Abstract:
Soil nutrients provide the nutrients necessary for crop growth, which mainly come from soil minerals and soil organic matter. This paper summarized and analyzed the soil nutrient survey data at various monitoring points from 2017 to 2022 in Yaodu District. The results showed that organic matter, total nitrogen content, slow-acting potassium and soil pH were basically stable in Yaodu District, available phosphorus and available potassium increased year by year, and organic matter content showed a decrease in highcontent areas and an increase in low-content areas. The research results accurately grasp the characteristics of soil nutrient changes in Yaodu District, which is of great significance for soil nutrient management, scientific fertilization, and sustainable agricultural development in Yaodu District.
