Abstract

The chemical properties of soils common in the Muzbulok massif of the Bakhmal district of the Jizzaz region have changed due to climate change and anthropogenic impact. Negative phenomena such as a decrease in the amount of humus and nutrients are observed in these soils. The humus content in the arable layer of the field sown with perennial alfalfa in the studied crop rotation system was 1.117%, total nitrogen - 0.067%, total phosphorus - 0.40%, total potassium - 1.172%, in perennial wheat (monoculture) humus was 1.117%, nitrogen - 0.070%, phosphorus - 0.35%, potassium - 1.050%. Low- and medium-nutrient groups were formed with 10.6 and 10.8 mg/kg available nitrate, 35 and 30 mg/kg phosphorus, and 211 and 202 mg/kg exchangeable potassium, respectively.
