ROLE OF THE MAIN FIELD CROPS IN THE ACCUMULATION OF ORGANIC MATTER

Abstract

The results of the long-standing researches (1980-2010) in the stationary experiment on the study of the role of different field crops of crop rotations in the accumulation of organic matter in soil are presented in the paper. The total plant biomass removed with yield (q/ha of dry matter) and remained in soil with roots and crop residues is determined. The share of plant residues (root, stubbles) as percentage of total plant biomass and of the removed yield is shown.
