Formation of a model of a closed production cycle in an agricultural enterprise based on the use of biological waste

Abstract

Abstract An ecologically safe agroecosystem can be thought of as a model of a closed cycle of matter and energy. Increasing the adaptive potential of the production system is achieved by creating flexible production facilities, improving infrastructure, as well as researching and preparing new types of raw materials, energy and technologies for inclusion in the production cycle. The use of an ecological-economic model, in the form of a computer program, will allow, using dynamic mathematical functions, combined into a structure according to the feedback principle, to process a large amount of information about the current state of production sectors, predicted climatic parameters, dynamics of market prices, etc. The result is a tactical modernization of production to ensure maximum sustainable profitability and environmental safety. The introduction of vermicompost into the soil, at a dose of 8-12 t/ha, provides a return of carbon to the agroecosystem (280-330 kg), which compensates for the losses of the humus mineralization process (285 kg) during the cultivation of grain crops, for example, spring barley, with a planned grain yield of 2.0 t/ha. The field of application of the model can be peasant and farm enterprises, state agricultural enterprises, regional departments of agriculture with the possibility of regulating the social and agricultural policy of the region.
