Due to the impact of crop planting structure and habits on the nutrient content of soil, the number and population structure of microorganisms will also be damaged, resulting in certain damage to the quality of cultivated land. By taking effective measures to improve the soil condition and promote the sustainable development of local agriculture, it can provide more powerful support and guarantee for the local socio‐economic development. Starting from the purpose and task of soil general exploration, this paper analyzes the layout methods of sample points for soil general exploration, and puts forward suggestions for soil remediation, with a view to providing necessary reference for the construction of high standard farmland projects.
