In this study, soils with 2-year continuous no-tillage treatment were sampled from 5 experimental sites representing 5 agricultural districts in Jiangsu Province. The shrinking property and crushing strength of these soils were measured. Soil structure and drainage state could be improved by no-tillage. There existed close relationship between soil volume change rate and the content of clay with diameters of both 0.01mm and 0.001mm. The difference of soil crushing strength between conventional tillage and notillage was also related to clay content. Therefore, in these agricultural districts or soils with a high clay content, it was more important to pay attention to soil filth and to choose a suitable tillage method.
