Abstract	To calculate the soil loss tolerance for chernozems of the central chernozemic region, a linear modification of Skidmore’s equation was used. The soil loss tolerance values were obtained with due account for the soil type, the degree of erodibility, and the crop rotation pattern. The maximum possible value (10 t/ha per year) was obtained for a typical noneroded chernozem in all the crop rotations. Close values were obtained for noneroded leached and typical chernozems (9.6–9.9 t/ha per year depending on the crop rotation pattern). The soil loss tolerance for the noneroded podzolized chernozem was somewhat lower: 9.1 t/ha per year in the grain-herb-intertilled crop rotation and 6.3 t/ha/year in the grain-intertilled crop rotation. With an increase in the degree of the soil erosion, the soil loss tolerance decreased in all the variants of the experiment with an especially abrupt decrease in the grain-intertilled crop rotation (from 9.9–10.0 to 0.3–2.0 t/ha per year in the, respectively, noneroded and slightly eroded ordinary and typical chernozems). In the grain-herb-intertilled crop rotation, these differences were much smaller: in the slightly eroded typical chernozem the soil loss tolerance was estimated at 9.7 t/ha per year, while, in the slightly eroded typical chernozem, at 8.1 t/ha per year. The moderately eroded chernozems without the addition of manure could only be used in the grain-herb-intertilled crop rotation; the soil loss tolerance was estimated at 9.0 t/ha per year for the typical chernozem and 4.3 t/ha per year for the ordinary chernozem.
