First, chemical fertilizer, pesticide pollution during the growing process of crops will use a large number of chemical fertilizers and pesticides, which will not only produce certain pollution of agricultural products, but also cause very serious pollution of the soil. Although the use of large amounts of chemical fertilizers and pesticides during crop growth can increase crop yields, excessive or long-term use can affect not only the soil's own fertility It also makes crops less safe to eat. Radioactive Element pollution with the rapid development of nuclear technology, nuclear technology has been widely used in scientific research, industry and agriculture and other fields, which will increase the amount of radioactive elements in the soil. The radioactive elements in the soil come mainly from the atmosphere, which contains the gases produced after the Earth's nuclear experiments. The gases contain the debris which will enter the soil through natural rainfall or wind blowing And is absorbed by the soil, so that the amount of radioactive elements in the soil increases, so the longer the amount of radioactive elements in the soil remains, have some impact on both the biological and the food chain. The solid pollution of soil by solid waste mainly comes from the solid waste of industry and the rubbish produced by human life. In the course of daily life people will not be disposed of garbage on the soil, after long-term wind and sun, will increase the activity of heavy metals in the soil. At the same time, in order to effectively improve the yield of crops will be used to cover the film, if the use is not completed in time for recycling treatment, will also cause a certain degree of soil pollution. Guoqing environmental protection focuses on the design and manufacture of soil remediation and solid waste treatment technology and equipment, which can reduce the cost of soil remediation.
