Global climatic changes have caused an increase in the severity, frequency and duration of extreme precipitation, which increases the risks of erosion of agricultural land as a result of an increase in the share of surface runoff. Under laboratory conditions, an assessment was made of the rate of runoff and the intensity of erosion of monolithic soil samples taken from three closely located plots that differ in the method of land use: with classical tillage, No-Till, and virgin lands. The experiments were carried out on a sprinkler with a set irrigation level corresponding to a natural heavy rainfall for 30 minutes at three slope angles: 1°, 3° and 7°. The highest degree of soil washout was found in samples with classical tillage, and the lowest in virgin lands. The susceptibility to water erosion of soils with No-Till treatment strongly depends on the slope angle and decreases significantly with its increase but has higher values than for soils with classical treatment. Depending on the slope angle, soil erosion resistance with No-Till is 3.6 times lower than for virgin lands and 4.2 times higher than for classical tillage at 1°, 3.6 times lower than for virgin lands and 8.2 times higher than for classical processing at 3°, and at 7°– 9.3 times lower than virgin soil and 4.2 times higher than classical treatment.
