Quality of cultivated land can be termed as the summation of such factors as soil quality, environmental quality, management quality and economic quality of the cultivated land. Quality of cultivated land is generally low in China. The area of cultivated land with moderate and low quality accounts for above 2/3 of the total. However, there is no common understanding about how the quality of cultivated land will change among the scientists thought most believe that the quality is generally decreasing. Results from the farmland soil monitoring campaign show that soil fertility of cultivated land is gradually increasing in China as indicators of the fertility present. This confirms the argument that quality of cultivated land as a whole is getting better and better in China though some factors may still be a problem in some parts of China.
