Abstract:
　 Present studies investigated the effects of artificial topsoil removal on soybean dry matter accu-mulation and yield in a black soil field with 6°slope and 30 cm topsoil layer. Dry matter accumulation wasnot affected when 10 cm topsoil was removed, and significant reduction was observed while topsoil removalexceeded 10 cm. Seed yield was only reduced at 3. 1 %and 3. 2 %by 5 cm and 10 cm removal ,respective-ly , while 33. 2%and 59. 2% reduction was observed in 20 cm and 30 cm removal treatment. It indicatedthat soil erosion will result in a serious yield reduction in soybean, and manure application could alleviatethe yield loss.
