Western Australian Natural Resource Management Plan 09, Department Of Agriculture, Western Australia

Natural resources published reports

The purpose of the State Natural Resource Management [NRM] Plan is to communicate the direction for sustainably managing Western Australia's natural resources.

This direction has been informed by previous initiatives such as the 'Decade of Landcare', several programs focused on salinity, the Western Australian State Sustainability Strategy (2009), and more recently a report commissioned by the State entitled The delivery of Natural Resources Management in Western Australia - a review (2006), which recommended preparation of an NRM Plan. The review noted that the most important issue for the State to clarify first was the outcome it seeks rather than how …

Report On Polyacrylamide, A Practice To Reduce Sediment And Insoluable Chemicals In Tailwater, Tara Slaven Jan 2009

Report On Polyacrylamide, A Practice To Reduce Sediment And Insoluable Chemicals In Tailwater, Tara Slaven

Bulletins 4000 -

The main barrier to the adoption of PAM seems to the timing of the cost of outlay. This could add significantly to the initial crop establishment costs at a time of year when rowers receive no income. However, the partial and parametric analysis indicates that there re benefits from using PAM as part of the crop management cycle. These benefits are from ving water, retaining sediment on-farm and reducing the cost of delving drains. There are ther potential economic benefits including the retainment of phosphorus as a plant nutrient n-farm and subsequent yield increases.

Additionally, the off-site environmental impacts seem …

Plan To Support Grains Industry Development 2009-2012, Department Of Agriculture And Food, Western Australia

Grain and other field crops published reports

The Plan to Support Grains Industry Development (‘the Plan’) recognises that Western Australian agricultural industries are integral to the economic wellbeing of regional and rural communities. The Plan promotes a progressive and profitable grains industry through modern best practice services and research to enhance continuous improvement in farming and supply chain practices.

The Plan has been developed to align with the Government of Western Australia’s initiatives, strategies and tactics for ‘making every hectare count’ (see Appendix 1) and with grains industry needs as identified by industry stakeholders during a series of consultation forums. These industry needs will be addressed in …


Fisheries Research Report No. 182 - A Likelihood Analysis Of Non-Indigenous Marine Species Introduction To Fifteen Ports In Western Australia, Justin I. Mcdonald Dec 2008

Fisheries Research Report No. 182 - A Likelihood Analysis Of Non-Indigenous Marine Species Introduction To Fifteen Ports In Western Australia, Justin I. Mcdonald

Fisheries Research Reports

As an island continent, Australia is heavily dependent upon maritime transport with over 95% of its imports and exports transported by ship (Australian State of the Environment Committee, 2001). With about one third of Australia’s coastline, Western Australia ranks fourth of the six states and territory in the number of known non-indigenous marine species.

In this study fifteen ports in Western Australia were assessed on the potential for non-indigenous marine species to become introduced through ballast water and biofouling. The overall vesselmediated incursion risk to Western Australian ports was calculated by summing the relative incursion threat posed by visits to …

Fisheries Occasional Publication No.72 - Western Rock Lobster Ecological Effects Of Fishing Research Plan., Rhys Brown

Fisheries Occasional Publications

The commercial West Coast Rock Lobster Fishery (WCRLF) targets the western rock lobster (WRL), Panulirus cygnus, averaging approximately 10,000 tonnes of lobsters each year. Currently approximately 450 to 500 boats operate in the Fishery in waters ranging from 5 m to 200 m depth adjacent to the Western Australian coast and stretching from Cape Leeuwin in the south to Shark Bay in the north. The Fishery is managed by the Department of Fisheries (DoF) in Western Australia, using an input control system designed to constrain exploitation/fishing effort and deliver sustainable catches. The annual value of the catch is estimated at …

Fisheries Research Report No. 181 - Developing Long-Term Indicators For The Sub-Tidal Embayment Communities Of Cockburn Sound, Danielle Johnston, C. Wakefield, A Sampey, J Fromont, D C. Harris Oct 2008

Fisheries Research Report No. 181 - Developing Long-Term Indicators For The Sub-Tidal Embayment Communities Of Cockburn Sound, Danielle Johnston, C. Wakefield, A Sampey, J Fromont, D C. Harris

Fisheries Research Reports

Swan Catchment Council Project – 01-0506 T 2006 – 2008 program

The geomorphology of Cockburn Sound is unique to the lower west coast of Australia due to the relative paucity of sheltered nearshore marine embayments along this coastline. Numerous studies on many of the commercially and/or recreationally important species that inhabit Cockburn Sound have demonstrated that for many of them this marine embayment constitutes an integral part of their life history. Since the commencement of industrial and urban development in the mid 1950s, in the waters and along the shores of Cockburn Sound, the marine fauna utilising this area have …


Optlime, A Bioecenomic Model Of Soil Acidity Management In Agricultural Systems, Chris Gazey Sep 2008

Optlime, A Bioecenomic Model Of Soil Acidity Management In Agricultural Systems, Chris Gazey

All other publications

Optlime is a model that represents the essential biological, physical and economic factors related to soil acidity management in Western Australia. The model allows users to define site and soil characteristics for an acidic scenario and then simultaneously assess likely outcomes for 2 different lime sources and application strategies. With and without liming scenarios are examined over a 20 year simulation so as to capture the long-term impacts of soil acidity management. Output provided allows you to examine the likely effect of liming on pH, exchangeable aluminium, yields, and profits. An investment appraisal is provided to show you how liming …


Lime For High Rainfall Pastures: Above 800mm Average Annual Rainfall, Mike Bolland, Bill Russell Sep 2008

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.
