Review of analytical methods for aggregate size distribution and water-stability of soil macro-aggregates
土壤水稳性大团聚体测定方法综述

Wet-sieving method is a classical and still the most prevalent procedure for testing the water stability of soil aggregates.Three main mechanisms are attributed to the breakdown of soil aggregates during wetting including slaking(breakdown caused by the compression of entrapped air in the soil pores),differential swelling and physic-chemical dispersion.The existing wetting methods can be divided into fast wetting and slow wetting according to the velocity of wetting,and atmospheric pressure wetting and high...
