Abstract

The results of studies of optimization processes of nutritional regime and biological activity of soil in the highly specialized grain-potato crop rotation (potatoes – spring barley – peas – winter wheat) for the use of sideratos on sod-podzolic soils of Polissia are presented. The role of sideration in comparison with the traditional fertilizer system in crop rotation with potato crop has been analyzed. It has been found that the alternative fertilizer system – siderate + NPK is not inferior to the indicators (content of NO3, P2O5, K2O) to the traditional system during all phases of crop development. The role of green fertilizers on the balance of biogenic elements, yield and soil fertility indicators has been determined. The use of siderata in intermediate crops will protect the soil from leaching of nutrients in the autumn, as they will be directed to the formation of biomass of the siderate and will help increase yields through the gradual return of the compounds of biogenic elements due to the mineralization of the sideral mass. Agro-climatic resources of the soil-climate zone are more effectively used for the use of green fertilizers, so in modern agriculture, sideration should be considered as an important chain of energy and resource-saving technologies in agriculture. Key words:sideration, organic farming, mineral fertilizers, humus, agrocenosis, nutrients, biogenic elements.
