In a course of the research there was studied the humidity ranges of arable horizon of sod–podzolic soils with different erodibility degree of Belarus (according to data of 10-year study at the experimental stations). The research was realized in the conditions of the Republic of Belarus on moraine and loess loam in Vitebsk and Minsk region. As a result of research it was revealed average moisture content of the arable horizon of sod-podzolic soils with different erodibility degree formed on loess and moraine loams, as well as ranges of their deviations. In the spring period humidity of arable layer of sod-podzolic soils on loess loams was 20–30% (level FC) in more than 70% of the cases, and during the harvest the most probable values were of 15–20%, which corresponded to the humidity rupture of capillaries (HRC). At the beginning of the growing season arable layer moisture of sod–podzolic soils on moraine loam was below field capacity (15–20%) in 50–70% of cases, and at the end of the growing season it was at the level of HRC (10–15%) in 43–71% of cases.
