance, photosynthetic rate, and transpiration, regardless of the fertilizer used. The use of 100% bovine manure-based biofertilizer resulted in decreases in salt stress and increases in water use efficiency at 40 DAS, and decreases in leaf temperature and increases in relative chlorophyll content at 54 DAS.

Ginger, Zingiber officinale is one of the most cultivated spices in the world. Therefore its production is often subject to high pest and disease pressures, particularly that of plant parasitic nematodes. For the sustainable management of parasitic nematodes of ginger, a trial was conducted at Agronomic Research Station of the Graduate School of Agronomy at the University of Lomé to assess the efficacy of some organo-mineral fertilizers on parasitic nematodes. An organic manure based on house waste valorization in three doses (0tha -1 ; 15tha-1 and 25tha-1 ) and five mineral fertilizer formulations from simple mineral fertilizers (Urea 46%, the chloride of potassium and the triple superphosphate): N0P0K0; N45P15K60; N70P50K50; N90P30K100 and N125P90K100) were used according to a split plot design. The inventory of the nematodes permitted to count five genders of nematodes: Meloidogyne; Xiphinema; Longidorus; Helicotylenchus and Pratylenchus. The results indicated that an input of 25 tons of organic manure associated with mineral fertilizer of N70P50K50 and N125P90K100 reduce nematode density by up to 58.62% in roots and 95.88% in soil compared to the treatment without manure and mineral fertilizer. The yield of fresh rhizomes vary from 2.9 to 7.7 t/ha with little statistically effects of the manures. This study reveals that nematodes constitute a serious phytosanitary problem for ginger and that the contribution of organo-mineral fertilization makes it possible to reduce the density of nematodes under ginger.

The article, based on the analysis of scientific works, presents the research findings of the influence of mineral, organic and organo-mineral fertilizer on the biochemical composition of soft wheat grain. It is shown that seed productivity and quality of wheat grain depend on the provision of plants with nutrients during the growth season, resistance to stress factors and biological characteristics of the variety. The yield of winter wheat increases due to super-strong and extra-strong varieties, but the quality of grain, which is negatively correlated with productivity, decreases. Fertilizers are a significant factor in improving the quality of wheat grain, and their use allows to obtain high quality baking flour. Application of different types of organic fertilizers (cattle manure, chicken manure) and green manures (wheat-wheat, oat-pea, mustard) results in an increase in the gluten content from 24.2 to 25.6–27.7 % in grain winter wheat. The application of manure also contributed to the accumulation of proteins in the grain. The quality of wheat grain (nutritional value and baking properties) depends on both the protein content and their amino acid composition. Nitrogen fertilizers have been shown to increase the protein content and the amount of essential amino acids in grain and improve their amino acid composition, but their application, especially in higher doses, reduces the baking properties of wheat flour. The use of nitrogen fertilizers also increases the content of trace elements in wheat grain and improves the nutritional value of this important food. Foliar feeding of plants with chelated micro-fertilizers on the background of complete mineral nutrition (N60P60K60) also improves the quality of grain, while increasing the content of proteins and gluten. Pre-sowing seed treatment and foliar fertilization of plants in the phase of tillering and earing with liquid organo-mineral fertilizer Polidon Bio Zernovyi special purpose for winter wheat, against the background of mineral nutrition (N60P60K60), increased the protein content in grain according to experimental variants and promoted raw gluten growth.

Improvements in crop management for a more sustainable agriculture are fundamental to reduce environmental impacts of cropland and to mitigate effects on global climate change. In this study three fertilization types – ammonium nitrate (control); mineral fertilizer added with a nitrification inhibitor (3,4-dimethylpyrazole phosphate (DMPP)), and an organo-mineral fertilizer (OM) – were tested on a tomato crop in order to evaluate effects both on crop production and soil N<sub>2</sub>O emissions. Plants grown under OM fertilization had a greater relative growth rate compared to mineral fertilization, due to a higher net assimilation rate, which was related to a greater light interception rather than to a higher photosynthetic efficiency. OM fertilization determined the highest fruit production and lower soil N<sub>2</sub>O fluxes compared to NH<sub>4</sub>NO<sub>3</sub>, although the lowest soil N<sub>2</sub>O fluxes were found in response to mineral fertilizer added with a nitrification inhibitor. It can be concluded that organo-mineral fertilizer is a better nutrient source compared to mineral fertilizers able to improve crop yield and to mitigate soil N<sub>2</sub>O emission.

Effects of application of poultry manure, organo-mineral fertilizer, NPK soil or foliar applied at varying rates on cacao seedlings were studied in the nursery between January-May 2011 and December to April, 2012. Poultry manure at 40, 50 and 60g/plant significantly influenced cacao seedlings height and number of leaves over other treatments. The effect of organo-mineral fertilizer application at 50 and 60g per plant on the number of leaves was also significantly better than NPK soil or foliar applied, starting from 12 weeks after treatment application. The stem girth development under poultry manure at 50 and 60g per plant application had the best performance followed by poultry manure at 40g per plant. There were no significant differences in almost all the treatments at 5 weeks after sowing on seedlings stem girth. NPK has the longest tap root length while poultry manure had the largest average number of lateral roots followed by organo-mineral. The results thereby indicated that the use of poultry manure at 40 to 50g per plant and organo-mineral fertilizer as sources of nutrients had significant effects on cacao seedling quality.

Abstract Long-term agricultural use of chernozems (black soils) leads to a decline in their effective fertility. The depletion of the arable and subsoil horizons in calcium can occur under the influence of natural and anthropogenic factors. The strongest anthropogenic impact on physico-chemical properties is caused by varying levels of fertilizer application. Average annual rate of pHkcl decrease on unfertilized variant was 0.008-0.01 units per year. At the same time in the grain-fallow crop rotation the decrease of pHkcl is more intensive than in the grain-grass crop rotation. Under the influence of mineral fertilizers the growth rate of acidity increased by 1.8-2.1 times. After 12 years after application of organic fertilizers the value of acidity increased by 0.13-0.15 units after carrying out the experiment with pHkcl in comparison with initial values. The application of dolomite flour contributed to the increase of pHkcl by 0.41-0.53 units as early as one year after application of the ameliorant, the maximum shift was observed on the 4th-5th years. The application of organic and mineral fertilizers contributed to the trend of increasing the content of available phosphorus in the soil, compared with the unfertilized variant in both crop rotations. The content of mobile forms of phosphorus increased in the variants where green manure crops were sown. The application of manure and mineral fertilizers had no significant effect on the content of potassium in the soil. When using organo-mineral fertilizer system, as well as its combination with crop-sideration, there was a tendency of some increase in potassium content in the arable layer. The minimum additional yield was obtained for all crops with the application of 8 tonnes of manure per hectare of crop rotation land, and the maximum was obtained with the organo-mineral fertilisation system and its combination with crop-sideration. Liming increased the productivity of all crops.

The study aimed to assess the yield, nutrients accumulation and fruit quality of watermelon grown under different NPK rates provided by mineral and organic fertilizers. The experiment was performed at the Federal University of Campina Grande (UFCG), Campus Pombal-PB, during the period from June to September 2013. Treatments consisted of three nutrient concentrations N, P and K (50, 100 and 150% of NPK recommendation for watermelon) and five ratios of mineral and organic fertilizer (100/0, 75/25, 50/50, 25 / 75 to 0/100). The experimental design was in randomized blocks, in a 3x5 factorial scheme with four replicates. The NPK rate corresponding to 100% was 120 kg ha-1 respectively for N, P and K. The following variables were evaluated: fruit yield, nutrient accumulation, titratable acidity, soluble solids and ratio between soluble solids and titratable acidity. The concentration of 150% of nutrients was more effective in increasing the yield for the 75/25, 25/75 and 0/100 ratios of mineral and organic fertilizers, and the concentrations of 100 and 150% were the most effective in the accumulation of soluble solids when applied in the mineral and organic fertilizer ratios of 75/25 and 50/50.

Full textAbstract:
Commercial brands of alternative, organic fertilizers were compared with conventional, mineral fertilizers using head cabbage. There were six different treatments: conventional farmyard manure, Agro (made from poultry bedding and molasses), Dvorecký agroferm (granulated, made from dried, aerobically-fermented farmyard manure), Agormin (an organo-mineral fertilizer), compost manufactured from plant waste material, mineral fertilizer, and an unfertilized control. All the treatments were applied at rates providing approximately the same level of nutrients. After harvest, the levels of the minerals (K, Na, Ca, and Mg), ascorbic acid, nitrates and yield were measured. There were no significant differences between the treatments in levels of K, Na and Ca in case of organic fertilizers (farmyard manure, Agro, Agormin and compost). The unfertilized control had the highest levels of ascorbic acid; it was significantly higher than in case of farmyard manure which, in turn, had significantly higher values than compost. Significant differences between the treatments were found in the levels of nitrates; the lowest in case of Dvorecký agroferm and in the control. The highest marketable yields were recorded with farmyard manure and Dvorecký agroferm, the latter being significantly higher than the control. This study shows that alternative, organic fertilizers (except compost) have similar qualities as farmyard manure.

The issue of scientifically sound fertilizer application in fruit plantations, which are long-term and re-grown in one place remains insufficiently studied. To solve this problem is possible only in long-term stationary studies, as the impact of different fertilizer systems on changes in soil properties and tree productivity for a long period of their use. The results of researches of long-term fertilizer influence on the main fertility indices of dark gray podzolic heavy loam soil and productivity of repeatedly grown apple trees of Idared varieties on seed and vegetative (M4) rootstocks and Calville snow on seedling rootstock are considered. During the 85-year period of growing the first and second generation of apple trees in the experimental garden, the organic fertilizer (40 t/ha of cattle manure), mineral fertilizer (N120P120K120) and their combination (20 t/ha of manure + N60P60K60) were applied in the old plantation every two years in autumn in plowing in rows at 18–20 cm, and in the new repetition: manure, phosphorus and potassium fertilizers as well, and nitrogen fertilizer in half doses annually in spring for cultivation or disk plowing to a depth of 12–15 cm. As a result of research it was found that organic fertilizer better than mineral fertilizers provided the formation of soil fertility (humus and mobile compounds and forms of nutrients, soil reaction) and yield capacity of experimental apple trees, which for all years of fruiting exceeded the total yield of Calville snow and Idared on seedling and vegetative rootstocks, respectively, by 34.8, 27.7 and 23.4 % compared with the yield of the control non-fertilized areas and 16.0, 15.8 and 13.2 % – on those fertilized with N120Р120К120. Similar parameters of soil fertility indicators are formed by the organo-mineral fertilizer system with systematic long-term application of half the norms of organic and mineral fertilizers of manure 20 t/ha together with N60P60K60. However, the mineral system (N120P120K120) significantly less increases the humus content and content of macronutrients available for plant nutrition and does not enrich the soil with trace elements, acidifies the reaction of the soil environment

The aim of the research is to study the intensity of heavy metals accumulation in milk thistle leaf mass under fertilization with the latest types of fertilizers and to assess the environmental safety of such raw materials. Two experiments were laid in the research: the effect of fertilizing milk thistle with organo-mineral fertilizer Growth-concentrate on the intensity heavy metals accumulation by its leaf mass; the effect of fertilizing milk thistle with chelated fertilizers Phosphorus-chelate and Potassium-chelate on the intensity on heavy metals accumulation by the leaf mass. The use of a chelated Phosphorus chelate fertilizer for the fertilization of milk thistle crops leads to a 1.1 times decrease in the contamination of its leaf mass with cadmium and copper in comparison with the option without fertilizing its crops, and the increase in the concentration of lead and zinc compared to the control is insignificant and is within the range errors of experience. The use of fertilization of crops of milk thistle chelated fertilizer Potassium-chelate helps to reduce the contamination of its leaf mass with cadmium compared to the control, and the change in its contamination with copper is within the margin of error. At the same time, replacing the Growth-concentrate fertilizer with Phosphorus-chelate or Potassium-chelate when fertilizing milk thistle crops will lead to a decrease in the contamination of its leaf mass with lead, cadmium and copper, but will increase the contamination with zinc, compared to the control. The most environmentally safe leaf raw material of milk thistle in terms of lead, cadmium and copper content will be observed when fertilizing its crops with chelated fertilizers Phosphorus-chelate, and in terms of zinc content – when fertilizing with organo-mineral fertilizer Growth-concentrate. It is advisable to use Phosphorus-chelate fertilizer for the plant fertilization to reduce the contamination of the leaf mass of the medicinal raw material of milk thistle with heavy metals, in particular cadmium – by 9 % and copper – by 11 %,. To reduce contamination of the leaf mass with zinc by 81 %, it is recommended to use the organic-mineral fertilizer Growth-concentrate. Key words: milk thistle, medicinal raw materials, environmental safety, heavy metals, pollution, fertilizers.

Increased demand for agricultural products leads to soil depletion and increased use of mineral and organo-mineral fertilizers. Mineral fertilizers used in agriculture may contain contaminators such as heavy metals or radionuclides that can migrate and accumulate in plants. Although migration and accumulation abilities directly depend on species in which they are presented. Determination of species of heavy metals and radionuclides can be done by sequential extraction technique, which takes long time and a lot of reactants. Preliminary evaluation can be done on the basis of data of simultaneous thermal analysis. In the present study the simultaneous thermal analysis was used for investigation of mineral fertilizers, purchased in Almaty. “Fasko” with ammonia nitrate and “Bujskie udobreniya” fertilizers contain water-soluble fractions and “Ljubo zeleno” and “Fertika” contain organic soluble fractions.

Using fertilizers, in line with other agrotechnical activities, is one of the most important means for increasing soil fertility, as well as agricultural products performance. Domestic and foreign experience shows us that yield capacity can grow almost 1.5-fold due to fertilizers. Nowadays the surface type of using hard organic and mineral fertilizers by means of body spreaders is considered to be one of the simplest technically and most effective ways. Being the object of the research, the experimental mineral and organo-mineral granular fertilizers spreader is a van-type lowboy, equipped with a belt conveyor and a vertical rotor with a horizontal axis of rotation. In addition to load bearing characteristics, rotational movement of the operative parts in the casing of the rotary drum provides for air drag, which influences the trajectory of fertilizers flight. Pattern of fertilizer distribution, flight distance of fertilizer particles and horsepower input of the gear system depend on the design features of the operative parts of the pneumatic-mechanical rotor. The objective of the research is to define travel speed of fertilizer particles along vanes in case of constant fertilizer input with air drag in versions with radial position of vanes, bent backwards and forwards to some angle. The main research techniques are a graphical and analytical method and analysis of the component force which operates on the blade's surface. As for the drum with a diameter of 920 mm, at rotation frequency of 850 min-1, the best performance was shown by the through blade. They may reduce the friction force of the casing of rotor. Besides, they can concentrate fertilizers in the center of a blade, and achieve qualitative work of the fertilizer spreader, is ascertaining.

The results of the study of the productivity potential of natural phytocenoses of different species composition in the Namsky agrolandscape of the middle taiga subzone of the Republic of Sakha (Yakutia) are presented. The research was conducted in 2009-2016. The soils of the experimental plot are permafrost soils with a thin humus layer. The effect of mineral and organic fertilizers on the productivity of steppe meadows was studied. On herb-grass, wheatgrass, steppificated phytocenoses the following practices of organo-mineral nutrition of plants were used: control (no fertilizer); humus 20 t/ha; humus 20 t/ha once every 4 years + N60P60K60 annually; N30P30K30 annually; humus 20 t/ha annually. The optimum rates of organic and mineral nutrients to improve the productivity potential of natural steppe meadows have been established. The highest productivity potential in the Namsky agrolandscape was obtained with the combined application of organic and mineral fertilizers (humus 20 t/ha once every 4 years + N60P60K60 annually). On herb-grass and wheatgrass phytocenoses hay yield reached 23.0-24.1 c/ha. Yield per 1 ha of metabolizable energy was 27.0-22.4 GJ, fodder units 1472-1663, crude protein 336-371 kg. The content of digestible protein in 1 fodder unit in herb-grass was 92 g, in wheatgrass - 102 g. The annual application of mineral fertilizers at a dose of 60 kg/ha of the active substance provided a 2-fold increase in the productivity of natural phytocenoses, depending on agroclimatic conditions of the growing season. The influence of mineral fertilizers and their joint application with organic fertilizers on the yield of natural phytocenoses is statistically reliable, which indicates the possibility of regulating the productivity of steppificated phytocenoses.

The use of inorganic fertilizers has been reported to have improved pasture productivity, however it has also attributed to soil toxicity, environmental pollution, mineral imbalance, and health hazards among many adverse effects. This made the adoption of organic fertilizers became best alternative to correct nutrients deficiencies in the soil due to their environmental friendly nature and less cost effectiveness. To investigate the comparative advantages of these two types of fertilizer, an experiment was conducted to evaluate the influence of fertilizer types on the nutritive quality of Panicum maximum var. Ntchisi and Andropogon tectorum harvested at 6 and 8 weeks during the wet season. The study was a factorial experiment (4 x 2 x 2), arranged in a split-split-plot design with three replicates. There were 16 treatments to include; fertilizer types (NPK, Aleshinloye organo-mineral fertilizer, poultry manure and control (no fertilizer)), grass species (Panicum maximum var. Ntchisi and Andropogon tectorum) and age at harvest (6 and 8 weeks). Fertilizer treatments were allotted to the main plots while grass species were allotted to sub-plots and again harvest age was allotted to sub-subplots. Sub-samples taken from harvested forage materials were oven dried, properly milled and analysed in the laboratory to determine proximate composition [crude protein (CP%), ash, ether extract (EE%)], fibre fractions [acid detergent fibre (ADF%), neutral detergent fibre (NDF%), acid detergent lignin (ADL%), Cellulose, and Hemicelluloses) and in vitro gas production. Fertilizer types significantly (P<0.0.5) affected ADF, hemicellulose, cellulose and methane (CH4). The grasses fertilized with NPK had the highest value (9.00mL) for CH4. Poultry manure (PM) fertilized grasses recorded the highest value for in vitro dry matter digestibility (IVDMD) (89.38%). Andropogon tectorum fertilized with PM harvested at 6 weeks recorded the highest value for IVDMD (93.00%) and the same grass fertilized with NPK, harvested at 6 weeks recorded the highest values (0.37 mL and 4.70%) for short chain fatty acid and metabolizable energy, respectively. Therefore, this study established that fertilizer applications had an influence on fibre fraction, methane and post-incubation parameters of the grasses investigated.

The lack of a standard method to regulate heavy metal determination in Brazilian fertilizers and the subsequent use of several digestion methods have produced variations in the results, hampering interpretation. Thus, the aim of this study was to compare the effectiveness of three digestion methods for determination of metals such as Cd, Ni, Pb, and Cr in fertilizers. Samples of 45 fertilizers marketed in northeastern Brazil were used. A fertilizer sample with heavy metal contents certified by the US National Institute of Standards and Technology (NIST) was used as control. The following fertilizers were tested: rock phosphate; organo-mineral fertilizer with rock phosphate; single superphosphate; triple superphosphate; mixed N-P-K fertilizer; and fertilizer with micronutrients. The substances were digested according to the method recommended by the Ministry for Agriculture, Livestock and Supply of Brazil (MAPA) and by the two methods 3051A and 3052 of the United States Environmental Protection Agency (USEPA). By the USEPA method 3052, higher portions of the less soluble metals such as Ni and Pb were recovered, indicating that the conventional digestion methods for fertilizers underestimate the total amount of these elements. The results of the USEPA method 3051A were very similar to those of the method currently used in Brazil (Brasil, 2006). The latter is preferable, in view of the lower cost requirement for acids, a shorter digestion period and greater reproducibility.

The results of the influence of pre-sowing seed treatment, the main application of mineral fertilizers and foliar fertilizing with ammonium nitrate, urea, organo-mineral fertilizer D2 or bacterial preparation Escort-bio on the formation of productivity and quality of spring wheat of the Elegia mironovskaya variety are presented. Experimental investigations were carried out on the Chernozem of the South during 2014-2016. In the conditions of the educational, scientific and practical center of the Nikolaev NAU. The results of research showed that the introduction of nitrogen-phosphorus fertilizers before sowing and foliar fertilizing of spring wheat crops on average over three years provided an increase in grain yield by 1.00–1.58 t/ha in variants with water treatment of seeds and by 1.08–1.72 t/ha when processing seeds with microbial preparation Escort-bio. Pre-sowing treatment of escort-bio seeds contributed to the additional production of 0.14–0.28 t /ha of grain, depending on the fertilizer option. The highest grain yield was formed by applying N30P30 for pre-sowing cultivation, treating seeds with a microbial preparation and carrying out the phase of plant exit into the tube of feeding with ammonium nitrate with a dose of N30. Pre-sowing treatment of escort-bio seeds and foliar fertilizing contributed to an increase in the payback of fertilizers by increasing the yield of spring wheat. The maximum specified indicator is determined by the background of bacterial seed treatment, the main application to the sowing of N30P30 and carrying out two top-UPS with organo-mineral fertilizer D2 or Escort-bio. Application of fertilizers and foliar top-UPS on average over three years increased the protein content of spring wheat by 0.7–1.4 %, and gluten – by 1.2–1.9 %. The maximum both indicators of grain quality are determined in the version of the main application of N30P30 with making-up at the beginning of the earing phase with urea at a dose of N30 –14.9 and 28.1 %. The conditional yield of protein and gluten from a hectare of spring wheat sowing with an improvement in the background of plant nutrition grew and reached maximum values in the variants of N60P30 before sowing or N30P30 before sowing with fertilizing with ammonium nitrate at a dose of N30 in the phase of exit to the tube.

Full textAbstract:
Faced with the problem of providing a balanced mineral nutrition to tomato plants in order to strengthen them to better resist viruses, this work proposed to study the effectiveness of fertilizers in the sustainable management of these in South Togo. Five fertilizers were tested on five tomato cultivars namely Caraïbo, Mongal F1, Petomech, Tropimech and Adakamenou during two great rainy seasons (GRS) of 2019 and 2020 following the split-plot design with fertilizers in main plots and cultivars in secondary plots. Weekly observation of virus incidence and severity according to a rating scale (1-5) indicated a very highly significant effect (P < 0.001) under the cultivars for both experiments. Caraïbo, Mongal F1 and Adakamenou were the least susceptible cultivars to virus diseases. Fertilizers only significantly impacted cultivar susceptibility to virus diseases in GRS 2019 where virus disease incidence was low and statistically identical (22.80%; 22.67%) under organic T2 manure (10 t ha-1 of manure) and low dose organo-mineral T3 manure (38 kg N, 15 kg P2O5, 15 kg K2O ha-1 and 5 t ha-1 of manure). The effect of fertilizer-cultivar interactions on virus severity was significant (P < 0.05) in 2020 and very highly significant (P < 0.001) in 2019. The organomineral manure used at a low dose seems to be the best strategy for reinforcing the obtaining of satisfactory fruit yields.

Full textAbstract:
The article presents the results of studies of the systematic use of organic and mineral fertilizers on the parameters of fertility of gray forest soil and the formation of productivity of winter wheat. It was found that in a five-saw field crop rotation, the formation of ground backgrounds with different physical and chemical properties is observed. The application of bedding manure at a dose of 60 t on ha and against the background of moderate fertilization rates (N50-100P30-60K50-100) contributed to the neutralization of the soil solution to values of slightly acidic reaction (pH – 5,1), while in the absence of manure (mineral system fertilizers) pHcontinued to remain within the acidic reaction. The organic-mineral fertilization system (12 t on ha of manure + N100P60K100) and organic (12 t on ha of manure per 1 ha) turned out to be effective in terms of the humus of the soil regime, in accordance with the total humus content was 1,30 % and 1,32 % which in percentage terms is 18 % and 20 % higher compared to the option without fertilization – 1,10 %. Optimization of the parameters of the nutrient regime (mobile forms of phosphorus and potassium) of the soil at the end of the rotation was provided by the organo-mineral fertilization system (N100P60 K100 against the background of 60 t on ha of manure). A clear tendency to an increase (by 27 mg on kg) of the content of mobile potassium was determined, compensating for its constant deficiency in the soil, and by an increase of 38 % in mobile phosphorus. The highest productivity of winter wheat (5,45 t on ha) was provided by the organo-mineral fertilization system (60 t on ha of manure + N100P60K100), which is 78 % higher than the control (without fertilizers), under these conditions the greatest increase in protein was obtained – 0,63 t on ha.

Full textAbstract:
AbstractChemical fertilizers for boosting crop production are becoming more expensive and scarce. Green amaranth (Amaranthus caudatus L.) is a fast growing and highly nutritious crop, but its common use in the diet of Nigerians is constrained by its high demand for nitrogen fertilizer. Thus, there is a need to find local fertilizer materials that are readily available to peasant farmers. A preliminary field study was conducted to evaluate urine and neem (Azadirachta indica L. juss) as alternative sources for mineral fertilizers in fortifying organic fertilizer (OF) made from cow dung and market waste compost, and OF fortified with urea and bone meal [organo-mineral fertilizer (OMF)], for yield and growth of green amaranth. Fifteen treatments, based on the percentages of N supplied, were NPK15-15-15, OMF, OF, urine, neem and ten treatments of 50, 60, 70, 80 or 90% OF supplemented with a total of 50, 40, 30, 20 and 10% urine or neem, respectively, to provide a total application rate of 100 kg N ha−1, with no fertilizer treatment as a control. Planting was done in two successions (main with fertilizer treatments and residual without further application). The fertilizer sources and levels had significant effects on plant height, number of leaves, stem girth, fresh weight and dry weight. The residual effects were also significant for plant height, number of leaves, total fresh and dry weights. Forty percent N urine amendment of the OF produced the highest total fresh amaranth biomass (269.3 g plot−1 main effect and 110.8 g plot−1 residual effect), which was significantly better than the values of (140 and 35.3 g plot−1, respectively) obtained with respect to OMF during main planting and NPK during residual planting. Results of our study reveal that 40% N urine fortification of OF was a viable substitute for synthetic fertilizers in production of amaranth, and that urine and neem cake can be alternatives to mineral fertilizer for crop production.
