Carbon Farming In Relation To Western Australian Agriculture, Robert Sudmeyer, Jackson Parker, Tanmoy Nath, Ananda Ghose Jan 2014

Carbon Farming In Relation To Western Australian Agriculture, Robert Sudmeyer, Jackson Parker, Tanmoy Nath, Ananda Ghose

Bulletins 4000 -

Carbon farming activities need to return multiple economic and environmental co-benefits to be attractive to land managers.

Agriculture Futures: Potential Rural Land Uses On The Palusplain, Rodney Safstrom, Nicolyn Short Dr Feb 2012

Agriculture Futures: Potential Rural Land Uses On The Palusplain, Rodney Safstrom, Nicolyn Short Dr

Resource management technical reports

The purpose of this project was to identify agricultural land use options and opportunities within the Serpentine–Jarrahdale and Murray Shires, with particular focus on the Palusplain wetland section. The report will contribute to the Department of Planning’s natural resource management plan for the region and guide development of regional and local planning strategies. Historically, the Palusplain was a slowly moving, interconnected, seasonal wetland system with areas of higher ground. Extensive clearing and drainage occurred in the late 1800s through to the mid-1900s to facilitate agriculture; however, agriculture has been found to be a major contributor of nutrients to the system. …


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 …

Subsurface Acidity, Mike Bolland, Chris Gazey, Amanda Miller, Dave Gartner, Julie-Anne Roche Feb 2004

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 …

Paired Site Sampling For Soil Carbon Estimation – Western Australia, Edward Arnold Griffin, W H. Verboom, D G. Allen Feb 2003

Paired Site Sampling For Soil Carbon Estimation – Western Australia, Edward Arnold Griffin, W H. Verboom, D G. Allen

Natural resources research reports

This report describes a detailed paired site study at nine locations in the drier parts of south–western Australia representative of areas most recently cleared for agriculture. The pairing was of uncleared, short-term cleared and long-term cleared sites. The study provided samples for modelling soil organic carbon fluxes by CSIRO Land and Water. Analysis and interpretation of results from the samples collected and detailed soil morphology descriptions provide comprehensive documentation of the soil carbon and other soil parameters. This provides a basis for better understanding factors influencing soil carbon dynamics in soils in Western Australia, particularly in areas with sandy topsoils. …

Avoiding The “Fat” Of The Land: Case Studies Of Agricultural Nutrient Balance, David Weaver, Simon Neville Jan 2003

Avoiding The “Fat” Of The Land: Case Studies Of Agricultural Nutrient Balance, David Weaver, Simon Neville

Journal articles

Let’s start with a simple analogy: if a person eats more than they need, they gain weight. That is: if our feed inputs (kilojoules in) are greater than our outputs (exercise — kilojoules out) then we will gain weight (kilojoules in storage).That’s our fat. If, on the other hand, our feed inputs are less than our outputs, then we will lose weight.And if our inputs are the same as our outputs, our weight will remain constant. In general, the further away you are from an ‘ideal’weight, the greater the health risks. And yes, other aspects of your body management — …

Agricultural Progress On The Ord, D A. Mcghie Jan 1986

Agricultural Progress On The Ord, D A. Mcghie

Journal of the Department of Agriculture, Western Australia, Series 4

This is the first of occasional articles describing the experimental and commercial activity on the Ord River Irrigation Area (ORIA) in Western Australia's Kimberley region.

Against a background of extensive recources of land and water, a sometimes cimatic advantage and a complementary disadvantage of a remote location, agriculture on the Ord has swung from various monocultures to a broadly based and diversified production. In 1986, the value of agricultural production on the Ord will approach values equivalent to those of the cotton era for the first time since the demise of that industry 12 years ago.
