The effects of lupin, field pea, barley, canola, linseed and lentil crops on the surface (0-0.10 m) aggregation of a red earth were investigated in the field. Soil friability after cropping was in the decreasing order: lupin, lentil, canola, field pea, linseed (equal to barley). Both lupin and canola cropping produced significantly stronger aggregates than barley, lentil and field pea. There was a significant correlation between the tensile strength of the aggregates and amount of dispersed clay released from moist soil.
