Abstract
The yellow-grey earths of the Kurow-Duntroon area have a higher percentage of fine particles and organic carbon and are deeper than soils of the same group in the Ida Valley. the Arrow Basin, the Upper Clutha Valley, and the Maniototo Plains. Because of the high 15-bar retention value, the available moisture (2.55 in.) in the top 12 in. of the Kurow-Duntroon soils is not particularly high. Over the sOoil profile, however, the greater depth of soil means that the total available moisture is higher than that found in previous studies on soils of similar groups. Low macroporosities indicate that over-irrigation may lead to water-logging of some soils.
