ECONOMIC AND ENERGY EFFICIENCY OF THE RESTORATION SYSTEM OF RADIOACTIVELY CONTAMINATED SOD-PODZOLIC SOILS AGROECOLOGICAL FUNCTIONS

M.Yu. Tarariko

Abstract


Today agriculture is characterized by narrowing of specialization, introduction short crop rotation, reduced volumes of mineral fertilizers and by-products plant involvement as organic fertilizer, in the absence of manure. In this connection there is a set of urgent issues of economic and energy efficiency evaluation of different agri-environmental soil functions restoration systems. In the systematic use both traditional and alternative restoration systems, with organic fertilizers, especially when plowing low value harvest part, humus content increased, that accordingly had a positive impact on soil energy intensity – 17-23 GJ / ha. Hence, the eco-energy and economic analysis showed that both traditional and alternative of soil system restoration should be encouraged for production depending on the production specialization. That is, when livestock specialization traditional system is to be introduced and with plant growing – an alternative one.
