Resource management technical reports
The problems of wind erosion in part of the south coast of Western Australian sandplain area were described previously (Gorddard et al, 1981) with 7.3 per cent of cleared and 18.3 per cent of the cropped area showing evidence of sand blasting. Department of Agriculture trials have shown that the loss of the top four millimetres of top soil from pastured paddocks can reduce following crop yields by up to 20 per cent (Marsh and Carter, 1983). Animal production problems associated with wind erosion of soils have not been quantified, but a number of problems such as reduced carrying capacity …

Technical Bulletins
The water-holding capacity of these soils, and their location in a low rainfall area combine to make them marginal for producing grain. In contrast to sowing wheat on ley pasture, mechanically fallowing the year before planting markedly improved grain yields by 1.3 to 4 times.
