| Abstract: | The paper analyzed the soil pollution in the farmland affected hy chemical fertilizer,which included increasing the quantity of heavy metal and poisonous elements, causing the accumulation of the nitrates in the soil, destroying the soil structure, promoting the soil acid, reducing the soil microorganisms and the movement of them. Based on the current analysis, the paper put forward the countermeasures, which included strengthening the consciousness of environmental protection and the monitoring and management of the soil fertilizer, using organic fertilizer, popularizing the technology of applying fertiliz- er, using the nitrify inhibitor, improving the way of using chemical fertilizer, |
