soil texture profile

The system have 11 indicators, including the organic matter, phosphorus, potassium, zinc and effective, texture, pH, profile configuration, landform type, soil parent materials, guaranteed rate of irrigation and drainage capacity.

研究建立了荆州市耕地地力评价指标体系，选取了有机质、有效磷、速效钾、有效锌、质地、pH、剖面构型、地貌类型、成土母质、灌溉保证率和排涝能力11项指标。

The results showed that the maximum height of the capillary water rise of layered soil was mainly determined by the sand soil texture, position, thickness and their mutual relationship, and they also were closer connected with other soil texture in the profile.

结果表明：层状土壤毛管水的最大上升高度取决于夹层土壤的质地、厚度、层位及其相互关系，同时也与土壤剖面中其它土壤的质地密切相关。

Their common characters are scarce of organic matter, low content of nutrient, little CEC, weak eluviation, high content of calcium carbonate, profile developed a little and coarse soil texture.

有机质缺乏，养分含量低，阳离子代换量小，淋溶作用弱，碳酸钙含量高，剖面发育差，土壤质地粗是试区土壤的共同特征。
