Scientific and technical support of animal by-product industry

Animal by-products are additional outputs of the main farm production. They should be integrated into the closed cycle of agro-ecosystems to restore the fertility of farm land. The aim of the study was to develop a comprehensive approach to the use and pre-application treatment of manure in the form of animal by-products. The study analyzed the current challenges in the processing and application of animal/poultry manure as organic fertilizer in different regions of the Russian Federation. The authors analyzed the quantity and quality of animal by-products, technologies and equipment available in the regions, laws and regulations relating to the assessment of the man-made environmental impact, and the state of environmental monitoring. The study found that the annual volume of animal by-products formed in agricultural organizations and available for processing and fertilizing application was above 250 million tons. While the use of organic fertilizers in 2022, for example, amounted to only 70.3 million tons. This could be due to the lack of equipment and technologies in agricultural organizations, and the underdevelopment of the animal by-product industry. The authors believe that the considered industry should apply the best available manure processing technologies, high-tech engineering systems, digital monitoring of production processes, and intelligent digital tools for on-farm environmental control. This list may also include adaptive measures of economic support for agro-ecological activities and relevant eco-standards for environmentally safe technologies, machines and equipment. The above proposals will add at least 350 million tons of high-quality organic fertilizers to domestic agricultural production and reduce the negative balance of nutrients by at least 2000 thousand tons of NPK
