Study of evolution and fertility of degraded soils in the Kashkadarya river cone spread

\nThis article provides insights into the evolution of degraded soils in the Kashkadarya cone spread and the current factors influencing it. A comprehensive assessment of agrophysical, agrochemical, chemical, and microbiological properties of the degraded pale gray soils is presented, accompanied by the development of agricultural measures aimed at enhancing soil fertility. In the middle and lower segments of the cone, notable variations exist, as highlighted by M.A. Pankov. Flat elevations are characterized by light sandy and sandy soils, whereas the slopes of these elevations exhibit heavy and medium sandy soils. Flat depressions, on the other hand, feature clayey soils. This pattern extends to the bedrock within the soil, where the mechanical composition ranges from sand and loam to heavy sand and silt. In heavy sandy layers, there are occurrences of sand and silt layers and lenses, contributing to the overall mechanical composition.\n
