Improving Sustainable Production From Water Repellent Sands, Paul Blackwell Jan 1993

Improving Sustainable Production From Water Repellent Sands, Paul Blackwell

Journal of the Department of Agriculture, Western Australia, Series 4

The agricultural management of water repellent ( non-wetting) sands is difficult, and production from them is mostly low. However, there are ways to make them more productive.

Furrow sowing and the incorporation of dispersive clay are two likely methods to make these soils easier to manage, more productive and more profitable than they are now.

This article discusses several aspects of our research on water repellent sands. In addition, some of the costs and benefits of alternative management strategies are outlined.

North Stirling Land Conservation District - Soils Manual, Justin Hardy, Peter J. Tille

Soil conservation survey collection

The North Stirling Land Conservation District is located between Katanning and Albany on the northern edge of the Stirling Ranges in south-western Western Australia.It includes parts of the Shires of Cranbrook and Tambellup, covering approximately 100,000ha of the catchment of the North Stirling basin. The basin is a flat area formed on Eocene sediments with poorly defined drainage lines and many salt lakes. It is surrounded by low granite and sandstone hills. The climate is Mediterranean, with cool wet winters and hot dry summers. Average annual rainfall ranges from 375-500 mm per annum. There is very little surface or underground …
