Operator model to control process of obtaining vermicompost

Currently, in the Russian Federation, the amount of contaminated agricultural land is about 2.4 million hectares. The economic damage resulting from the violation of regulations related to the use of bedding manure in animal husbandry is estimated at an average of 150–170 million rubles/year. For the sustainable development of agrolandscapes, integrated biotechnologies should be developed that can fully process the agricultural waste into organic safe fertilizers throughout a year. A technology has been developed for the production of complex fertilizers by mixing waste, and turning it into an organic fertilizer. Integrated biotechnology provides a consistent mixing of pig waste, alcohol production and organic residues in the form of winter crops. It provides processing of the solid phase of pig manure, which is the main component of the liquid fraction of alcohol waste (bard), providing the process of maintaining the moisture content of the substrate and winter wheat straw. The result of complex biotechnology is biohumus (biocompost), obtained from pig pig compost and fugata. A red Californian worm is used as a compost processor in the biocompost. The physicochemical composition of the solid fraction of pig manure and irrigation water has been investigated for the composting process. It is established that components of the technology contains a high level of nutrients, especially macroelements, and do not contain hazardous substances for the nutrition of worms. Therefore, the development of integrated biotechnology is based on processes and parameters of accelerated waste processing and their utilization in the form of organic bio-fertilizers. An operator model has been created to control the process of obtaining vermicompost, , which is based on technological lines for processing waste into organic fertilizers, and their utilization to improve the sustainability of agricultural landscapes. The operator model allows us to manage biocomposing on production lines, each of which completes the process and the output is a complete product to use. On the main line, the organic fertilizer comes ready for utilization on agricultural landscapes. To increase the fertility of agricultural land, additional income from biocomposting is necessary.
