In the face of fierce competition and current sanctions, Russia's food independence is becoming of great strategic importance. The main supplier of food raw materials to provide our country with food is agriculture. The main branches of agriculture include crop production, animal husbandry and processing of agricultural products. Each of the industries faces problems that reduce their competitiveness in the production process. The branches of agriculture are interconnected, so combining them into a system will allow you to trace and optimize the links between them, and solve some problematic issues, primarily environmental and economic. The purpose of the study is to substantiate the process of deep processing of manure as an element of the subsystem of agricultural production in the overall system of strategic economic independence of the country. The methods of system analysis and system synthesis were used in the work. Also, to create a model describing the parameters and properties of the process under study, the modeling method was used in the work. A model of the technological process of obtaining, processing liquid manure and using the obtained organic fertilizers has been developed. The model describes the links between the technological processes of growing farm animals, processing liquid manure and the production of crop production. When constructing the model, the latest developments in the field of cleaning and disinfection of all types of manure have been applied, allowing to reduce environmental damage as a result of the use of renewable energy sources and environmentally sound modern technologies in some of them. The use of the proposed technologies will increase the economic effect in the process of obtaining and applying organic fertilizers. The developed model makes it possible to optimize forward and backward connections between technological processes, reduce the time of individual operations and coordinate the input and output parameters of previous and subsequent operations.
