文摘

The wind-erodible fraction of soil determining from rotary sieve (EF-r) are lower than that obtaining from flat sieve (EF-f). The relationships between EF-r and soil intrinsic properties depend on soil tillage/management. The EF-r is significantly associated with surface soil rock fragments content. The EF-r estimation equation in the RWEQ cannot be used to predict the measured EF-r.
