Merging Conservation With Production In Remnant Bush, Anne Morgan, Alison Fuss
Merging Conservation With Production In Remnant Bush, Anne Morgan, Alison Fuss
Journal of the Department of Agriculture, Western Australia, Series 4
Exports of cutflowers and foliage from Western Australia are now worth about $17 million a year. A third of this is picked from the bush, either on Crown Land or areas of remnant bush on private property. While the industry's future lies in cultivation, bush picking is likely to remain important for some years. This can provide both extra income for farmers and benefit the environment - as long as care is taken
Lupin Stubbles : Getting The Best With Weaner Sheep, Keith Croker, Colin Mcdonald, Jeremy Allen
Lupin Stubbles : Getting The Best With Weaner Sheep, Keith Croker, Colin Mcdonald, Jeremy Allen
Journal of the Department of Agriculture, Western Australia, Series 4
Sweet lupins are now grown on about a million hectares in Western Australia each year. If half of the State's seven million weaners were grazed as recommended on half of the lupin stubbles, it could generate about $15 million from reduced supplementary feeding, greater wool production and other advantages. But correct management is important, particularly knowing when to take weaners out. Research by the Department over the last five years is now indicating how this should be done.
Using Saltland In Pakistan : An Australian Connection, Ed Barrett-Lennard, Riaz Qureshi
Using Saltland In Pakistan : An Australian Connection, Ed Barrett-Lennard, Riaz Qureshi
Journal of the Department of Agriculture, Western Australia, Series 4
Pakistan and Australia have a common enemy in salt. In each country millions of hectares of previously productive land have been affected by salt (or have the potential to become saline) because of inappropriate agricultural development. Since 1989 the Western Australian Department of Agriculture has participated in a research project in Pakistan which involves revegetation of salt land using Australian shrubs. Early results are very promising.
Careful Clip Preparation Will Increase Profit, Peter Metcalfe, Ric Collins
Careful Clip Preparation Will Increase Profit, Peter Metcalfe, Ric Collins
Journal of the Department of Agriculture, Western Australia, Series 4
The current wool market has forced wool growers into producing the maximum number of kilograms of quality wool for the least cost. Preparation of the clip is now much more important to maximise possible net returns. Careful clip preparation will ensure that growers receive the maximum overall average price for each kilogram of wool in the clip.
How Sustainable Is Grazing Sheep On Annual Pastures In The Woolbelt?, Don Mcfarlane, Richard George
How Sustainable Is Grazing Sheep On Annual Pastures In The Woolbelt?, Don Mcfarlane, Richard George
Journal of the Department of Agriculture, Western Australia, Series 4
Low wool prices have reduced the profitability of producing wool from clover-based annual pastures in the south-western woo/belt. The heavy reliance on one commodity is economically unsustainable for many farmers. But we should also consider how ecologically sustainable the practice is.
Shallow-rooted annual pastures contribute to widespread salinity in the area, annual legumes are acidifying the soils and making them water repellent, and bare, detached soils from heavy grazing cause sheet and rill erosion during autumn storms. In addition, stock are degrading remnant vegetation and destroying the soil's structure.
To counteract this degradation, the woo/belt needs more perennial pastures and …
No-Tillage Sowing Decreases Water Erosion On Loamy Soils And Increases Earthworm Activity, Kevin Bligh
No-Tillage Sowing Decreases Water Erosion On Loamy Soils And Increases Earthworm Activity, Kevin Bligh
Journal of the Department of Agriculture, Western Australia, Series 4
No-tillage sowing places seed and fertiliser in the soil without loosening all of the topsoil. Soil is cultivated only in the sown rows, leaving the inter-row areas largely undisturbed.
No-tillage sowing reduces both wind and water erosion. Soil structure is generally improved, and pasture regeneration is increased because seed is not buried too deeply for re-establishment.
Two long-term trials were establis_hed on loamy soils to determine effects of tillage and cropping on runoff and soil loss.
Bluegum Timberbelts For Profitable Landcare, Peter Eckersley
Bluegum Timberbelts For Profitable Landcare, Peter Eckersley
Journal of the Department of Agriculture, Western Australia, Series 4
Revegetation with tasmanian bluegums in wide-spaced timberbelts appears to offer high returns, especially in areas where high winds cause crop and stock losses and where land can be saved from salinity and wwaterlogging.
In the South Coast and South-WestRegions, timberbelts will complement existing enterprises and so optimise overall land use. Graziers should be able to maintaine their stock numbers while creating an on-farm superannuation package.
The Department of Conservation and Land Management has been a major player in the development of bluegum timberbelts, but a few farmers are now adapting this concept to better suit their needs. Initial results are …
Getting The Best From The Woolbelt, Department Of Agriculture And Food, Western Australia
Getting The Best From The Woolbelt, Department Of Agriculture And Food, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
Articles in this issue of the Journal of Agriculture discuss prospects for the wool industry and strategies for wool growers to increase their income and their long term viability.
The impact of low wool prices is greatest in the 'woo/belt' (see map) and the southern pastoral region. There is a need to boost the profitability of wool production and to increase income from sources other than wool in these regions.
The Productivity and Diversification Initiative for Wool Growers is refocussing Department of Agriculture resources to assist wool growers reduce costs, increase productivity and diversify into alternative enterprises.
The strategies recommended …
Quality Wool Production At Lower Cost, Peter Metcalfe
Quality Wool Production At Lower Cost, Peter Metcalfe
Journal of the Department of Agriculture, Western Australia, Series 4
Low wool prices are forcing farmers to reduce their sheep management costs but, fortunately, cost cutting is not resulting in lower wool production, poorer wool quality or lessened sheep care on the best wool growing properties.
Red Mud : Cutting Pollution And Boosting Yields, Rob Summers
Red Mud : Cutting Pollution And Boosting Yields, Rob Summers
Journal of the Department of Agriculture, Western Australia, Series 4
A by-product from the refining of bauxite ore in the South-West is proving a bonus for agriculture.
When spread over the land, not only is it improving soil quality, but it is helping to prevent leaching of phosphorus and the consequent massive algal blooms in the waterways.
Bauxite residue is also showing considerable promise in human and animal effluent disposal systems, composting urban refuse, sewage treatments and as a road base.
Western Australia is now in the forefront of this research which is attracting world-wide interest.
