Soil erosion on the bottom of hollows in steppe zone of Ukraine

Abstract

Soil erosion, undoubtedly, is one of the main ecological and agricultural problems in the world. Quantity of eroded lands in Ukraine achieves 10.5 millions ha. Annual losses of soil constitutes about 600 millions tons in the country. Gully erosion and other kinds of soil degradation are very extended in east party of Ukraine. Often forming of gullies begin in the links of primary hydro-graphical network, i.e. on the bottom of the hollows. In the countries of the former USSR the application of so-called “measures of constant action” (the soil-protection ground hydrotechnical constructions, runoff-regulating forest shelterbelts and other linear boundaries) are the most recognized way of the soil protection. The aims of this are: 1) to define quantitative indicators of soil loss due to water erosion; 2) to study the soil protection role of MCA on the slopes with hollows.
