Abstract

Investigation and analysis were conducted to study the variety cropland soil nutrients during 21 years(from 1981 to 2002) in Yucheng county. The result shows that the organic matter,total N and available K were increased 20%,30% and 16.4%,and the total P was decreased 42%.Most nutrients were increased on paddy field, and most nutrients were decreased on dry land. At the same time, the driving force of soil nutrients variation were find out. The measures that increase soil nutrients were put forward.
