Corrigenda - Modifications to self mulching (I_sm) behavior and their implications

Abstract

The relationship between a laboratory-based numerical index of self-mulching, I-sm, and the actual ability af soils to re-aggregate from the puddled state mas assessed and confirmed. Self-mulching behaviour, as reflected in this laboratory index, was modified, both by changing the calcium status of soils, and by the mixing together of soils having a wide range of self-mulching tendencies. The results reveal the potential significance of mineralogy and of fabric in the manifestation of self-mulching behaviour and the potential for inducing this sort of behaviour in poorly structured soils.
