SAPROPEL INFLUENCE ON THE PRODUCTIVITY LEVEL OF CROP ROTATION LINK AND SOD-PODZOLIC SANDY LOAM SOIL FERTILITY

Full Text:

Abstract

Comparative effectiveness of application of organo-calcareous and siliceous sapropel and cattle manure in the crop rotation link maize - spring rape - winter triticale was studied at the sod-podzolic sandy loam soil. It was found that application of 40 t/ha of organo-calcareous and 45 t/ha siliceous sapropel in the crop rotation link on the yield effect was similar to the effect of 60 t/ha of cattle manure and provided productivity growth of 29.6 and 33.2 c feed units/ha in the variants with organic-mineral fertilizer system.
