Hai’an County currently has an area of 840,000 mu of cultivated land, of which 150,000 mu are high-yield and stable-yield farmland (hereinafter referred to as “Gao-stable”). Building a stable and high-yielding farmland is a basic task to ensure the sustainable development of agriculture. In order to understand the status of soil fertility, fertilization level and yield structure of the high-yield farmland, the technical index system of soil fertilizers in the high-yield farmland was established. From 1998 to 2000,
