ABSTRACT:
A simple rapid rotary sieve has been developed to determine the percentage of soil aggregates (greater than 0.84 mm) that are not erodible by wind and the relative mechanical stability of dry soil aggregates. Aggregate stability, which is influenced by agricultural management systems, is important in controlling erosion. The rapid rotary sieve is simple to construct, requires less than $200 for materials, and takes one-sixth the sieving time of a standard compact rotary sieve.
