Abstract: The content of nitrate-N, available-P2O5 and available-K2O in the soil under no-tillage maize cropping through microplot trial was studied. The result showed that the content of soil nitrate-N, available P2O5 and available K2O decreased under no-tillage condition compared with conventionanl tillage. Among these, the content of soi lnitrate-N was most significant ly affeted. The content of available P2O5was affected secondly. The least affeted nutrition was available K2O. The content of soil nitrate-N under no-tillage was 15.3%- 51.2% lower than that of the conventional tillage in 0- 20 cm, and 4019%- 4617% lower in 20- 40 cm.
