The study of soil physical properties is a theoretical and practical basis for choosing of a cultivation system. It is an important agri-acceptance of modern agriculture. In the scientific literature, many publications in periodicals is devoted to the study of soil physical properties. In this paper are shown features of study of physical parameters of soils on southern chernozem, which characterized by low-humus content under different cultivation systems for corn: plowing, chisel, No-till and grassland are highlighted. The methodological features of the research are described in detail in the paper. Determination of physical parameters for different soil tillage systems showed that the five-year application of No-till for maize significantly improved compared with the plowing, the structural composition of the southern chernozem was 62.4–66.6 %, and the aggregates had a rounded form with pronounced porosity. Soil density was also optimal within the range of 1.10–1.26 g / cm3, which gives grounds for positively assessing the investigated agriculture measure and the possibility of its introduction into production.
