This report aims to provide a summary of national and international activity in the use of agricultural by-products for the production of bioenergy and biofuels. The summary is primarily an internal report for the Department of Agriculture and Food, Western Australia (DAFWA), but will hopefully be of some value to industry proponents that are interested in pursuing the opportunities provided by what are currently low value agricultural waste products. We outline three processes for obtaining energy from these by-products that may be appropriate for the farming sector in Western Australia (WA).

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 …

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 …

Subsurface Acidity, Mike Bolland, Chris Gazey, Amanda Miller, Dave Gartner, Julie-Anne Roche

Bulletins 4000 -

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 …

Successful Field Pea Harvesting, Glen Riethmuller, Ian Pritchard Sep 2003

Successful Field Pea Harvesting, Glen Riethmuller, Ian Pritchard

Bulletins 4000 -

Many thousands of hectares of field peas are harvested trouble free each year. Growers experience together with recent machinery innovations and modifications have solved the majority of harvesting difficulties. Optimum harvesting conditions are in a crop of uniform density on a level soil surface with the machine either working into or across the direction that the crop has been laid by the wind.

To make harvest easier the receival standard for moisture in pulses has been lifted to 14 per cent, which allows harvest to begin sooner when the crop is the range of 14 to 15 per cent moisture. …
