EFFECT OF CROP ROTATION AND MINERAL FERTILIZER
ON ADDITION OF DENSITY AND POROSITY CHERNOZEMS TYPICAL
UNDER KARACHAY-CHERKESS REPUBLIC

The arƟcle reveals the influence of crop rotaƟon, permanent crop, black steam on such important soil characterisƟcs as the density of addiƟon and porosity. The effect
of the applicaƟon of mineral ferƟlizers on the indicators under consideraƟon is shown. The negaƟve influence of the permanent crop on the addiƟon density and soil
porosity was revealed. The use of a permanent winter wheat culture leads to a deterioraƟon in such indicators as solid density, build density, porosity and increased
soil resistance to crushing. The use of sugar beet in permanent crops also worsens these indicators. The structure of soil aggregates improves with the use of crops of
solid sowing (winter wheat) in crop rotaƟon. The use of black steam leads to a deterioraƟon in these indicators, but to a lesser extent. It has been established that the
use of a permanent crop, the saturaƟon of crop rotaƟon with Ɵlled crops leads to an increase in the density of the solid phase of the soil, which oŌen goes beyond
the opƟmum limits of most crops. The use of black vapors in condiƟons of sufficient moistening leads to over-consolidaƟon of the soil, so it is not jusƟfied. The use
of permanent culture leads to a deterioraƟon of almost all the physical and mechanical properƟes of the soil, but the use of ferƟlizers parƟally neutralizes this effect.
Keywords: soil, the solid phase density, bulk density, porosity, minimizing processing, crop rotaƟon, permanent crop.
