Productive agriculture increases the concentration of hydrogen ions in soil, which acidifies the soil.

Aluminium is a component of many soil constituents, including clays and oxides, and is also present on the surfaces of soil organic matter. As the concentration of hydrogen ions in soil increases, soil pH decreases, and aluminium starts to dissolve from the soil constituents, increasing the concentration of aluminium ions in soil solution.

As the concentration of aluminium ions in the solution increases, the aluminium in the soil solution becomes increasingly toxic to plant roots, reducing root growth. The smaller amounts of plant roots explore a …


Tramline Farming Systems Technical Manual, Bindi Webb, Paul Blackwell, Glen Riethmuller, Jeremy Lemon Feb 2004

Tramline Farming Systems Technical Manual, Bindi Webb, Paul Blackwell, Glen Riethmuller, Jeremy Lemon

Bulletins 4000 -

Tramline farming improves farm production and efficiency by controlling traffic and confining compaction to permanent tramlines and reducing overlap. This manual will help you develop your farming system to get the tramline farming benefits. The manual contains information on the principles and techniques of implementing a tramline farming system. There are many options available, so you can tailor the system to suit your own farm.

In eastern Australia, controlled traffic farming (CTF) is another term used for permanent wheel track farming. The system is based on bare, straight tramlines. The term tramline farming is more commonly used in Western Australia …


Topcrop W.A. State Focus 2002-2003 Wheat Protein, Alison Slade, Jeremy Lemon Jan 2004

Topcrop W.A. State Focus 2002-2003 Wheat Protein, Alison Slade, Jeremy Lemon

Bulletins 4000 -

The State Focus program is supported by the Grains Research and Development Corporation (GRDC) in conjunction with TOPCROP to provide grower groups with a new learning concept. The concept was developed in Victoria and has been adopted by South Australia and Western Australia.

Wheat protein was selected as the Western Australian State Focus in response to a wide-ranging consultation of grower groups, researchers and the TOPCROP West management group. As crop yield potential increases through matching varieties to growing season length, weed and disease control, and timely sowing systems, the crop’s demand for nitrogen increases. Unless the demand is matched …

Common Insect Pests And Diseases On Vegetables In The Home Garden, Harald Hoffmann, Stewart Learmonth, Peter Wood Jan 2004

Common Insect Pests And Diseases On Vegetables In The Home Garden, Harald Hoffmann, Stewart Learmonth, Peter Wood

Bulletins 4000 -

Home gardeners frequently see insect pests and diseases affecting their vegetables. Usually they would have seen them in previous seasons, and the symptoms look familiar. However, there are occasions, when an unusual pest (not native to Western Australia) can occur. Exotic pests are a concern for the farming community, as they could threaten the agricultural and horticultural industries and increase the price of production and cost to the consumer.

This bulletin describes the most common insect pests and diseases in home vegetable gardens.


Table Grapes From Western Australia At A Glance, Ian Cameron, Geraldine Pasqual Jan 2004

Table Grapes From Western Australia At A Glance, Ian Cameron, Geraldine Pasqual

Bulletins 4000 -

The high quality of Western Australian table grapes commands premium prices on both domestic and international markets. The industry has grown rapidly from 1992 to 2004, with production increasing from 2200t to 6500t and exports increasing rapidly from about 100t in 1992 to 1320t in 2003. Western Australia produces about 5 per cent of Australian table grapes.

About 300 commercial table grape vineyards are located near the Western Australia coast, extending from the Gascoyne region in the north of the State, including Carnarvon, to the South-West region, including Harvey, Donnybrook, Margaret River and Busselton areas.
