SPEADING AREAL OF EROSION PROSES IN THE PSEUDOPODZOILC YELLOW SOILS AND FACTORS THAT CAUSE IT
Description
The erosion prosess was studied in the available pseudopodzolic yellow soils in Lankaran, the spreading areal and factors that cause it were determined in this factor. It was defined that the soil cover was subjected to erosion prosess under an influence of natural and anthropogenic factors. It was determined from our research that a quantity of humus and nutrient reduced 25- 45% in the kinds eroded to their average degree in comparison with the their uneroded kinds, consequently agrophysical, agrochemical and biological characters of soils deteriorated. Erosion in lowland areas is associated with irrigation. As a result, irrigation erosion is formed. It was determined that the zone slope, granulometric and structural composition, coverage percentage, not following the irrigation norms and rules caused formation and development of irrigation erosion.
