The purpose of research is to develop models that will ensure the optimal level of biologization of agriculture, taking into account resource conservation: nutrients, humus, moisture, and trace elements in accordance with the zone of Polissya. Research methods: stationary lysimetric and stationary field experiments; laboratory (chemical analysis of soil and plant samples and lysimetric waters); comparative calculation and statistical method. The essence of work: modeling of agrotechnology for optimization of balance of macro-, meso-, microelements, search of reserves of organic fertilizers, regulation of intrasoil runoff of moisture and losses of nutrients due to agrotechnical receptions. To achieve this goal solved the following tasks: - to investigate the amount of nutrients in the soil and the loss of nutrients from different types of fertilizers; - to establish patterns of migration of macro-, meso- and microelements in the system "soil-fertilizer-plant"; - to establish indicators of intensity of balance of macro-, meso- and microelements at traditional, mineral and alternative systems of fertilizer. On the basis of researches the model of management of a cycle of biogenic elements at the expense of use of alternative system of fertilizer NRK + by-products + green manure + a microbic preparation + liquid complex fertilizer "BioMAG" is created. The model provides growth of conditionally net profit by 2081 UAH or 36% from 1 hectare and the level of profitability of agricultural production. products by 76% compared to the mineral fertilizer system.
