Soil quality is an important factor affecting grain yield and quality per unit area. Due to soil loss, soil desertification, acid rain and heavy metals, pesticide pollution and other reasons, China's current soil quality problems are mainly reflected in the overall low quality of soil degradation is more serious. In 2004, 37.3% of China's cultivated land was low-yielding and 41.2% of middle-yielding land, accounting for 78.5% of the total.
