  • Aggregate Size

    Aggregate size fractionation is based on the premises that: (1) organic matter binds mineral particles together. Aggregate size fractionation can then be used to separate the organic matter responsible for aggregation ( Puget et al., 1995 ) and (2) aggregates of different sizes correspond to different microbial habitats and provide contrasting conditions for decomposition ( Beare et al., 1994; Elliott, 1986 ).
