was performed using 150 mesh and again wet sieving was performed using 200 mesh.
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.
The aggregate size groups were separated by dry sieving
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.
The GilSonic AutoSiever (Model GA-6) performs dry sieving
of fine powders to 5 microns with the utilization of 3" sieves.
Dry sieving of soil with a compact rotary sieve is the technique recommended for determining wind erodible fraction of agricultural soils for use in the wind erosion equation (6, 11).
SAS(1) Stepwise statistical analysis procedures were used to identify those physical and chemical properties from the Lincoln lab that were best correlated to the average erodible fraction from dry sieving.
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.
