The erosion process effect on the physical-chemical properties of grey-brown soils in Mountain Shirvan

In the article, the influence of the process of erosion on the physical and chemical properties of soil in Nagorny Shirvan is shown. In non-eroded soils, the main place among cations is occupied by Ca2+ cation, Mg2+ cation is much smaller than it, and Na+ is very insignificant. As the degree of erosion increased, the amount of Ca2+ cation decreased. No drastic changes were observed in the Mg2+ cation. The Na+ cation increased as erosion increased, which in turn leads to soil compaction. The value of pH shows that the alkalinity of the soil actually increased without the development of erosion. This led to some weakening of soil fertility.
