Aim. To study the impact of perennial grasses mixtures on the formation of erosion resistance of
soils of different degradation degree and their unmodifi ed analogues in conditions of long-term
experiment. Methods. Field, laboratory, assessment and comparison. Results. It was established that
cereal grass mixtures increased erosion resistance of slope soils considerably within fi fteen
years. The sum of
soil structural aggregates was improved from satisfactory into good category. There were positive
the number of water-resistant aggregates as well. The studies confi rmed a positive impact of
the density and porosity of soil. Soil density was the lowest when the slope was laid down in
and its mixture with cereal grasses. The intensifi cation of soil erosion and the approximation of
horizon level to the surface resulted in the compaction of upper soil layers to 1.29–1.44 g/cc.
of soil correlated with its density which did not exceed optimal values in poorly eroded soils in
The studies proved the impact of the ways of laying down the slope in grass and the level of soil
on its humidity and water permeability. In the experiment conditions, the increase in soil
degradation led to
the decrease in its moisture. The decrease in the content of humidity in crop fi eld took place at
of higher intensity of the growth and water consumption of lupine-cereal grasses in comparison with
mixed herbs, especially in the periods with a small amount of precipitation. The difference in the
layers was in the range of 0.2–0.5 %. It was established that the highest values of soil water
formed on lupine-cereal grass mixtures in all the variants of degraded soils. Conclusions. Laying
lands in perennial lupine in combination with cereal grasses promotes the formation of their higher
to erosion processes and restoration of fertility. Perennial legume-cereal mixtures ensure the
structural-aggregate state, total density and porosity of soil, enhance its water supply and water
gray forest soils, degradation, erosion resistance.
