Pasture Condition Guides For The Southern Rangelands, Including The Gascoyne, Murchison And Goldfields-Nullarbor, Peter-Jon A. Waddell, Philip We Thomas, Wayne J. Fletcher, Kath Ryan, Joshua E. Foster, John K. Stretch, Jim S. Addison

Bulletins 4000 -

These guides address a recognised gap in readily applicable and easily accessible information on southern rangelands pasture condition and management.

These guides provide descriptions and images for southern rangelands pastures with similar management requirements for the grazing of native pastures by livestock. Therefore, the focus is on palatability of vegetation to livestock, and the effects of livestock management and external factors on the condition of the vegetation and soils.

The first section provides an overview and map, introduces concepts and terms important to understanding arid shrubland management in general, these guides in particular; and includes an economic analysis of the …

Greener Pastures 1 - The Greener Pasture Project: Managing Nutrients In Dairy Pastures, John Lucey, Mike Bolland, Don Bennett, Richard Morris, Bill Russell, Martin Staines

Bulletins 4000 -

As dairy farmers have strived to maintain profitability, many have farmed more intensively. More cows are milked and increasing inputs of fertiliser and purchased feed are used per hectare. However, these increased nutrient inputs have far exceeded the increase in nutrient output in milk production. The increasing nutrient surplus (inputs minus outputs) from intensification on dairy farms has met with increasing community concern about the environmental footprint of the dairy industry. In some other countries, dairy farmers who have intensified by increasing nitrogen inputs are now faced with legislation controlling the amount of fertiliser nitrogen that they can use.

Lime For High Rainfall Pastures: Above 800mm Average Annual Rainfall, Mike Bolland, Bill Russell

Bulletins 4000 -

Conventional agriculture acidifies soil. As your soil becomes more acid, productive pasture species disappear and are replaced by species of low agricultural value. It is a waste of money to apply expensive fertiliser to pastures which are inherently poorly productive because they are growing in an acid soil.

The paper examines the types of lime available, how to select lime for quality and when and how much lime to apply. Maganese toxity and aluminum toxicity are examine, how to test your soil, and affect of soil acidity on bacteria and other microorgansims.

Climate Change, Vulnerability And Adaptation For South-West Western Australia: Phase One Of Action 5.5, Western Australian Greenhouse Strategy, Luke Morgan, Jo Anne Molin, Ross George, Richard Mckellar, Janet Conte

Selecting And Developing Reliable Bore Sites In The Eastern Wheatbelt, Richard George

Bulletins 4000 -

In the Western Australian wheatbelt, groundwater supplies contribute about 40 per cent of the on-farm livestock requirements and occasionally domestic water supply systems. The first part of this Bulletin comments on sites suitable for both high yielding bores and also those which yield water suitable for livestock. The second part outlines techniques for constructing and developing a bore. Throughout this Bulletin livestock quality water, for adult sheep, is defined as groundwater of less than 12,000 mg/L (or 850 grains per gallon) which has not been subject to localized pollution. For other livestock, the maximum salinities range from 2,600 mg/L for …
