| Abstract: | Soil aggregate is the basic unit of soil structure, and its formation and stabilization has direct effect on soil fertility and crop growth.For black soil with high content of organic matter,organic cementing substance is an important factor in forming soil aggregates.Based on the recent researches on organic cementing agents,this paper was focused on the nature of organic cementing substances,the effect of soil organisms and plant roots in forming soil aggregates,and the theoretical models and stable mechanisms of soil aggregate formation. |
