erosion and nutrient loss in Heibeishan watershed from May to August in 2009 and 2010 were studied.Results indicated that runoff
erosion
and nutrient loss from runoff plots under natural rainfall condition had a certain similarity.They were in the decreasing order of bare land
ridged-furrow
contour listing
film mulching
and equal-height deep loosening.Compared with the bare area
the conservation tillage could reduce runoff by 29.8%~63.3%
soil erosion by 64.6%~96.6%
nitrogen loss by 54.0%~89.5%
and total phosphorus loss by 49.4%~92.2%.This suggests that conservation tillage can play very good roles in conserving soil and water and reducing nutrient loss.
