Man made accelerated erosion is a key reason for soil nutrient loss after forestlands were disturbed by human being. Sloping spatial distribution of soil nutrient loss responds to spatial distribution of soil erosion patterns erosion intensity. Shallow gully ditch is the severest position of soil nutrient loss. Soil nutrients abruptly loss in the beginning stage of forest removal. After five years of forest removal, soil nutrient content reduces by 50%. A layer loss in soil profile is a sign of soil nutrient loss.
