Significant land areas in Kazakhstan have been taken out of agricultural use, leading to large tracts of fallow land. If left unmanaged, these lands can become infested with weeds, deteriorating the phytosanitary condition of the region. Fallow lands also play a role in restoring soil fertility and represent a reserve for agricultural use. The study aimed to analyze the influence of tillage methods and cultivation technologies on the productivity of dark chestnut fallow soils in northwestern Kazakhstan. Field experiments were conducted from 2018 to 2022 on dark chestnut-heavy loam soils. The study included the analysis of soil properties, including moisture content, density, nutrient availability, and biological activity. The effectiveness of soil tillage methods was assessed through the cultivation of spring wheat and perennial grasses, using a three-factor experimental design with three replications. The primary tillage methods compared were deep plowing, chisel plowing, and shallow loosening. After 8 years, observations showed that, fallow soils become close to virgin soil. However, their water regime becomes unfavorable. Deep moldboard and boardless tillage on black fallow soil served as most appropriate agricultural and technological practices to improve water regime, soil compaction, crop yield, and soil structure in this arid region.
