Study on the Physical and Chemical Properties of the Agriculture Soil of Enshi City
[Objective] The paper aimed to analyze the physical and chemical properties of the cultivated soil, judge the grade of the soil fertility of Enshi City and study on the relationship of the physical and chemical properties of the soil. [Method] The physical and chemical properties of the soil was analyzed, and the grade of the fertility of the soil was judged according to the grade 2 value of the dry land soil fertility, the correlation of the physical and chemical properties was investigated. [Result] Mean value of the organic matter, total nitrogen, available phosphorus and potassium in Enshi City were 29.96 g/kg, 0.80 g/kg, 7.18 mg/kg,126.45 mg/kg, 18.59 cmol/kg. Nitrogen, phosphorus and potassium and CEC had reached the 2 grades level of soil fertility in dry land, and available K and organic matter content had reached 1 level standard, belonged to high level. [Conclusion] The fertility of the cultivated soil in Enshi was high relatively, the correlation between the CEC and available K, organic matter, total N and pH value was prominent. The correlation between the pH value and the soil porosity percentage was also prominent.
