通过对川市郊区大龙山，十里铺，八中附近的水稻田耕层土壤进行取样，对pH值，有机质和速效磷，速效钾及碱解氮进行测定分析。结果表明其pH值平均值为4.81，属酸性土壤；有机质平均值为20.29 g/kg，土壤有机质含量处于中等水平；速效磷平均值为19.31mg/kg其含量相对比较合理；速效钾平均值为58.92 mg/kg，速效钾的含量较缺乏；碱解氮平均值126.96 mg/kg，处于较高的水平.
Through the big-city suburbs in Yongsan, Shi Lipu, eight in the nearby rice Geng Tian layer of soil sampling, the pH, organic matter and phosphorus, potassium and nitrogen base analysis determined. The results showed that the average pH of 4.81, an acid soil organic matter average of 20.29 g / kg, soil organic matter content in the middle level of available phosphorus average of 19.31 mg / kg its content is relatively reasonable for the average K 58.92 mg / kg, the content of a lack of available K; base N average 126.96 mg / kg, has a higher level.
