STUDY OF THE PROCESS OF MECHANICAL AND CHEMICAL ACTIVATION OF BROWN COAL OF THE ANGRENSK DEPOSIT AND PHOSPHORITES OF THE CENTRAL KYZYLKUM

Abstract

One of the problems of agricultural production is associated with soil humus, which is the basis of the fertility of any soil. The irrigated soils of our region contain very little organic matter. In terms of the amount of humus, they are in the last place among other soils. One of the sources of organic matter replenishment in irrigated soils can be brown coals, coal-humic fertilizers based on them.
