Specifications are given for a more compact, lightweight rotary sieve that can be transported and handled more conveniently than the two‐sectional units previously developed to determine the size distribution and mechanical stability of dry soil aggregates. The state and mechanical stability of the dry aggregates is a closer index of field structure than the state of the primary aggregates determined by wet sieving. In addition to the primary and the dry aggregates, the surface crust and the highly water‐dispersible materials among the dry aggregates also markedly reflect the physical structure of soil as it exists in the field.
