A new approach for calculating aggregate stability: Mean weight
Aggregate stability (AS) of each aggregate size obtained from dry sieving was separately exposed to wet sieving using the Yoder type wet sieving apparatus (Nimmo and Perkins, 2002). Wet sieving analysis was replicated four times for each sampling point (3 sampling point × 4 replication = 12 replications for each aggregate size).
