Wet sieving versus dry crushing: Soil microaggregates …
It seems plausible that both wet sieving and dry crushing yield different results for the OC distribution of the different aggregate size fractions. During wet sieving (especially with sonication), large primary particles are dispersed from fine particles (containing the most OC) (Nahidan & Nourbakhsh, 2018). This leads to an underestimation of ...
