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.
