Contradictory data about impact of the minimum and zero cultivation on physical properties of southern chernozems (Chernozem) of heavy particle size distribution have caused the necessity of their studying on the territory of Akmola region. Researches of physical properties of southern carbonate chernozems were conducted based on comparison of soils physical properties the virgin site with pilot allotments of deep and minimum cultivation of land, direct crops and zero technology. Reduction of content physical clay particles and silt in comparison with the virgin site revealed in the upper layer of 0-10 cm in case of all above-stated handlings. Mechanized conversions cause the activation of profile differentiation with regard to silty fraction. Descending migration from the arable horizon to subarable horizon happens in case of deep cultivation of land. This migration from layer of 0-10 cm to underlying arable layer of 10-26 cm happens in case of minimum and zero cultivation of land. The greatest deterioration in addition density of plougland in a layer of 0-10, 10-20 and 20-30 cm observe in case of the minimum and zero cultivation of land.

Using the thermal method and IR spectroscopy, a typical chernozem (Haplic Chernozem (Loamic, Pachic)) of various land uses was studied. According to the data obtained, the organic matter of the chernozem mainly consists of weakly thermally stable aliphatic compounds such as polysaccharides. This is evidenced by the mass loss in the low-temperature region, which varies within 68.15–71.54%, and the intense absorption band at 1083 cm-1, which determines the shape of the IR spectra of the chernozem. Under the influence of extensive agricultural use, the mineralization of labile aliphatic compounds and an increase in stable cyclic structures in the composition of the organic matter of chernozem occurred. This is indicated by a decrease in the Chernikov–Konchits Z coefficient from 3.16 to 2.47–2.73 and the intensity of most absorption bands in the IR spectra. The most noticeable negative impact on the organic matter of a typical chernozem was caused by bare fallow.
