Eaton, Touria E., Douglas A. Cox, and Allen V. Barker. "Sustainable Production of Marigold and Calibrachoa with Organic Fertilizers." HortScience 48, no. 5 (May 2013): 637–44. http://dx.doi.org/10.21273/hortsci.48.5.637.
Full textAbstract:
Experiments were conducted to evaluate organic fertilizers in production of greenhouse-grown calibrachoa (Calibrachoa ×hybrida Llave & Lex) and marigold (Tagetes erecta L.) and nitrogen (N) leaching from containers during production. Calibrachoa was grown with five fertilizer treatments: one chemical, one organic-based, and three organic (liquid fish, oilseed extract, and a combination of oilseed extract and liquid fish). Marigold was grown with seven fertilizer treatments: one chemical and three organic (liquid fish, oilseed extract, and alfalfa pellets) used either alone or in combination. Chemical or organic-based fertilizers produced the best quality calibrachoa based on plant appearance and size. Liquid fish fertilizer produced healthy plants but smaller plants than those grown with chemical or organic-based fertilizers. Plants grown with oilseed extract were stunted and showed chlorosis. If oilseed extract was combined with liquid fish, the plants were similar to those grown with the chemical or organic-based fertilizers in size and quality. Chemical or liquid fish fertilizers produced the highest quality marigold based on plant appearance. Plants fertilized with alfalfa pellets were sparse and pale green. Oilseed extract produced the poorest growth and quality. If oilseed extract was combined with liquid fish or alfalfa, marigold plants were close in size and development to chemical-fertilized plants without nutrient deficiency and with some enhancement of nutrient levels in the leaves. The combination of alfalfa and liquid fish produced similar results. The highest N leaching resulted from plants fertilized by liquid fish, mostly in the form of ammonium nitrogen (NH4-N). Combining liquid fish with alfalfa or oilseed extract reduced the amount of N leached from the pots. The results suggest that organic fertilizers can be used successfully to grow commercial greenhouse crops but should be combined for good plant quality and environmental sustainability.

The word as in general has the responsibility to respond to the emerging food crisis to match the growing population. Africa and many other Low Income Countries under Stress [LICUS] will face a stiffer challenge. Africa and specifically Sub-Saharan Africa depends much on synthetic fertilizers with disease burden. The concept and awareness of Organic Fertilizer and its Utilization in Agro farming with attendant benefits in Nigeria is at its lowest ebb. This review highlighting availability, of Liquid Organic Fertilizer in Nigeria agro-allied market among farmers and the awareness/benefits in Organic farming reveals much on the scale of 10. 1-3 reliable fertilizers companies are visible with most emphasis on synthetic fertilizer blending only. 1-2 reliable fertilizer company manufactures urea and synthetic fertilizer from which other companies get involved in the distribution. 1-2 claimed that their fertilizers are purely organic in powdered sachet forms. 1-3 claimed to produce liquid organic fertilizer alongside synthetic fertilizer formulation. 1-2 notable liquid organic fertilizers available claimed foliar mode of application. 2 out of 10 makes use of solid human wastes for liquid organic fertilizer. 5 out of 10 liquid organic fertilizer were found to be compost in nature while 2 out of 10 claimed to be organic liquid in nature. 1 3 Liquid Organic Fertilizers encountered cannot be verified by literature on their composition, materials and process of production. The available liquid organic fertilizer in Nigeria is with mixed acceptance. Synthetic fertilizer manufacturers claimed that their products can be used as organic fertilizer. Droppings from animal waste claimed their products are manures and fertilizers. Other liquid organic fertilizer companies claimed use of sea weeds without clear mechanism of actions. Nevertheless, a liquid fertilizer company located in Kuje, Abuja has been identified to possess state of art product line facilities with purely organic materials as source.

The objective of the study was to utilize the biogas effluents to produce solid and liquid organic fertilizers, as well as evaluate their effect on the growth and yield of corn and mung beans under field conditions. For liquid organic fertilizer, biogas effluents were mixed with fish emulsion and beneficial bacteria while biogas effluents-absorbing coal slag was mixed with sugarcane filter, fishmeal and beneficial bacteria to create solid organic fertilizer. Liquid organic fertilizer was irrigated with a dose of 5 L/1000 m2 while solid organic fertilizer was applied with a dose of 1 ton/ha with 75% recommended NPK formula for maize and mung bean. The results showed that applying solid or liquid organic fertilizer formulated from biogas effluents with other amendments helped to reduce the amount of recommended NPK fertilizer by 25%, but still maintained growth and yield of maize and mungbean equivalent to the control treatment fertilized with 100% recommended NPK. In conclusion, the amount of organic matter and N, P, K in biogas effluents from biogas digesters can be utilized to produce organic fertilizers which not only help to reduce chemical fertilizers, but also solve the environmental problems and create new friendly value-added products for practicing sustainable agricultural production.

Full textAbstract:
Liquid compound fertilizers (LCF) are aqueous salt solutions which nourish the soil. They contain nitrogen, phosphorus, potassium, sometimes calcium, magnesium and micronutrients. An LCF solution has practically no insoluble residue and contains the elements in a fully digestible form and is a high-speed, highly effective fertilizer. It is important to assess the equilibrium in the solid-liquid system when creating liquid compound fertilizers, since their basic properties, concentration and crystallization temperature, depend on it. The aim of the study was to determine properties of a liquid multicomponent (K+, NH4 +, Cl- and PO4 3-) system. This liquid multicomponent system, which was obtained as a by-product in the conversion of KCl and NH4H2PO4, can be used as a liquid fertilizer. This work investigates liquid fertilizers? chemical composition and their physicochemical properties, such as crystallization temperature, pH, density, viscosity and corrosivity. In order to increase nitrogen concentration, ammonium nitrate was added. Composition of the solid phase obtained by crystallization was identified by methods of chemical and instrumental analysis (radiography, infrared molecular absorption spectroscopy and optical microscopy). The results show that all properties of liquid fertilizers are best when the concentration of NH4NO3 in liquid solutions equals 8%.

Abstract The field trial was carried out in 2016 and 2017 on the grounds of the Botanical Garden of the Slovak University of Agriculture in Nitra. The aim of the paper was to test the impact of new organic fertilizers from Company Rokosan on the yield parameters and the morphological and phenological properties of tomatoes. In the experiments, we observed two determinant varieties, namely ‘Brixol F1’ and ‘Uno Rosso F1’. We used the bulk organic fertilizer Rokosan P, designed for fruiting vegetables, and the liquid fertilizer Rokohumin Z. Both forms of fertilizers are produced as organic biomineral fertilizers, their main ingredient being keratin. They contain 9% N, 9% P2O5, 9% K2O, 3% MgO and trace elements. The total harvest in the control variant without fertilization was the lowest compared to the fertilized variants. The second variant was fertilized with the Rokosan P fertilizer, and the harvests were in both years and in both varieties higher than in the variant 1. The third variant was fertilized with the Rokohumin Z, the liquid fertilizer and achieved the best crop yields per plant. For the ‘Uno Rosso F1’ the best total harvest weight was 7.2 kg per plant in 2016 and 8.96 in 2017. For the ‘Brixol F1’, the highest harvest was 8.14 kg per plant in 2016 and 9.24 kg in 2017. In terms of yields and the number of fruits, combined fertilization with the bulk fertilizer Rokosan P and the liquid fertilizer Rokohumin Z reached the second highest values.

Millets are small-seeded grasses belonging to the family Poaceae that help in human and animal nourishment. They are mostly grown by using chemical fertilizers which are depleting soil fertility. Organic fertilizers are eco-friendly and help to enhance the growth and development of plants thereby maintaining soil health. Seaweed liquid fertilizer (SLF) are organic fertilizers that can be used to control the side effects caused by harmful chemical fertilizers. The present study was carried out to check the effects of seaweed liquid fertilizer on the growth and development of millets. Different concentrations of seaweed liquid fertilizer (0.25%, 0.50%, and 0.75%) were prepared from Sargassum cinerum, Ulva intestinalis, and Padina tetrastromatica, which were tested on Sorghum bicolor and Pennisetum glaucum. Growth parameters like root length, shoot height, flowering-fruiting, and biochemical analysis like proteins were analyzed by using seaweed liquid fertilizer and chemical fertilizer. Plants treated with 0.50% concentration of seaweed liquid fertilizer showed higher protein content. Total chlorophyll was found to be higher in treated plants than in control plants. Flowering and fruiting were observed earlier in seaweed liquid fertilizer treated plants. This concludes that seaweed extracts can be used as a promising alternative to chemical fertilizers, which plays a significant role in the holistic growth enhancement of plants.

The Kalimbu market is one of the traditional markets in South Sulawesi with a very high buying and selling activity. The organic waste that is mostly generated from the activities at the Kalimbu Market is leftover vegetables and fruit. Vegetable and fruit waste provides a big advantage if it is managed properly, which is converted into liquid organic fertilizer through a fermentation process. The liquid organic fertilizers produced can help farmers overcome the high price of synthetic fertilizers and save the earth from pollution. The method used to determine the effect of types of organic waste (vegetable waste and fruit waste) on the physical and chemical quality of solid and liquid organic fertilizers used a randomized block design. Whereas the application of solid and liquid organic fertilizers to the production and nutritional content of potato plants used a treatment consisting of P0: basic fertilizer + without liquid organic fertilizer and P1: basic fertilizer + liquid organic fertilizer. The results of research on the manufacture of liquid organic fertilizer from Kalimbu market waste with vegetable and fruit samples also showed that the two samples required different storage times for composting. Plants treated with liquid organic fertilizer from the Kalimbu market waste have better stem growth, leaf number, and stem number.Keywords: Waste, organic, fermentation, hydroponic

In modern agriculture, the extensive use of chemical fertilizers has resulted in the degradation of soil fertility, leading to acidity and instability, making it unsuitable for agriculture. This overreliance on inputs has contributed to severe health hazards and environmental pollution. The experiment on finger millet focuses on analyzing the effectiveness of growth-promoting natural fertilizers. The findings highlighted that a liquid organic fertilizer made from vegetable peels exhibited a superior composition of nutrients compared to the vermicompost manure and garden soil. This liquid fertilizer contained high levels of essential nutrients such as N, P, k, B, S, Zn, Fe, and Mn, crucial for promoting plant growth. Its efficacy lies in fostering better nutrient absorption through the establishment of a symbiotic relationship between microbes and plants. Results indicated that finger millets cultivated with the liquid fertilizer displayed superior and robust growth compared to those grown in garden soil with vermicompost. This presentation underscores the potential of liquid organic fertilizers (LOF) as a noteworthy alternative to chemical fertilizers, contributing to improved sustainable crop growth and yield. LOFs emerge as a beneficial tool for farmers, to explore the effective use of echo-friendly, cost-effective.

AbstractThe demand for organic foods is increasing globally, but a key limiting factor to the production of organic greenhouse produce is the lack of certified liquid fertilizers. In this experiment, four organic fertilizers were produced using either acidic extraction, anaerobic digestion or both of ensiled biomass of organic red clover and white mustard. The resulting fertilizers were applied to greenhouse-grown parsley either alone, or in combination with nitrogen (N)-enriched water produced by flushing acidic water with ammonia, to determine their effect on plant growth and the nutrient concentrations of parsley. Six combinations of fertilizer treatments were included in the greenhouse experiment. Three treatments received either fertilizers derived from acidic extraction, anaerobic digestion or both and three treatments received fertilizers derived from acidic extraction combined with N-enriched water. Conventional inorganic liquid fertilizer, chicken manure extract and no liquid fertilizer (only water) were added as control treatments. A higher N-min (ammonium and nitrate) to potassium (K) ratio was found in fertilizers after anaerobic digestion compared to acidic extraction. All organic fertigation treatments resulted in high pH, high K and chloride concentrations and high NH4/NO3 ratios in the root zone. In addition, high electrical conductivity (EC), P, K and Mg concentrations were found when only acidic extracted fertilizers were applied. Application of plant-based organic fertilizers without amending with N-enriched water resulted in biomass yields that were 21–26% lower than the inorganic fertigation control. However, fertigation with chicken manure extract, or a combination of fertilizer derived from acidic extraction and N-enriched water, resulted in similar plant growth as inorganic fertilizer. The lower yield from fertilizer derived from acidic extraction was due to elevated EC levels in the growing medium. Our results suggest that yield of greenhouse-grown parsley using either organic fertilizers combined with N-enriched water or chicken manure extract is similar to conventional fertilizer.

The study discusses the results of the analysis of changes in the management of natural fertilizers in Poland and voivodships. Analysis included changes in: the number and percentage of individual farms using natural fertilizer, fertilized area, and level of consumption of particular fertilizer types. The comparative analysis at a voivodship level concerned the years 2007 and 2016. The current situation with regard to fertilized area and natural fertilizer rates was also assessed on the basis of Statistics Poland data from the years 2018-2019. The results of analyses indicated that the number of farms using natural fertilizers in Poland has clearly decreased. Despite observing an increase in the interest in slurry application, the most popular natural fertilizer applied is still manure, which, in the years 2018-2019, was applied on 18% of utilized agricultural area. In Poland, the average annual rates of applied manure, liquid manure and slurry are, respectively 17 t/ha, 22 m3/ha and 26 m3/ha. An analysis of the organization and intensity of natural fertiliser management in the Podlaskie Voivodeship shows that this is the leading region in this aspect, which confirms its dominant position in livestock production in Poland.

Fertilizer is the main needed for farmers to support agricultural products. However, the availability of chemical fertilizers in the market was once scarce due to its limited availability. To avoid dependence on the need for chemical fertilizers is to look for other alternatives as plant fertilizers. One alternative to chemical fertilizers is compost produced from organic waste. Compost fertilizer is available in several forms, namely solid fertilizer and liquid fertilizer. In this community service, training was conducted on making a simple composter to make organic fertilizer. The composter produced in this activity is very easy to do and made by partners because it comes from materials that are easily obtained around partners. The advantage of this composter is that it can produce both solid fertilizer and liquid fertilizer at the same time, but the concern of the service team is a liquid fertilizer because its use is more practical and easier for plants to absorb. During the training process, the partners were very enthusiastic about participating in the activity and asking questions related to composting. In this composter, the waste used is organic waste resulting from household waste which is placed at the top of the composter. Then the composter is closed and allowed to ferment by microorganisms. The results of organic liquid fertilizer can be accommodated at the bottom of the composter and then applied to plants in a ratio of 1:10.

Bearing `Misty' and `Star' southern highbush blueberries were grown on pine bark beds and fertilized at three rates using granular and liquid fertilizers with a 3–1–2 (1N–0.83K–0.88P) ratio. Granular fertilizer was applied 8 times per year at 4-week intervals beginning in April and continuing through October. Liquid fertilizer was applied with low volume irrigation 16 times per year at 2-week intervals during the same period. During the growing season, irrigation was applied at 2- to 3-day intervals in the absence of rain. A 2 cultivar × 2 fertilizer type × 3 fertilizer rate factorial arrangement of treatments was replicated 8 times in a randomized complete-block design. All fruits were harvested from single-plant plots at 3- to 4-day intervals. Canopy volume was not affected by fertilizer type, but fruit yield was slightly greater for granular than for liquid fertilizer treatments. In 2003, fruit yield of 2.5-year-old `Misty' and `Star' plants increased with increasing fertilizer rates up to the highest rate tested (50 g N/plant/year). Similarly, in 2004, fruit yields increased with increasing fertilizer rates up to the highest rate (81 g N/plant/year). Root distribution was limited to the 12-cm-deep layer of pine bark with very few roots penetrating into the underlying soil. The positive growth responses of blueberry plants to high fertilizer rates in pine bark beds suggests that soluble fertilizer was leached through the pine bark layer into the soil below the root zone. More frequent, lighter applications of soluble fertilizers, use of slow-release or controlled-release fertilizers, and careful irrigation management may improve fertilizer use efficiency of blueberry plantings on pine bark beds.

ABSTRACT The growth of good and quality seeds requires a lot of fertilization, considering that oil palm seeds grow quickly. Generally, the fertilizers used are compound fertilizers and inorganic single fertilizers. Continuous use of inorganic fertilizers without being balanced by organic fertilizers can reduce soil quality. Therefore, alternative fertilizers are needed to reduce the use of inorganic fertilizers. Liquid smoke from palm oil midrib-leaf waste can be developed into organic fertilizer, so a lot of studies are needed. This study aims to determine the growth of oil palm seedlings by giving liquid smoke from palm oil midrib-leaf waste. The treatments given were P0 (0% /control), P1 (2% liquid smoke), P2 (3% liquid smoke), P3 (4% liquid smoke), P4 (5% liquid smoke), P5 (10% liquid smoke ), P6 (15% liquid smoke) and P7 (20% liquid smoke). The results obtained are analyzed. A further BNJ test will be carried out at the 5% level if they give significantly different results. Parameters observed were plant height (cm), number of leaves (strands), leaf area (cm2), and diameter of stem circumference (mm). The application of liquid smoke from the palm fronds had a significant effect on plant height and leaf area of oil palm seedlings, while the parameters of the quantity leaves and stem diameter had no significant effect. The best treatment based on plant height and leaf area parameters was 2% liquid smoke from palm oil midrib-leaf. Keywords: liquid smoke, palm oil midrib-leaf, palm oil

Abstract Organic fertilizers are necessary for environmentally friendly agriculture. The study aimed to determine rice response to manure and liquid organic fertilizer application ratio. The study was conducted by experimental method with a Complete Randomized Design with five replications. The treatment consists of 6 treatments, namely organic fertilizer, 25% goat manure + 75% commercial liquid organic fertilizer, 50% goat manure + 50% commercial liquid organic fertilizer, 75% goat manure organic + 25% commercial liquid organic fertilizer, 100% goat manure, and 100% manure goats + 100% commercial liquid organic fertilizer. The results showed that plant height during the middle of the vegetative phase treatment of 25% goat manure + 75% commercial liquid organic fertilizer was higher than the treatment of 50% solid organic fertilizer goat manure + 50% commercial liquid organic fertilizer and 100% treatment of goat manure solid organic fertilizer. The root length and volume of treatment 25% goat manure + 75% commercial liquid organic fertilizer is longer and higher than the combined treatment of manure and other liquid organic fertilizers. The grain weight per clump of mixed manure and liquid organic fertilizer treatment is no different. In the future, treatment of 25% goat manure + 75% commercial liquid organic fertilizer can be applied to increase the rice roots.

Full textAbstract:
Liquid fertilizers are often used in the middle of the growing season in an attempt to enhance organic carrot (Daucus carota var. sativus) yield and quality, although their effect on plant performance is unproven. The impact of liquid organic fertilizers and foliar seaweed applications on carrot yield and quality characteristics were evaluated on certified organic land at the Colorado State University Horticulture Field Research Center in Fort Collins, CO, USA, in 2014 and 2015. Hydrolyzed and non-hydrolyzed fish fertilizer and cyanobacterial fertilizer (cyano-fertilizer) treatments were applied through a drip irrigation system at prescribed N rates about every 10 days throughout the growing season. Each treatment, including the unfertilized control, was repeated with the addition of concentrated organic seaweed extract, containing phytohormones, applied foliarly at the manufacturer’s recommended rates. The cyano-fertilizer treatment resulted in longer carrots in 2014 and the highest carrot yield in both years, with it consistently yielding equal to or greater than either hydrolyzed or non-hydrolyzed fish fertilizer. The foliar seaweed applications had no effect on carrot yield in either year. The cyano-fertilizer performed comparably to the other fertilizers, suggesting that cyano-fertilizer could be a viable alternative to organic liquid fish fertilizers.

Foliar application of fertilizers on turfgrass via overhead fertigation or spray can improve nutrient absorption efficiency and uniformity. Foliar fertilizers can also be combined with other chemical applications to save labor and energy. However, foliar application of nitrogen may result in root growth reduction. The objective of this study was to evaluate if a liquid organic amendment can be tank-mixed with liquid fertilizer to improve creeping bentgrass (Agrostis stolonifera) performance. This greenhouse study was conducted on ‘Penncross’ creeping bentgrass grown in sand or 90 sand:10 peat (v/v) root zones. Three fertilizer packages (4N–0P–0.8K, 29N–0.9P–2.5K, and 20N–8.8P–16.6K) with or without the organic amendment, a liquid suspension derived from naturally mined humic materials, were tested in the study. Tank-mixing organic amendment resulted in better or same turfgrass visual quality and lower clipping yield compared with foliar fertilization alone. Tank-mixing organic amendment in liquid fertilizers resulted in an average increase of root/shoot biomass ratio from 0.62 to 0.65 grown in the sand-based root zones. The effect of organic amendment was shown in all liquid fertilizers tested except 20N–8.8P–16.6K. The results showed tank-mixing organic amendment with the right liquid fertilizer can reduce mowing frequency without reducing the turf quality. Field work is needed to test if the increased root/shoot biomass ratio by tank-mixing organic amendment with liquid fertilizer can contribute to drought tolerance in creeping bentgrass maintained at fairway height in sand-based root zones.

Full textAbstract:
Liquid-fertilizer deep-application techniques are techniques for applying fertilizers to the root system of crops, which can effectively improve the utilization rate of fertilizers and reduce application amounts. Due to the soil viscosity of soils in the cold region of Northeast China, the soil return rate of furrow openers for liquid-fertilizer deep applications is low, which can easily cause excessive volatilizations of liquid fertilizers. Therefore, aiming at the operational requirements of low soil disturbance for liquid-fertilizer furrowing and deep applications, an efficient soil-returning liquid-fertilizer deep-application furrow opener was innovatively designed based on soil characteristics during the inter-cultivation period in the cold region of Northeast China. The discrete element method (DEM) was used to analyze the operating performance of the high-efficiency soil-returning liquid-fertilizer deep-application furrow openers, which is determined by key operating parameters including width and slip cutting angle. The DEM Virtual Simulation Experiment results show that the optimal combination is the width of 37.52 mm and a slip cutting angle of 43.27°, and the test results show that the optimal performance of the high-efficiency soil-returning liquid-fertilizer deep-application furrow opener is that the soil disturbance rate is 51.81%, and the soil-returning depth is 52.1 mm. This paper clarifies the relationship between the width and the slip cutting angle in furrowing resistance and soil disturbance and the mechanism by which the width and slip cutting angle affect soil disturbance. Above all, this study provides a theoretical and practical reference for the design of liquid-fertilizer deep-application furrow openers.

Abstract The decline in agricultural land productivity due to climate change and excessive use of inorganic fertilizers requires us to implement an environmentally friendly cultivation system, by reducing the application rate of inorganic fertilizers and combining them with organic fertilizers. Liquid organic fertilizer (LOF) is one type of fertilizer that is expected to increase plant growth and yield and reduce the dose of inorganic fertilizers. The objective of this study was to examine the effect of LOF on growth, the yield of sweet corn, nutrient uptake, and the fertilizer use-efficiency of inorganic fertilizers. This Research has conducted at Inceptisol Galuga Bogor, with a randomized block design as an experimental design. The treatments consisted of a control, five doses of LOF and 2 doses of NPK fertilizer. The results showed LOF fertilizer at a dose of 0.75 - 3.0 l ha−1 combined with 100% NPK and 75% NPK increased the yield of fresh cobs by 15% - 19% compared to NPK without LOF. The weight of fresh cobs fertilized with LOF with 100% NPK was (14.63 - 16.68 t ha−1) with RAE= 130 - 205%, which is higher than without LOF (13.73 t ha−1). The combination of LOF with 75% NPK gave the weight of fresh cobs (11.88-15.12 t ha−1) with RAE = 115-507 %, which is higher than without LOF (11.75 t ha−1). LOF can contribute to NPK fertilizer efficiency by 25% of the dose. Nutrient use-efficiency for N is well-managed but lower for P and K.

The topical challenge for the Polish, European, and global fertilizer industry is to produce sufficient nutrients for growing plants using more energy-efficient and environmentally friendly methods. The appropriate course of action, in terms of the challenges posed, could be the production of liquid fertilizers, made from waste materials that exhibit fertilizer properties. This solution makes it possible not only to reduce the exploitation of natural resources but above all, to implement elements of a circular economy and reduce the energy intensity of the fertilizer industry. This study shows that both in Poland and the European Union, there are current regulations aimed at elements of a circular economy and indicating the need to obtain fertilizers containing valuable plant nutrients from organic waste or recycled materials. The recognition carried out for the Polish market clearly indicates that to produce liquid organic fertilizers and soil conditioners, the most used is the digestate from the fermentation process. The preparation of liquid organic–mineral fertilizers is mainly based on algae extracts. Mine minerals are used in the production of mineral–liquid fertilizers. An analysis of data has shown that the above-mentioned waste materials, used as substrates to produce fertilizers, contain chemical substances and elements important for, among other things, stimulation of proper plant development, growth of aboveground and underground parts of plants, increased resistance to diseases and pests, and regulation of plant water management. Referring to the above information, the production of liquid fertilizers from waste materials seems reasonable and is an alternative to mineral–solid fertilizers, whose production process is energy-intensive and produces air emissions. Detailed identification of the properties of the various components made it possible to demonstrate their usefulness in terms of fertilizing plants and soils, but also to emphasize the importance of this line of research and the need to look for other groups of waste for reuse within the framework of a circular economy.

he continuous use of chemical fertilizers indirectly impacts the environment and soil fertility quality, both chemically, physically, and biologically. One way to anticipate this is by using organic fertilizers in cultivation activities. This research aims to: 1) test several types of liquid organic fertilizers that are best in enhancing the growth and production of mustard greens; 2) analyze the best interval of application of liquid organic fertilizers in improving the growth and production of mustard greens, and 3) identify the interaction between the type of liquid organic fertilizer and the interval of application on the growth and production of mustard greens. This research was arranged factorially in a Randomized Complete Block Design. The first factor is the type of liquid organic fertilizer consisting of POC 1 and POC 2, and the second factor is the interval of POC application (0, 1 time, 2 times, and 3 times a week). Data homogeneity was tested using the Bartlette Test, and data additivity with the Tukey Test, then analysis of variance was conducted, and mean value testing was carried out using the Least Significant Difference (LSD) Test at the 5% level. The results showed that the type of liquid organic fertilizer did not affect the growth and production of mustard greens, the best application time for the growth and production of mustard greens was once a week, and the best interaction affecting the growth and production of mustard greens was with the first type of liquid organic fertilizer applied once a week.

Limited soil nitrogen (N) availability is a common problem in organic vegetable production that often necessitates additional N fertilization. The increasing use of drip irrigation has created a demand for liquid organic fertilizers that can be applied with irrigation. The N availability of three liquid organic fertilizers was evaluated in an incubation study and a greenhouse bioassay. Phytamin 801 contained fishery wastes and seabird guano, while Phytamin 421 and Biolyzer were formulated from plant materials. The fertilizers ranged from 26 to 60 g·kg−1 N, 8% to 21% of which was associated with particulate matter large enough to potentially be removed by drip irrigation system filtration. The fertilizers were incubated aerobically in two organically managed soils at constant moisture at 15 and 25 °C, and sampled for mineral N concentration after 1, 2, and 4 weeks. In the greenhouse study, these fertilizers and an inorganic fertilizer (ammonium sulfate) were applied to pots of the two organically managed soils with established fescue (Festuca arundinacea) turf; the N content of clippings was compared with that from unfertilized pots after 2 and 4 weeks of growth. Across soils and incubation temperatures, the N availability from Phytamin 801 ranged from 79% to 93% of the initial N content after 1 week, and 83% to 99% after 4 weeks. The plant-based fertilizers had significantly lower N availability, but after 4 weeks, had 48% to 92% of initial N in mineral form. Soil and incubation temperature had modest but significant effects on fertilizer N availability. Nitrification was rapid, with >90% of mineral N in nitrate form after 1 week of incubation at 25 °C, or 2 weeks at 15 °C. N recovery in fescue clippings 4 weeks after application averaged 60%, 38%, and 36% of initial N content for Phytamin 801, Phytamin 421, and Biolyzer, respectively, equivalent to or better than the N recovery from ammonium sulfate.

Applying organic fertilizer and intercropping systems are among the techniques for preserving land sustainability in organic vegetable production systems. In organic vegetable production, the use of liquid organic fertilizer has been suggested in addition to the use of solid organic fertilizer. This study evaluates how growth and yields of sweet corn and peanuts grown utilizing row intercropping respond to different vermicomposting dosages. A factorial experiment is arranged using a split-plot design with three replicates. The main plot is vermicomposting dosages; 5, 10, 15, 20, and 25 Mg/ha, and the sub-plot was the applications of liquid organic fertilizer, not fertilized and fertilized with liquid organic fertilizer. Results show that the application of liquid organic fertilizer elevated plant height and leaf area, length, diameter, and weight of husked ears of sweet corn. Vermicomposting increased plant height, husked ear length, husked ear diameter, and husked ear fresh weight of sweet corn. Twenty Mg/ha is the best dosage for producing sweet corn intercropped with peanuts. However, using vermicompost and liquid organic fertilizers did not increase the growth and yields of peanuts. Evaluation of nutrient uptakes by intercropped crops, sweet corn, and peanut, in organic production systems, should be the subject of further study.

The urgency of the matter. In recent years, there has been a high demand for various types of complex NPK fertilizers in the world mineral fertilizer market. This situation is primarily related to their high agrochemical value, because such fertilizers allow to introduce all three most important nutrients into the soil at the same time - nitrogen, phosphorus and potassium.Plant growth, development and high yields are directly related to their nutrition. Fertilizers have a great role in providing plants with nutrients. They are important in increasing soil fertility, increasing the productivity of agricultural plants and improving the quality of the obtained product. As we know, fertilizers with nutrient elements should be applied separately to the soil¬¬copper has a number of disadvantages. All mineral fertilizers contain several chemical elements, some of which can harm plants. So, e.g. in the production of phosphorous fertilizers, CaSO4 obtained as a result of processing phosphates with sulfuric acid is introduced into the soil as a ballast. Also, a certain amount of fluorine is transferred to the soil with superphosphate. During the processing of phosphates with nitric acid, the active hydrogen ion is used to split the phosphates, while the anions remain as the desired nitrogen component in the finished product. However, a slightly higher dose of nitrogen fertilizer can lead to a decrease in soil fertility and contamination of food products¬¬causes Thus, in the obtained product, nitrates increase, vitamin "C", sugar decreases, the plant develops unilaterally, which lowers its biological value. Ka¬¬lium fertilizers are also very necessary for plants. However, most potash fertilizers contain ballast elements (CI, Na). When high doses of systematic fertilization are carried out, they accumulate in the soil and reduce fertility, ultimately not improving the quality of either the plant or the soil. Other metals contained in it (Cd, Hg, Pb, Al) can accumulate in living organisms and cause various poisonings by entering groundwater. In this regard, also with macro and micronutrients¬¬¬¬ha highly concentrated and agrochemically more effective liquid complex fertilizer¬¬¬¬¬¬¬¬¬organization of the production of seeds, including NPK¬¬The production of complex fertilizers rich in trace elements is an actual problem of the modern era. The most interesting are concentrated NPK (nitrogen, phosphorus, potassium) liquid-complex fertilizers. Nitrogen-based fertilizers use ammonium nitrate and urea, the nitrogen content of which is 35.0% and 46.7%, respectively. In the first case, the product is called nitroammophos, in the second - carboammophos. Keywords: NPK fertilizers, plants, raw materials

SummaryIn a 3-year plot experiment on a perennial ryegrass plus white clover sward the pH of the soil on the main plots was adjusted to, and maintained as nearly as possible at, target levels of 5·25, 6·00 and 6·75 by applying either sulphur or lime. Within the main plots the effects on herbage yield, clover content and crude-protein content of applying four fertilizers were compared at nitrogen rates of 225 and 450 kg/ha annually. The fertilizers were liquid manure (urine plus water), prilled urea, a urea solution and an ammonium-nitrate fertilizer. The applications of the urea and the ammonium-nitrate fertilizers were accompanied by dressings of a potassium fertilizer which supplied the same weights of potassium as in the liquid manure. On average the smallest yields of dry matter and crude protein were associated with the lowest soil pH with no significant interactions between pH and fertilizer treatment. The liquid manure gave slightly smaller total yields of mixed herbage dry matter than the other fertilizers, particularly at the low nitrogen rate. The herbage from the liquid manure treatment had a higher clover content and produced a greater total yield of clover dry matter. The effects of the liquid manure on the clover agree with those noted in previous experiments, but no evidence was found that these effects resulted from the liquid manure increasing the pH of the soil and improving the conditions for clover growth. Similarly, no proof was obtained that the clover effects were due to the nitrogen in the liquid manure being wholly in the ammonium form. However, the value of liquid manure as a fertilizer for grassland was demonstrated clearly.

Spathiphyllum Schott. 'Mauna Loa Supreme' grown for 6 months in a fine sand soil or a 5 pine bark: 4 sedge peat: 1 sand medium (by volume) were fertilized with 7.6g N, 1.4g P, and 4.5g K/3.5-liter container by 4 different methods. The same raw fertilizer prills (21N-3P-12K) were applied weekly as a liquid, monthly as soluble granules, bimonthly as a lightly resin-coated fertilizer (Osmocote), or every 6 months as a heavily resin-coated fertilizer. All leachates were collected and were measured and analyzed weekly for N O3, PO4, and K. Spathiphyllum grew best in the sand soil with either of the controlled release formula- tions, but fertilization method had no effect on growth in the potting medium. Nitrate and K leaching losses from the potting medium were lowest from the controlled release fertilizers and highest from the soluble granules. Liquid fertilization resulted in the highest amounts of PO4 lost to leaching and controlled release fertilizers the least. In the fine sand soil, NO3 leaching was equivalent from all methods. Soluble granules had the highest levels of leached K and PO4 and the lightly-coated fertilizer lost the least due to leaching.

The potato (Solanum tuberosum L.) is a crucial food source highly demanded in Indonesian society. The national potato crop productivity in 2018 was approximately 1,284,773 tons. Enhancing potato availability necessitates increasing productivity by expanding cultivation areas and employing improved cultivation techniques. However, excessive use of inorganic fertilizers may adversely affect soil fertility and quality. Therefore, it is imperative to enhance soil fertility by augmenting organic matter content using organic fertilizers, such as liquid organic fertilizers derived from processed sugar cane residue. Consequently, this study aimed to ascertain the optimal dosage of liquid organic fertilizer for enhancing the growth and yield of potato plants. The research was conducted from June to October 2022 in Nongkojajar Village, Tutur District, Pasuruan Regency. Various tools were utilized, including hand tractors, nameplates, bamboo pegs, gembor, tape measures, a 150 L drum, a stirrer drill, 5 L and 250 mL measuring cups, waring, and a camera. Potato seeds of the granola variety, liquid organic fertilizer, inorganic fertilizers (Urea, SP-36, and KCL), as well as soil and water samples, constituted the materials for the research. The experimental research method was employed, utilizing an environmental randomized block design (RBD) with seven treatments repeated four times. Parameters observed encompassed plant height, number of leaves, leaf area, dry weight, plant growth rate, soil chemical analysis, nutrient absorption, and harvest analysis. The results revealed that the treatment of liquid organic fertilizer at a 100% dose and the combined treatment of liquid organic fertilizer at doses of 50%, 100%, 150%, and 200% + 80% inorganic fertilizer exhibited superior productivity in potato plants compared to the control treatment without fertilizer. Additionally, these treatments demonstrated comparable potato plant productivity to that achieved with the 100% standard dose of inorganic fertilizer.

Abstract Bacterial compatibility testing is very important to determine which bacteria will be consorted as bio activators when making liquid organic fertilizer. Bacteria that are inoculated into the manufacture of liquid organic fertilizers must have a cooperative and synergistic relationship with fellow bacteria to be efficient in their role as bio activators. To obtain this potential, a compatibility test against bacterial isolates needs to be carried out so that liquid organic fertilizers will be made efficient and effective. The research purposes are to obtain the compatible properties of functional bacterial isolates and their impact on liquid organic fertilizer’s nutritional content. The study was carried out at the Plant Protection Laboratory and Greenhouse of the Payakumbuh State Agricultural Polytechnic, West Sumatra from July to September 2022. The research method began with the rejuvenation of the dry bacterial isolates of Pseudomonas aeruginosa, Bacillus subtilis, Bacillus cereus, and Bacillus thuringiensis. Followed by the compatibility test using the double culturing method, a total of 20 treatments with three replications. The bacterial consortium is inoculated into the manufacture of fertilizer. The results of the compatibility test against P. aeruginosa and genera of Bacillus showed all treatments were compatible which was indicated by the absence of a halo inhibition zone with a compatibility index value between 0.67-1 and could be combined in a consortium as a bio activator. The best P2O5, K2O, and Ca nutrient content is found in the formula of fertilizer with bone meal additives.

Abstract Organic liquid fertilizers (OLF) are made up of essential plant nutrients, as well as beneficial microbes that assist in the recycling of organic waste. The purpose of this study was to determine the macronutrient content of organic liquid fertilizers and compare the growth performance of mustard greens under Wick System hydroponic conditions. Market wastes also known as vegetable wastes, were utilized to produce organic liquid fertilizers and compare it to commercial fertilizer (Nutrient Solution, NS). The vegetable wastes were fermented with water and Effective Microorganisms (EM) Bokashi separately. The ratios used for fermentation are 2 kilograms of vegetable wastes, 0.5 litres of water and 100 grams of EM Bokashi. A parameter study on the OLF and OLF with Bokashi to determine the nitrogen (N), phosphorus (P) and potassium (K) were done. Thereafter, four Wick System (pure water, OLF, OLF with Bokashi and NS) were setup to monitor the growth performance of mustard greens twice a week. The organic liquid fertilizers are produced after 40 days of fermentation and used at a dilution of 1: 10 in the hydroponic system. The OLF and OLF with Bokashi showed the ranges of pH values as 5.1 and 4.6 respectively. The results for the hydroponic system showed that OLF demonstrated the best growth performance. The number and size of leaves and the height of the plants in the NS hydroponic system were almost similar to the plants in OLF hydroponic system. The colour of plants in OLF changed slightly to yellowish green towards the end of the growing season. The life spent of mustard greens in OLF with Bokashi hydroponic system was the least compared to other hydroponic system. This study showed that organic liquid fertilizer is as effective as commercial liquid fertilizer. Considering, it has all the nutrients that plants need to grow.
