Vegetation Health Analysis (Peel-Harvey Coastal Plain Catchment) : An Impact Study On The Use Of Alkaloam (Bauxite Residue) As A Soil Amendment On Agricultural Land, Garry Heady, Chris Ferreira Dec 2001

Vegetation Health Analysis (Peel-Harvey Coastal Plain Catchment) : An Impact Study On The Use Of Alkaloam (Bauxite Residue) As A Soil Amendment On Agricultural Land, Garry Heady, Chris Ferreira

All other publications

In 1997, a program was established to monitor the long term, (a minimum of 10 years), impacts on remnant native vegetation, of Alkaloam bauxite residue used as a soil amendment on adjacent agricultural land Data collection is to be repeated on an annual basis for the duration of the program. This report presents pre-treatment site and vegetation data for 2001, the fourth year of sampling in the program. Overall results are compared with those from 1997, 1998 and 2000. Descriptions of monitoring sites and an outline of project design and methodology are provided so the report can be read independently …


Weed Plan For Western Australia, State Weed Plan Steering Group, Department Of Agriculture And Food, Western Australia Oct 2001

Weed Plan For Western Australia, State Weed Plan Steering Group, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

One of the most significant environmental challenges facing Western Australia is the minimisation of the impact of weeds. In the relatively short history of this State since European settlement, some 1155 exotic plant species have established as weeds in our diverse and generally fragile ecosystems. While development for agriculture, mining, transport and housing must by its nature result in some change to the State’s flora, the introduction of weedy plant species has caused serious impacts which cause great concern.

Weeds now pose a serious threat to many of the State’s ecosystems, and impose high annual costs on agricultural industries. Weeds …


Management Of Soil Organic Matter And Gypsum For Sustainable Production In The Carnarvon Horticultural District Of Western Australia, R.S.B. Greene, A.J. Lin, D. C. Parr Mar 2001

Management Of Soil Organic Matter And Gypsum For Sustainable Production In The Carnarvon Horticultural District Of Western Australia, R.S.B. Greene, A.J. Lin, D. C. Parr

Agriculture reports

Soil quality is critically important for the long-term production of high quality and high yielding fruit and vegetable crops in the Carnarvon horticultural district of Western Australia. A stable soil structure is essential for good soil quality.

Soil Factors Influencing Eutrophication. In Soilguide. A Handbook For Understanding And Managing Agricultural Soils. (Ed. Geoff Moore), David Weaver, Robert Summers Jan 2001

Soil Factors Influencing Eutrophication. In Soilguide. A Handbook For Understanding And Managing Agricultural Soils. (Ed. Geoff Moore), David Weaver, Robert Summers

Bulletins 4000 -

Eutrophication is essentially the nutrient enrichment of waterways leading to algal growth. It must be controlled to maintain sustainable agricultural systems and the main mechanisms of control are stabilising catchment processes and reducing nutrient output.

Eutrophication can be defined as 'the nutrient enrichment of waters which results in the stimulation of an array of symptomatic changes, among which increased production of algae and macrophytes, deterioration of water quality and other symptomatic changes, are found to be undesirable and interfere with water uses' (OECD 1982). The word eutrophic is a Greek word that means 'well fed'. The food referred to is …


Soilguide (Soil Guide) : A Handbook For Understanding And Managing Agricultural Soils, Geoff Allan Moore Jan 2001

Soilguide (Soil Guide) : A Handbook For Understanding And Managing Agricultural Soils, Geoff Allan Moore

Bulletins 4000 -

This handbook integrates the current knowledge of soils in south-western Australia in a user-friendly form. It describes how to assess which soil properties influence production and land degradation in the agricultural area and summarises management options to remedy or minimise soil limitations. The potential for growing a large range of crops and pastures can be assessed. In particular, the links between soil morphology, soil properties, management and agronomy are emphasised. The manual is designed for use at the paddock scale or for site assessment, but it can also be used at a catchment or regional scale. It is specifically designed …
