What is Soil Aggregation and explain its beneficial role

Plant roots also promote soil aggregation with the help of their decay product. Gum or polysaccharides produced by certain microorganisms also cause soil aggregation.  Azotobacter, Baijerinckia and Rhizobium are examples of gum producing bacteria.
