INTENSIVE METHODS OF COMBATING THE DEGRADATION OF GRAY SOIL

Abstract

Under increasing anthropogenic pressure and changing climatic factors, the problem of sierozem soil degradation is becoming particularly relevant for arid agricultural regions. One of the urgent problems in cotton growing in the turkestan region is the fight against the degradation of irrigated lands and the improvement of the meliorative state of the lands of cotton plantations, based on the use of soil-resource-saving technology for growing cotton, based on the rational use of high-tech organo-biological ameliorants that help prevent degradation processes in the conditions of progressive dehumification of soils.

 It was revealed that the use of organo-biological fertilizers against the background of land reclamation shows greater intensity in improving the meliorative conditions of gray soils. According to the results of the research, it was established that due to the use of organic ameliorants, it was revealed that the process of humus formation in the soil proceeds intensively, this is improved by using biomeliorant for primary soil cultivation at a rate of 3.5 tons/ha and by chiselizing the soil at a rate of 0.5 tons/ha, i.e. It was determined that the humus content in the 0-20 cm soil layer was 0.825%.

The main objectives of our research are to develop methods for improving the agro-ameliorative conditions of irrigated sierozem soils, based on the use of organo-biological fertilizers. In addition, an important question posed before the study was the possibility of replenishing the soil with organic matter and ensuring a deficit-free humus balance.
