Wheat Yield Potential And Land Management Constraints In The South West Of Western Australia, Dennis Van Gool
Wheat Yield Potential And Land Management Constraints In The South West Of Western Australia, Dennis Van Gool
Resource management technical reports
This report provides the underpinning information to help improve the long term profitability of wheat cropping. It documents the realistic potential yield of the 18 million hectares of agricultural land in the South West of Western Australia and the gap between this potential and the actual yields, based on shire averages. This report also summarises major land management constraints that limit the yield potential. This information can be used to aid strategic planning at different levels, for example state, shire and, with care, as a starting point for farm planning.

Toward Better Minimum Tillage For South-Coastal Sandplain Soils, W L. Crabtree
Resource management technical reports
Seventeen farmers compared their conventional cropping practices with some form of minimum tillage cropping. The minimum tilled crops yielded 21 percent less grain than the conventionally sown crops. The reasons for these decreased yields were in most cases related to inexperienced management. The minimum tilled treatments usually had very poor weed kill strategies which often resulted in large weeds at sowing, very cloddy seed-beds, and numerous insects in the young crops.

Resource management technical reports
The most serious erosion was found to be occurring in the Donnybrook area due to a combination of erosive winter rainfall, steep slopes and erodible soils. The most serious erosion was found to occur when storm runoff entered the vegetable plots from above, providing a transporting medium for the cultivated soil. A predictive model of erosion showed that soil texture, furrow slope, plot length, rainfall erosivity and canopy cover were significant factors affecting soil loss.

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 …

Water Erosion On Potato Land During The 1983 Growing Season Donnybrook, D J. Mcfarlane
Water Erosion On Potato Land During The 1983 Growing Season Donnybrook, D J. Mcfarlane
Resource management technical reports
Soil losses over a three month period varied from 10 to 49 mm.. Soil loss was most highly correlated with length of slope of the plots. Other important factors appeared to be slope angle and soil textures. Grade furrows appear to be the best method of breaking-up long slope lengths. The low capacity of the furrows requires them to be on grades of about 4 to 4 per cent to prevent siltation and overtopping during high density storms.
