Soil morphological properties in relation to depth to the groundwater table in a sandy landscape near Perth

Abstract

In an area of about 500 ha, in a sandy landscape, 154 soil profiles were classified according to colour, consistence, and thickness of horizons, and the resulting six classes were shown to be associated with depth to groundwater table. Where depths were > 11 m profiles had an A2 horizon which was not bleached. Where depths were < 7 m profiles included a bleached A, horizon and possibly an organic B horizon. Also profiles having a B horizon hue of 7.5YR were associated with greater depths to water than those with hues of 10YR and 2.5Y.
