Variation of Soil Nutrient Content under Different Land-uses of Xinyuan in Xinjiang
The indexes of soil nutrients,including alkali nitrogen,available phosphorus,available potassium,organic matter,pH and trace elements (Iron,Manganese,Copper,Zinc),were measured and soil quality under different land-use types were analyzed based on the evaluation index of soil quality.The results showed that the soil nutrient contents in farmland changed more significantly than any other land-use types.Variation coefficient of available phosphorus under different land-use types was the greatest while the variation coefficient of pH was the smallest.The content of zinc in woodland soil was higher than any other land-use types.Indexes of soil quality were as follows:grassland (0.647)＞ farmland (0.616)＞water-land(0.575)＞the forest(0.555)＞ the unused-land(0.319).The research of soil nutrients variation can provide the basic guidelines for practical land use management and adjustment,soil protection and sustainable development.
