Nutritionally unbalanced organic waste can be converted into potential resources for animal and plant farming by culturing black soldier fly (Hermetia illucens) larvae (BSFL) and prepupae (BSFP). BSFL and BSFP are rich sources of protein and lipids, while the leftover excrement called “frass” can be used as an organic fertilizer. Using readily available resources, BSFL were cultured on spent coffee, donut dough or an equal blend for 35 days. Survival, productivity, daily pupation and biochemical composition of BSFL and BSFP were measured along with the nitrogen-phosphorus-potassium values of the frass. Survival was highest in the blend compared (81%) to spent coffee (45%) or dough (24%); however, BSFL and BSFP were significantly longer and heavier from dough. Stage and food significantly influenced the protein, lipid and glycogen content of the BSFL and BSFP, which tended to be higher in the latter. While fatty acids were often significantly higher in BSFL fed spent coffee, the amino acid composition of BSFL was generally higher in dough. Frass from the blend had significantly highest nitrogen content, while potassium and phosphorus were significantly higher and lower from spent coffee, respectively. Although coffee and donut dough were suboptimal substrates for BSFL, a blend of these produced BSFL and frass that were nutritionally comparable to soybean meal and many organic fertilizers, respectively.

Fertilization is an action in plant care. Fertilization provides additional nutrients for the soil. Fertilization has a large influence on plant growth and production. Fertilization consists of organic and inorganic fertilizers. Both of these fertilizers must be balanced so that the nutrient content can be maintained properly. The use of fertilizers an organic fertilizer that is widely used, but the use of chemical fertilizers on an ongoing basis will reduce the level of soil fertility. This must be balanced with organic fertilizer. One of the organic fertilizer is guano fertilizer. This fertilizer is fertilizer made from animal waste, namely bats. This fertilizer has a very good content including nitrogen, phosphorus, and potassium. Knowledgethis fertilizer will still be low, so that an introduction and practice about guano fertilizer is needed. Therefore a community service activity was carried out on the development of the manufacture of guano fertilizer. Guano fertilizer development is carried out in the form of granules (granules). The targets of this service are vocational students who are related to agriculture. Vocational students are selected as the young generation to know about organic fertilizers and are able to contribute to the implementation of the agricultural industry. Community service activities were carried out with a presentation of the theory and practice of making guano fertilizer. As a result of this activity, students learned about organic fertilizer, namely guano fertilizer and its contents, nutrient content in the soil, balance in maintaining nutrient content in the soil, the practice of making guano fertilizer, and the creation of granule form from guano fertilizer.

Overuse of chemical fertilizer has led to severe land degradation and environmental pollution in China. Switching to organic fertilizer may improve soil quality and reduce pollution, which is meaningful to the sustainable development of Chinese agriculture. This study examines how farmers’ perceptions and risk preference affect their organic fertilizer investment using a representative rural household survey from Guangxi, a major agricultural region in China. Tobit and double-hurdle models are used to empirically test their impacts on organic fertilizer adoption and investment. An ordinary least squares model is used to regress chemical fertilizer use on the same set of explanatory variables to compare and contrast farmers’ different fertilizer investment behaviors. It is found that both organic fertilizer perceptions and risk attitude significantly affect organic fertilizer investment. Perceived yield-increasing and quality-improving effects encourage organic fertilizer investment, while perceived cost increases discourage it. Moreover, risk-averse farmers are more likely to invest in organic fertilizers. Most of the perceptions affecting organic fertilizer investment have an opposite impact on chemical fertilizer investment, which suggests substitutability between organic and chemical fertilizer. Interventions that aim to improve farmers’ perceptions of organic fertilizer and illustrate its risk-reduction effect could be effective in promoting organic fertilizer use, which can help achieve China’s sustainable development of agriculture.

This article deals with comparison of composts and manure use from the viewpoint of handling, transport and application on agricultural land. The published values were established by measurements under working conditions and afterwards converted on the basis of the content of nutrients defined in laboratory. Compost contained a greater share of nitrogen, phosphorus and potassium and had higher dry matter content and lower volume weight. Direct consumed energy expressed by recalculation of the consumed diesel fuel in case of composts moved from 5.12 MJ/kg (potassium) up to 16.19 MJ/kg (phosphorus). In case of manure it was higher and moved from 10.49 MJ/kg (nitrogen) up to 29.79 MJ/kg (phosphorus). The greatest share in energy consumption occupies transport, which was considered uniformly at the distance of 5 km. The study confirmed the feasibility of use of compost in agriculture as a partial substitute of conventional organic fertilizers; for its handling, transport and application the standard mechanization used for manure may be utilized.

The low quality of Entisol is caused by low availability of nitrogen, phosphorus, and potassium as well as low soil pH, so the addition of vermicompost is necessary. The purpose of this study was to determine the effect of vermicompost application on soil quality and to obtain the highest vermicompost dosage on the availability of nutrients such as N, P, K, and the yield of corn. The field experiment used a Randomized Completely Block Design (RCBD) with 7 dosages of vermicompost and three replications. The treatments were V0 = 0; V1 = 5; V2 = 10; V3 = 15; V4 = 20; V5 = 25; V6 = 30 Mg ha-1. Variables observed consisted of 1) initial soil and vermicompost characterization analysis, 2) soil analysis and N, P, and K content in leaves, and yield of corn. The results showed that Entisol was classified as low quality; however, vermicompost quality complied with the requirements of quality organic fertilizer. The experiment also indicated that the highest pH of Entisol (5.31) and K content in corn leaves (2.12%) were obtained at a dose of vermicompost 25 Mg ha-1. Meanwhile, the highest weight of husked corn cobs (415.55 g plant-1) and weight of unhusked corn cob (351.11 g plant-1) were obtained at a vermicompost dose of 15 Mg ha-1.

Fertilizer Use

Granular organic fertilizers have been increasingly used in agriculture due to the longer delivery of nutrients to plants and the milder impact on the environment. The aim of this study was to determine the energy, environmental and economic efficiency of granular and non-granular organic fertilizers. Four technological scenarios of organic fertilizer use were used for comparative assessment: (1) manure fertilization (16.0 t ha−1), (2) manure fertilization (30.0 t ha−1), (3) manure pellet fertilization (2.0 t ha−1), and (4) fertilization with meat and bone meal pellets (0.7 t ha−1). Experimental studies using the mass flow method of laser spectroscopy were performed to evaluate the comparative environmental impact of granular and non-granular organic fertilizers. Economic assessment was performed for mechanized technological operations of loading, transportation and distribution of organic fertilizers, estimating the price of aggregates used and fuel consumed, the costs of individual technological operations and other indirect costs. The results showed that for mechanized technological operations, when fertilizing with granular organic manure and meat and bone meal fertilizer, energy consumption is 3.2 to 4.0 times lower compared to fertilization with manure. The average ammonia (NH3) emissions from granular organic fertilizers were found to be six times lower than from non-granular organic fertilizers. The lowest costs for mechanized works were incurred when using meat and bone meal pellets, the highest economic benefits of organic fertilizers by elements was when using manure 30 t ha−1, and the highest costs for organic fertilizers were incurred when using manure pellets.

The article is devoted to the development of a technology for obtaining organic fertilizers from poultry waste based on biocatalytic processes. Currently, many poultry farms have become sources of environmental pollution, thereby causing serious environmental problems and economic and social damage. The problem of reliable protection of the natural environment from pollution by bird droppings is currently relevant. In the area of operation of large poultry farms, air pollution by microorganisms, dust, foul-smelling organic compounds, which are decomposition products of organic waste, as well as nitrogen, sulfur, and carbon oxides, is possible. Bird droppings contain acids, nitrogen, phosphorus and potassium, heavy metals. The content of nitrogen, phosphorus and potassium changes dramatically depending on the quantity and quality of the feed. Humic substances isolated from brown coal have a sufficiently high sorption activity and are used as cheap sorbents for solving a number of environmental problems in industry. These studies are aimed at minimizing the main disadvantage of the anaerobic digestion process, the low reaction rate, which leads to the need to create large-volume bioreactors. On the basis of the research carried out, a technology has been developed for obtaining organic fertilizers from poultry waste by the method of anaerobic fermentation of chicken manure with humidity at a temperature of 27 °C - 50 °C with the addition of sodium humate. The resulting fertilizer is intended for use in agricultural production, horticulture, floriculture, forestry, municipalities, in household plots in order to increase the yield and quality of crop production. For the developed technology, an application has been submitted for obtaining a Patent for the invention of the Republic of Kazakhstan «Method for producing organic fertilizers» (priority No. 2021-22818, dated July 13, 2021). The invention allows to significantly reduce the time of fermentation, to enrich the product with organic and mineral products contained in sodium humate, to convert the salts of heavy metals into an insoluble state, to improve the environmental friendliness of the method.
