Based on the second soil census of whole farm in 1980 and soil testing results using GPS in 2000 and 2010, the paper studied the time dimension variation characteristics of soil organic matter, total nitrogen, alkali-hydrolyzable nitrogen, available phosphorous, available potassium and pH value in the plough layer and profile of Fuxingwei farm, aiming to explore the time dimension variation rules of soil nutrients on the farm scale and provide theory basis for the formulation of precise fertilization strategy on rice and wheat.
