INVESTIGATION OF APPLICATION OF BIOMELIORANTS WITH MAGNESIUM ON THE BASIS OF LOCAL NATURAL AND MAN-MADE RAW MATERIALS TO ECOLOGICALLY DISTURBED SOILS

Abstract

Fertilizers, ameliorants, or soil additives should be applied during the reclamation of ecologically damaged areas due to the lack of organic substances and nutrients necessary to restore the soil-vegetation layer. One of the current trends in land reclamation is the use of non-traditional fertilizers (ameliorants) formed on the basis of silty sediments of water treatment plants. The purpose of the work is to analyze the efficiency of using biomeliorant obtained from the silty sediments of water treatment plants, straw of cereal plants and ground dolomite mineral mixture with diluted sulfuric acid solution for the restoration of damaged soils. The effect of applied biomeliorant on the physico-chemical properties and productivity of saline soils. It is known that pomegranate ground dolomite is considered a valuable ameliorant. It is a proven fact that liming the soil with it has a positive effect on the water-physical properties of the soil and the productivity of agricultural plants. Adding dolomite, which is widely used as a mixed-mineral fertilizer, to the silt-straw system has a positive effect on the activity of biogenic elements. Even a slight increase in its amount improves the physical and chemical properties of the soil and the water absorption capacity for the full activation of the system.
