| Abstract | Understanding of the characteristics of soil nutrients at the field and catchment scale is important for refining agricultural management practices and for improving sustainable land use. In order to analyze soil nutrient differences among different land use types and their relationships between land uses, 9 sampling sites including 3 land uses were selected in the Daqiaohe catchment on Yunnan of China. Significant differences in soil nutrients among these land uses were found. Higher values of soil nutrient in crop land soil, but lower values in forest soil and virgin soil. Nutrient contents decreased with soil profile depth increasing. All nutrient contents were poor in debris flow bottomland. At the same time, relationship between nutrient contents and grade contents was analyzed. The result showed that TP, AP and AK were significantly correlated with clay contents and slit contents at 0.01 level, while other nutrients were not correlated with clay and slit contents. There existed significant relationship between TP and sand contents, but for TN, the condition was found. However, nutrient was relation to many factors, thus relationship between nutrient contents and grade contents should he studied in future. |
