2006年通过对阿荣旗29万 hm~2耕地土壤取土化验分析,结果表明:土壤有机质含量平均为47.20g/kg,全氮含量平均为2.36g/kg,有效磷含量平均为23.18mg/kg,速效钾含量平均为163.8mg/kg。与1982、2002年土壤化验结果相比,有机质、全氮、速效钾含量下降明显,有效磷大幅度上升。
The result of soil organic matter analysis of 290,000 hm ~ 2 cultivated soil in Arong Banner in 2006 showed that the average content of soil organic matter was 47.20g / kg, the average total nitrogen content was 2.36g / kg, the average effective phosphorus content was 23.18mg / kg, The average available potassium content was 163.8 mg / kg. Compared with the result of soil test in 1982 and 2002, the contents of organic matter, total nitrogen and available potassium decreased obviously, and available phosphorus increased significantly.
