The research data shows that 78.8 % of the pasture land soil is eroded. Of this, 14.1 % is water eroded, 58.6 % water-wind eroded and 5.1 % wind eroded. Of the total area of Bayandelger soum, Sukhbaatar aimag, 96.6% suffered soil erosion. Of this, 20 % was moderately eroded and about 10 % was severely eroded. Our research showed that for sandy loams at a depth of 0 - 10cm, the quantity of silt was 21.7%, at 10-20 cm was 22.9% and at 20-30 cm was 25.1%. The decreased quantity of silt on the ground surface shows that soils are sensetive to wind erosion.
