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 …

The Sandplain Lupin : Its Nutritional Value And Grazing Management, P W. Morcombe
Journal of the Department of Agriculture, Western Australia, Series 4
The sandplain lupin or Western Australian blue lupin (Lupinus cosentinii) was introduced to the West Midlands at the turn of the last century. Since that time it has been used as a self-regenerating summer forage for sheep and cattle.
Being deep rooted, it has adapted well to the sandy soils from Perth to Northampton, and plantings now cover more than 100,000 ha.
As few other improved pasture species will persist on these deep sands the sandplain lupin provides an important source of summer feed for grazing livestock. A stand can be grazed throughout summer at stocking rates of 10 to …

Grazing To Control Pasture Composition, R A. Bettenay
Grazing To Control Pasture Composition, R A. Bettenay
Journal of the Department of Agriculture, Western Australia, Series 4
APART from grazing management, there are a number of means by which the farmer can influence pasture composition.
With the exception of grazing, all of these processes involve recurring costs, so it is important to exert the utmost possible control through the grazing animal.
