| Abstract: | Abstract. Hard-setting soils are widespread in dry regions. Their properties are described and a physical explanation for hard-setting behaviour is given. The limitations on soil management and physical fertility caused by hard-setting depend on timing of rainfall or irrigation with respect to cultivations and crop development, and much research is needed to quantify reductions in crop yield imposed by these limitations. |
