Abstract:
The research was conducted in Gaocheng，Wuji，Zhengding，analyzed the status of soil nutrient with wheat /maize rotation in the piedmont plain of Taihang mountains and the balance of nitrogen，phosphorus and potassium of the cropland． The results indicated that compared with the second national soil survey in the three counties (city), the average of soil organic matter content had been improved from 1． 13% to 1． 86%，was still at a low level; the average of Total nitrogen content had been improved from 0． 73 g /kg to 1． 14 g /kg，was at a middle level; the average of Available phosphorus content had been improved from 10． 3 mg /kg to 29． 83 mg /kg，was at a high level; the average of Available potassium content had been improved from 103． 0 mg /kg to 117． 2 mg /kg，was at a middle level． In general， the nutrient of nitrogen，phosphorus and potassium of the farmland in three counties(city) was surplus as a whole． In the current condition of agriculture production， the overdue fertilization is the main cause of that．
