Evaluation of methods for determining soil aggregate stability
Aggregate stability is commonly determined by wet sieving based on early work of Kemper and Koch (1966) and Kemper and Rosenau (1986). Aggregate breakdown during wet sieving is largely due to slaking and to a lesser extent to the physical effects of water movement during lifting of the sieve and abrasion on the sieve surface (Emerson, …
