Effects of afforestation methods on nutrient runoff and fertility quality of red soil.
造林方式对红壤养分流失和肥力质量的影响

Based on the measured data of soil nutrients and soil erosion, three afforestation methods, including controlled burning, full cultivation and bunch plantation, were compared .The results showed that both controlled burning and full cultivation enhanced erosion of soil and nutrients , caused decrease of organic matter, nitrogen , phosphate and potassium and led to degradation of soil fertility quality.
