Research on Soil Pollution Channels and Remediation Methods in Farmland

Soil pollution on arable land is a major factor that leads to a decline in the quality of arable land, a decrease in land use efficiency, and a threat to national food security in China. Starting from the current situation of soil pollution in China, this article analyzes the main sources of soil pollution on arable land, and focuses on the main causes of soil pollution in the industrial and agricultural fields. Based on this, soil remediation measures are proposed through physical, chemical, biological, and joint repair technologies, in order to provide some ideas for the protection of arable land and the effective improvement of arable land quality in China.
