PRODUCTIVITY OF A CROP ROTATION LINK AND DYNAMICS OF AGROCHEMICAL INDICATORS OF SOD-PODZOLIC LIGHT LOAMY SOIL DEPENDING ON APPLICATION OF VARIOUS KINDS OF ORGANIC FERTILIZERS

Abstract

In research on sod-podzolic light loamy soil an application of various kinds of organic fertilizers in a crop rotation link has provided an increase of productivity of 0,47-1,56 tha-1 f.u., at the general productivity in the fertilized variants of 10,81-11,90 tha-1 f.u. The best indicators of agro-economic efficiency at reproduction in arable layer of sod-podzolic light loamy soil of agrochemical indicators of soil fertility are received in variants with entering of straw manure of cattle of 60 tha-1, 60 tha-1 of peat-manures, and also 40 tha-1 straw manure of cattle in a combination to 5 tha-1 of straw winter triticale on a background of NPK (the general productivity of 11,57-11,90 tha-1 f.u., an increase of productivity from entering of organic fertilizers - 1,23-1,56 tha-1 f.u., full organic-mineral fertilizers - 3,85-4,18 tha-1 f.u., the pure income of application full organic-mineral fertilizers - 466,7-572,2 thousand rbl.ha-1, profitability - 53-68 %).
