Сirculation of carbon oxide depending on the energy efficiency of agriculture – regional aspect

Aim. To establish the relationship between energy efficiency of crop production with balance carbon monoxide during period increasing manure application (1956–1995) and its replacement by by-products as organic fertilizer to develop a model agrocenosis depending on costs in agriculture. AIC Cherkasy region from 1956 2020. Methods. Information-analytical, mathematical-statistical (correlation-regression, factor, method nonparametric statistics). Results. The increase agriculture region's agro-industrial complex is associated decrease formation humus fertilizers, when Kee per unit was accompanied 0.16 million tons an mineralization (Kee 2.42 million. C-CO2 mineralization). During supplementation root residues, ratio С-СО2, which passed residues range 0.7–1.2 1, but due higher level humification coefficients more intense source emissions compared are stock factor C-CO2. With complete side phytomass fertilizer, emission excess remains lower average 2.27 times application. Conclusions. growth Kee, mineral processes increases sequestration capacity С-СО2 decreases (according Ib agrocenosis), agricultural productivity increases, fertility lands decreases, typical for When replaced by-products, decrease, provides conditions land against background reduced productivity.
