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.

This report presents a summary of the key findings from a mailed survey to 2,000 landholders in the South West Region of Western Australia in 2006. The survey gathered information on the key social and economic factors affecting landholder decision-making about the adoption of practices expected to improve the management of natural resources in the region. The response rate for the survey was 69.4%.

The South West Catchment Council, Western Australian Department of Agriculture and Food and the Bureau of Rural Sciences were key project partners. Funding was from a mix of national, state and regional programmes, including the Natural …

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 …

A Land Resource Survey Of The Fall Point Coastline, Broome, W.A., P A. Hesp, P J. Curry

Resource management technical reports

The purpose of this study was to find a suitable location for a bird observatory and provide adequate coastal land resource data for the area. The main selection criteria and conditions were: the location was closely adjacent to major wader roosting and feeding sites; all-seasons access was required; the location provided a site of around 2 1/2 hectares to provide space for one or more buildings, camp ground and associated facilities ; anticipated access tracks, site developments and levels of use.
