The average level of the soil available potassium was 119.96 mg/kg, which decreased 18.94 mg/kg and 1.05 mg/kg one year averagely. But the decreasing trend alleviated in recent years. There were 39.5 kg/hm^2 nitrogen and 30.9 kg/hm^2 phosphorus (P2O5) more than needed averagely, and 150.0 kg/hm^2 potassium (K2O) in deficiency. Though the fertilizer application was high and the rate of fertilizer was 647.96 kg/hm^2 in nutrient, the ratio of organic to inorganic was still unreasonable. The ratio of the chemical fertilizer nitrogen phosphorus (P2O5) and potassium (K2O) was 1:0.42:0.14. The nitrogen application was enough and even higher than that was needed. The phosphorus was proper elementarily and potassium was in deficiency. The yield of wheat which was the main crop increased slightly and that of other autumn harvest crops was stable.

土壤速效钾7年平均值119.96 mg/kg,比第二次土壤普查时下降了18.94 mg/kg,平均每年以1.05 mg/kg的速度下降,但近年来下降趋势变缓;养分平衡中氮素平均盈余39.5 kg/hm^2,磷素(P2O5)盈余30.9 kg/hm^2,钾素(K2O)亏缺150.0 kg/hm2;全省施肥水平较高,每公顷总施肥量折纯养分647.96 kg,但有机无机比仍不合理,化肥氮、磷、钾投入比例1:0.42:0.17,氮肥充足,部分地区用量偏高,磷肥基本合理,钾肥不足;主要农作物小麦产量略有上升,其它主要秋收作物产量基本稳定。
