SPEADING AREAL OF EROSION PROSES IN THE PSEUDOPODZOILC YELLOW SOILS AND FACTORS THAT CAUSE IT

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.
