Soil organic matter (SOM) plays a key role in the formation and stabilization of soil aggregates (Oades 1984); and continual addition of crop residue increases labile SOM near the soil surface, which increases soil aggregation and has a large impact on soil structure (Lu et al., 1998). No-tillage systems have higher SOM stock and also greater and m...
