The creation of sown grass stands on erosion-prone lands improves the agrophysical properties of the soil, curbs degradation processes, and contributes to increasing their sustainability. The research on the effect of agrophytocenoses on the anti-erosion resistance of soils was laid in the summer sowing period in 2020 on a slope (3-8°) of the Pre-Carpathian Department of Scientific Research of the Institute of Agriculture of the Carpathian Region of the National Academy of Agrarian Sciences. The goal was to determine the effect of multi-component perennial grass mixtures on the anti-erosion resistance of weakly and moderately washed sod-podzolic soils. On the basis of the obtained research results, it was established that higher reserves of productive moisture, higher total pore density, the content of air-dry agronomically valuable aggregates, the number of water-resistant aggregates on lightly washed and moderately washed soils were noted under 7-12-component grass mixtures compared to three-component grass mixtures. Soil washout was 0.55–0.75 m3 on lightly washed and 0.85–1.40 m3 on moderately washed soils. It was noted that the erosion process is inversely related to the density of the grass stand.
