Measurement and analysis of farmland soil cation exchange capacity in Xiangyang
Zhao Xiang;Xiang yang environmental monitoring central station;
Soil cation exchange capacity( CEC) can reflect the level of soil fertility,fertilizer retention capacity and buffering capacity.Throughinvestigation,sampling and laboratory analysis of soil cation exchange capacity of 16 spot in Xiangyang city,we discovered that the CEC of Xiangyang soil are concentrated in the 15- 20 cmol / kg,which belongs to the medium fertility soil. At the same time,through the determination of soil physiochemical indexes,such as the content of soil organic matter,PH value,we discovery that they are very good correlation to soil cation exchange capacity.
