treated by dispersion agents before the dry sieving. Another approach, which is able to liberate more microaggregates that are trapped within macroaggregates (Six et al., 2000), can be to mechanically crush the macro-aggregates down to microaggregate sizes, using a uniaxial crushing procedure. Uniaxial crushing enables the break-
