Audit Of Wa Agricultural Lime Quality 2013, Chris Gazey Aug 2013

Audit Of Wa Agricultural Lime Quality 2013, Chris Gazey

Bulletins 4000 -

Applying agricultural lime is the most economical way of ameliorating low soil pH in broadscale agriculture in Western Australia (WA). In WA, agricultural lime is usually limesand from coastal sand dunes, crushed limestone from coastal deposits or crushed dolomitic lime (usually marketed as dolomite) from old lake and inland drainage systems. Other sources are Cretaceous chalk and lake bed marls.

WA agriculture is well serviced by lime suppliers, although the quality of lime varies markedly around the State, and cost does not always reflect quality as measured by neutralising value and fineness. Neutralising value and particle size distribution (fineness) are …


Subsurface Compaction A Guide For Wa Farmers And Consultants, Stephen Davies, Alison Lacey Jan 2011

Subsurface Compaction A Guide For Wa Farmers And Consultants, Stephen Davies, Alison Lacey

Bulletins 4000 -

For plants to grow in agricultural soils, roots and emerging shoots must be able to force their way through the soil. In soils of high strength, this growth is physically restricted. High strength soils may be due to natural soil characteristics and conditions or develop as a result of agricultural practices and may be in layers or throughout the soil profile.

In agriculture, high strength soils commonly occur as a result of compaction. Compaction of agricultural soils can be in the surface (often caused by stock trampling or rain drop splatter) or in the subsurface (usually in a layer at …


Carbon Capture Project, Final Report. An Evaluation Of The Opportunity And Risks Of Carbon Offset Based Enterprises In The Kimberley-Pilbara Region Of Western Australia, Mark Alchin, Elizabeth Tierney, Chris Chilcott Mar 2010

Carbon Capture Project, Final Report. An Evaluation Of The Opportunity And Risks Of Carbon Offset Based Enterprises In The Kimberley-Pilbara Region Of Western Australia, Mark Alchin, Elizabeth Tierney, Chris Chilcott

Bulletins 4000 -

Commercialisation of carbon in the Australian Rangelands could lead to the development of a multi-billion dollar industry, and Western Australia has the potential to capture a significant share of this revenue. A significant proportion of the WA Rangelands is degraded which is the legacy of the exploitative practices of historical pastoral development and the mining industry. Full environmental restoration of these areas is well beyond the fiscal capacity of land managers and the WA State Government. Carbon based enterprises have the potential to restore large tracts of degraded land in a cost-effective manner and can deliver a number of other …


Compost Production And Use In Horticulture, Bob Paulin, Peter O'Malley Jul 2008

Compost Production And Use In Horticulture, Bob Paulin, Peter O'Malley

Bulletins 4000 -

Maintaining and improving soil organic carbon levels is becoming an increasingly important aspect of modern farming. Compost provides potentially one of the most effective ways of applying organic matter to soils and improving organic carbon levels.

Improving soil organic carbon is directly related to soil quality and performance. Increased quality reflects improved biological function (soil health), fertility and physical attributes that include better drainage, reduced compaction and erosion, and improved moisture-holding capability, at least for lighter soils.

Compost is not the only option available. Others include the use of cover or break crops, reducing the use of cultivations, selecting safe …

Alstroemeria, Aileen Reid Oct 2006

Alstroemeria, Aileen Reid

Bulletins 4000 -

About 60 species of Alstroemeria grow wild in South America, in habitats ranging from the snowline of the Andes and high mountain plateaus down through the highland forests to the coastal deserts.

A member of the lily family, Alstroemeria grows from a rhizome that also develops tuberous storage outgrowths and fleshy roots. The aerial shoots can be either vegetative or reproductive. Normally shoots that have unfolded more than 30 leaves will not flower and remain vegetative.

The leaves of Alstroemeria are unusual in that they rotate through 180 degrees as they unfold, so that the upper surface becomes the lower …

Fertigation Of Vegetables In Western Australia, J Burt Jan 2002

Fertigation Of Vegetables In Western Australia, J Burt

Bulletins 4000 -

Fertigation is the technique of using soluble fertilisers to supply essential nutrients to vegetables through sprinkler or trickle irrigation systems, or by means of a boom spray. It is ideally suited to most horticultural areas in Western Australia, especially the sandy soils of the Swan Coastal Plain that have a poor capacity to retain nutrients.

Before and after planting, nutrients are often applied to vegetables on soils of the Swan Coastal Plain by applications of poultry manure* or solid fertilisers. After planting, fertigation is a safe and effective method of applying top-dressings of nutrients to crops, especially after the rows …


Organic Vegetables : A Guide To Production, Steven Mccoy Oct 2001

Organic Vegetables : A Guide To Production, Steven Mccoy

Bulletins 4000 -

There appears to be considerable opportunity for the development of organic vegetable production in Western Australia for either fresh or processed product. While a number of growers are successfully producing relatively small quantities of organic vegetables for both domestic and export markets, few large scale commercial growers have sought to capitalise on this opportunity.

Consumer interest in organically grown vegetables has increased rapidly in recent years due largely to concerns relating to food safety, health and the environment. For more information on markets for organic vegetables refer to AGWEST publication “Market Prospects – Organic Carrots and other Vegetables”.

Organic Grapes And Wine : A Guide To Production, Gerry Parlevliet, Steven Mccoy Jul 2001

Organic Grapes And Wine : A Guide To Production, Gerry Parlevliet, Steven Mccoy

Bulletins 4000 -

The tastebuds, health concerns and environmental conscience of affluent consumers are demanding more organically grown food than producers worldwide can supply. Growing consumer concerns about the effects of synthetic chemical pesticides and fertilisers on human health and the environment have boosted world trade in organic products by a rate of about 20-30 per cent a year for the past 10 years. World trade was estimated to be worth $US 21.6 billion in 2000 and is expected to reach US$100 billion by the year 2006.

The Australian market for organic products alone is valued at $200-$250 million - with exports estimated …
