Tree Crops For Profit And Land Improvement, John Bartle
Tree Crops For Profit And Land Improvement, John Bartle
Journal of the Department of Agriculture, Western Australia, Series 4
Western Australian agriculture is deficient in good perennial species. The traditional segregation of agriculture and forestry has diverted attention from commercial wood producing trees as a potential perennial crop. Recently, scientists have made rapid progress in developing tree cropping systems suitable for extensive use in the wetter (more than 600 mm average annual rainfall) areas of the lower south-west. There is potential for a major industry based on fast-growing eucalypts for pulpwood. The foundations for this industry developed from work on agroforestry, forestry sharefarming and salinity control.

The Extent And Cost Of Waterlogging, Don Mcfarlane, Buddy Wheaton
Journal of the Department of Agriculture, Western Australia, Series 4
Waterlogging is an underrated and not widely recognized problem in our cropping areas. Before we can tackle the problem through drainage and alternative cropping systems, we need to know its extent and how much crop yield is lost. The effect of waterlogging on pasture growth is also poorly known.

Contour Cultivation : Cheap Erosion Control, T R. Negus, B. Barrett
Journal of the Department of Agriculture, Western Australia, Series 4
Although the benefits of contour cultivation are well recognised, it makes cultivation more difficult, particularly if the paddock is split by contour banks and grassed waterways. However, a comparison east of Pingelly indicates that contour cultivation is little more expensive or time-consuming than ordinary cultivation.
