Simulated rainfall experiments were conducted to compare the amount of nutrient loss in the cinnamon soil,brown soil and red soil.The results showed that the runoff and sediment yield of the cinnamon soil were the least and the red soil was the biggest in the three types of soil under the conditions of rainfall simulation.The loss amount of total nitrogen and available phosphorus and potassium in soil carried by runoff accounted for the loss of total amount 77.27%~99.79%.Runoff was the main driving force of...
