These factors include nutrient cycling, soil organic matter, rainfall infiltration, addressing soil … WebSoil aggregation is an essential mechanism for the stabilization of SOM, especially in organic soils (Lutzow et al., 2006). It affects soil physical (aeration), chemical (water infiltration), and biological (microbial) activities. If SOM is within soil aggregates, aggregate formation physically protects SOM from biological degradation.
