on-conventional sight at parameters of optimum structure of arable layer

Abstract

The purpose. To inform about results of own researches and reflections concerning opportunities of physical parameters of soil by means of measures which in the core remain without attention or are evaluated negatively. Special attention is given to an opportunity of optimization of water regime. Methods. Field, laboratory-field small-plot experiments, laboratory researches. Results. Essential influence of cloddy and fissured structure of soil on physical and agronomic soil characteristics and availability in field and space localization of organic mass of the postharvest remnants of different structure of mineralization is fixed, as well as features of influence of micro-relief of surface of a field upon heterogeneity of density of soil in connection with size and quality of yield, in particular tuber crops, and facts and conditions of development of positive influence of cloddy and fissured constitution of arable layer upon secure with moisture and productivity of field crops. Conclusions. Use of subsoiling technique secure saturation of the upper (sowing) layer of soil with organic mass of postharvest remnants which changes its agro-physical and agronomic properties, prevents formation of surface crust and depending on crop and period of sowing influences field germination rate of a crop.
