Dunhua City, under the jurisdiction of the Yanbian Korean Autonomous Prefecture in Jilin Province, is the largest agricultural city in Yanbian Prefecture. It belongs to the temperate zone in the humid monsoon climate with large temperature difference between day and night, which is conducive to crop growth. The agricultural products produced are of good quality and pollution-free. Province important corn, soybean production base. Over the years, due to climate change and primitive tillage methods, resulting in a larger loss of runoff, effective plowing year after year, plow gradually thickening, forming a ground thin not to pay the situation. According to the survey, Dunhua City, Shahe along the town of soil organic matter content, less than the total crop growth requirements of more than 50%
