Managing For Stubble Retention, Linda Leonard
Managing For Stubble Retention, Linda Leonard
Bulletins 4000 -
One of the objectives of sustainable farming systems is to retain as much cover on the soil as possible – this helps to maintain soil structure and protects the soil from erosion.
Improving productivity, maintaining soil structure, and stabilising fragile soils are some of the desired aims of farming. Sound rotations, reduced tillage, effective use of herbicides, maintenance of ground cover and careful management of stock are part of the management process used in achieving these goals.
This Bulletin provides an introduction to stubble retention systems. Its purpose is to create an awareness of the benefits and principles of stubble …

With the discovery of the role of trace elements, large tracts of land in the south west of Western Australia, previously regarded as unsuitable for agriculture, were cleared in the 1950s and 1960s. Much of this land was taken up as Conditional Purchase Blocks, a scheme which enabled conversion of unalienated crown land to freehold title providing a set proportion of the block was 'developed'.
However, the removal of the natural deep rooted vegetation and its replacement with pasture species (up to 90% of privately owned land in the Napier-King LCD area is cleared) has not been without problems. The …
Conservation For Production : Kings Rocks Catchment Report, William Oldfield
Conservation For Production : Kings Rocks Catchment Report, William Oldfield
Agriculture reports
The aim of this report is to bring together current information on the land and ideas which will provide landholders of the King Rocks catchment group with a basis to make more informed decisions about managing the land. The report contains information on how the landscape was formed, how areas become degraded, what are the present recommended ways of fixing land degradation and what are the most productive means of farming the land.
Managing Bushland On The Farm, Penny Hussey
Managing Bushland On The Farm, Penny Hussey
Journal of the Department of Agriculture, Western Australia, Series 4
Since the time of European settlement in Western Australia, the replacement of native vegetation with crops and pastures has led to problems for both agricultural production and nature conservation. The most obvious of these are hydrological changes leading to salinisation and waterlogging, and the extinction of some native plants and animals.
Protection of remaining remnants of native bushland, together with revegetation, is increasingly seen as important ways of achieving sustainable agriculture and maintaining our unique wildlife.
Improving Sustainable Production From Water Repellent Sands, Paul Blackwell
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.

Controlling Wind Erosion In Field Pea Stubbles, Jeff Russell
Controlling Wind Erosion In Field Pea Stubbles, Jeff Russell
Journal of the Department of Agriculture, Western Australia, Series 4
The area sown to field peas in Western Australia's eastern wheatbelt has increased from 4000 ha in 1985 to about 35, 000 ha in 1992.
While field peas can be grown on soil types not suited to lupins, their stubble is highly fragile and prone to wind erosion, even at low grazing pressure. This is one reason why some farmers are hesitant to grow field peas.
Haroest losses of field peas can also be high; levels of JOO to 200 kg/ha of seed on the ground are not uncommon. For this reason farmers believe the stubbles should be grazed.

Soils Of The Northam Advisory District. Volume 3. The Darling Range And West Kokeby Zones, Ian Fulton, Neil Clifton Lantzke
Soils Of The Northam Advisory District. Volume 3. The Darling Range And West Kokeby Zones, Ian Fulton, Neil Clifton Lantzke
Bulletins 4000 -
This manual describes the soils of the Department of Agriculture's Northam advisory district. Information is provided on the characteristics of each soil, its capability is discussed and yield estimates for the major land uses are given.
Designed for use by farmers and Department of Agriculture staff, the manual’s primary aims are to:
- Assist with the identification of the advisory district’s soils types
- Match land use with soil quality
- Improve farm productivity and efficiency
- Reduce the incidence of land degradation
