2001; Fierer and Schimel 2003), and dry sieving
is preferable to wet sieving for preservation of structure and soluble SOC components (Sarkhot et al.
The aggregate size distribution and aggregate stability in both dry sieving
and wet sieving will be measured.
125 mm in diameter) when separation of aggregates by dry sieving scrapes off hydrophobic coatings and accumulates these coatings in the finest materials (de Jonge et al.
Soil aggregates of 10 mm size (5 15 mm) were selected from the 2-25-mm fraction, which had been separated by dry sieving soil samples from the topsoil (0-0.
Significant differences between land use at each site, for the dry sieving, was determined by use of a t-test (P = 0.
Generally, a clear trend can be difficult to establish with dry sieving comparisons as the results can be influenced by intensity of tillage (Prove et al.
A dry sieving technique was used for measurement of the soils' aggregate size distribution.
The Red Clay reference soil appeared to be more friable and easier to break down than the corresponding cropped soils, which resulted in a 36% increase in the percentage of aggregates [is less than] 125 [micro]m (meaned over all rotations) following dry sieving (Table 2).
