Drainage And The Law, G A. Robertson
Drainage And The Law, G A. Robertson
Journal of the Department of Agriculture, Western Australia, Series 4
Drainage is being increasingly used in Western Australia as an attempted cure for land salinisation and waterlogging. This is nor surprising as drainage is a technical approach that has, in some cases, improved saline land and reduced the effects of waterlogging. However, drainage is not always successful or cost-effective. A detailed site assessment is required before any large or costly drainage system is attempted. Articles in this issue of the Journal of Agriculture discuss that aspect in detail.

This report examines the residual value of lupins and several other species grown at ECRS in 1984 on the yield of wheat in 1985 (85 C 25). 85 C 46 examined the residual effect of several lupin species and varieties grown under different nutritional treatments in 1984 at two sites differing in rainfall on wheat yields in 1985. 85 C 47 examines the interaction between levels of applied potassium and deep cultivation (ripping) on the yield of wheat at a low K, dry site.
Report on 85 C 27, 85 C 46 and 85 C 47.

Many farms in Western Australia were cleared and developed before there was a full and clear understanding of the effects of bush clearing - that is salinization of soil and water supplies, wind and water erosion, waterlogging and soil structure decline. The productive capacity and inherent problems of the different soil types was also largely unknown.
Modern-day Conservation Farm Planning aims to provide a blue-print for the redevelopment of properties to ensure long term soil fertility, to prevent soil erosion and degradation by waterlogging and salinity. It also provides for a spread of reliable stock watering points and more efficient …
