Soil nutrients losses of eroded black soil in Northeast China

摘要：

Soil nutrient loss from eroded Black soil in Northeast China, is one of the limiting factors affecting soil fertility and environment. Field experiment with No tillage ( NT), Reduced tillage (RT), Conventional tillage (CT), Vegetation restoration (VR) and Bare soil (Bare) treatments were carried out on a sloping farmland of 5°from 2008 to 2009 in Hailun station, Heilongjiang province, typical Black soil region. Total Nitrogen (TN), Total Phosphorus (TP), Ammonium Nitrogen (NH4 + -N) and Nitrate Nitrogen ( NO3 --N) by runoff and subsurface flow (in depth of 0 -100 cm), respectively were measured in consecutive two years. The primary results were as follows:
