Guidelines For Management Of Farmland Adjacent To The Busselton Wetlands, William Oldfield, Department Of Conservation And Land Management, Department Of Planning And Infrastructure

Bulletins 4000 -

The Busselton Wetlands are a chain of wetlands that lie parallel with the coastline of Geographe Bay, Western Australia and in close proximity to the town of Busselton. The main issues for the maintenance of quality of the wetlands are nutrient levels and habitat value. This guide outlines many of the current best practices related to farming around wetlands.

Images 2.1 : An Integrated Model Of An Arid Grazing System, Z G. Yan, K M. Wang

Resource management technical reports

The name IMAGES stands for An Integrated Model of an Arid Grazing Ecological System. The model was initiated by Dr R. Hacker in 1987-8 as an activity to (1) evaluate alternative management strategies and (2) identify key ecological processes and research priorities in shrub rangelands of Western Australia. Version 1 of the model was published in Agriculture Systems in 1991 (Hacker et al. 1991) and here after will be referred to as IMAGES 1. IMAGES 1 is a vegetation model, capable of predicting the prob ility of recruitment and mortality of the desirable species in a given vegetation type under …

Land Capability Assessment For The Wellington-Blackwood Survey, Peter J. Tille

Resource management technical reports

This report has been produced to provide more detail on the land capability assessments presented in the Wellington-Blackwood Land Resources Survey (Tille 1996). In that report, the land capability of each of the soil-landscape subsystems has been summarised with a brief description. Capability ratings are provided here for each of the map units (including subsystem phases) which appear on the two map sheets (Tille et al. 1996) accompanying the Wellington-Blackwood Land Resources Survey.

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 …

Trees And Livestock : A Productive Co-Existence, Richard Moore

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

Trees, as part of farming can help to combat land degradation problems and produce a good economic return from timber at the same time. For example, there is now clear evidence that planting trees can help combat salinity by lowering water-table levels. Trees can also substantially improve overall farm productivity by providing shelter for pastures and livestock. The challenge is to find practical and economical methods of integrating trees and farming. A combination of widely-spaced trees and livestock is one promising method. This article describes the benefits of this type of agroforestry to farmers, suitable locations and how to practice …

Erosion Potential Of Phomopsis-Resistant Lupins, D J. Carter, Paul Findlater

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

During lupin harvesting, up to 20 per cent of the grain remains on the ground. This non-harvested or pilt grain is a valuable feed for sheep during early summer because the pods, leaf and stem generally provide little nutrient in the stubnbles. In addition, the more efficient the weed control, the less valuable are the stubbles.

The disease lupinosis caused by Phomopsis leptostromiformis restricts the amount of grazing from the lupin stubbles, and hence the risk of wind-erosion of stubble paddocks.

However, the introduction of lupin varieties moderately resistant to Phomopsis and with reduced potential to cause lupinosis means that …

Producing 20-Month Old Beef Steers Off Annual Pasture, K D. Greathead, D. J. Barker, W. J. Ryan

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

A recent Mt Barker experiment compared two systems of fodder conservation with continuous grazing, using two types of steers, at three stocking rates. Year-round performance, carcass composition, and resulting costs and returns per hectare were assessed.

Production per hectare was greatest from crossbred steers at the intermediate stocking rate with either type of fodder conservation.
