Influence of Buckwheat Sideral Agricultural Communities on the Agrophysical Properties of Soil Resources of the Chernozem Zone

Abstract

In the field experiment, the influence of binary sideral buckwheat mixtures on the bulk mass, structural coefficient and degree of aggregation of arable and sub-arable horizons of typical heavy loamy chernozem was studied. It is shown that mixing of crops in sideral agricultural communities in most cases led to an increase in the yield of subsequent grain crops and an improvement in the considered agrophysical properties. The most significant positive effect on the agrophysical properties of both arable and sub-arable horizons, as well as on the increase in the yield of grain crops, had an agrocenotic effect in binary mixtures of buckwheat of the Demeter + sunflower variety and buckwheat of the Winged + sunflower variety. In the variants in the soil under the agro-communities soy + buckwheat of the Winged variety and buckwheat of the Demeter + buckwheat of the Winged variety, on the contrary, there was a slight improvement in these indicators, and sometimes their deterioration in both horizons.
