Abstract

The AA. presumed that the aggregate stability and the distribution of organic carbon and nitrogen in different aggregate fractions were different and would be affected by different plant communities in comparison to cropland and bare fallow land. Therefore, the aims of this study were to elucidate the effects of different plant communities on soil aggregate stability and the distribution of organic carbon and nitrogen in different aggregate fractions by using ultrasonic method, both in old forest areas and in new afforestation areas, in order to prove that the different plant covers enhance soil aggregate stability. Soil samples were collected from the hilly-gully area on the Loess Plateau : results and discussion
