Study on Soil Quality Improvement in Weibei Taiyuan District

Abstract In order to fully understand the spatial change characteristics of soil quality after land remediation in Weibei Taihe District, this paper takes Long County, Weibei Taihe District as an example, selects some project areas after land remediation, conducts soil nutrient testing, and studies the organic matter and nitrogen, phosphorus, and potassium in the soil. The distribution characteristics of soil and the quality of soil were graded. The scientific evaluation of the quality of newly cultivated land in the area after land remediation showed that, except for the organic matter content in the land remediation area of Dingma Village, other indicators and other The regional indicators are in compliance with the standards. According to the traditional fertility improvement methods, the soil organic matter content is lower than the standard. The organic matter can be improved by applying organic fertilizer and promoting the return of straw to the field. It is suggested that through the combination of cultivated land and cultivated land, crop rotation and stubble should be implemented to ensure balanced supply of nutrients to the newly-added cultivated land so that the development of cultivated land can achieve sustainable, stable and high yield.
