Effect of Stability of Soil Water-Stable Aggregates under Different Land Use

Abstract:

Using the Northeast region for the study area as it has a typical different land use types, through the soil sampling and analysis, research and compare different land use distribution of soil aggregates. The results showed that among different land use patterns, the surface (0 ~ 20 cm) has the maximum of water stable aggregates <0.25mm (up to 52.262%). Whether it is farmland or plantations, subsurface soil aggregates are higher than the surface aggregates content, but showing natural secondary forest soil structure has the stability characteristics that natural secondary forest water-stable aggregate content has no significant effect; soil aggregates average body weight diameter and geometric mean diameter, the surface fields are the lowest, the use of forest land into farmland, the mean weight diameter and geometric mean diameter, has declined. In general, the surface 0 ~ 20 cm is higher than the subsurface 20 ~ 40 cm.
