EFFECT OF EROSION PROCESSES ON SOIL PROPERTIES

Today, global climate change, along with drought, the processes of soil degradation are becoming one of the urgent problems for scientists all over the world. In this regard, a number of works are being carried out in Uzbekistan. According to the National Report on the State of Land Resources of the Republic of Uzbekistan, only 10% (4.3 million ha) of the 44.9 million hectares in the Republic are irrigated. About 2 million hectares (45%) of these lands are subject to secondary salinization. There are problems with water erosion on 800,000 hectares and wind erosion on 2 million hectares. The object of the study is dark serozem soil belonging to the region of mountain and sub-mountain soils, formed under complex climate and relief conditions. morphological characteristics of these soils in the profile, changes in some properties of these soils according to different exposures and slopes of the slope, including non-eroded watershed, moderate and strongly eroded transit, and corresponding changes and washing in washed-accumulated horizons information on monitoring processes is given.
