Esperance Downs Research Station : Rehabilitation Report, H L. Jones

Resource management technical reports

The overall program objectives were: rehabilitation of degraded areas on the Esperance Downs Research Station to be demonstrated to restore agricultural productivity. Specific degradation issues addressed were salinity, waterlogging and wind erosion. The second objective was the demonstration of sustainable agricultural systems at a farm scale which either slow, halt or reverse land degradation while being profitable. Specific strategies adopted to reclaim land included surface drainage, tree planting,

Sustainable Tourism Plan For The Houtman Abrolhos Islands, Fisheries Western Australia

Fisheries management papers

The Abrolhos coral reefs are the southernmost living reefs in the Indian Ocean. They have a unique assemblage of tropical species of fish, reef corals and other invertebrates, which live in close association with temperate species, particularly of algae, and species endemic to Western Australia. The Abrolhos is the centre of the fishery for the commercially valuable western rock lobster (Panulirus cygnus). Terrestrial flora and fauna of the Abrolhos are relict and provide important reference areas on ecological interactions. Virtually all the islands of the Abrolhos archipelago have sea bird nesting and breeding areas, and populations of some species of …

Profitable Canola Production In The Great Southern And Lakes District, Paul Carmody, Ashley Herbert

Bulletins 4000 -

The Canola industry has rapidly grown with a 10 fold increase in area sown in Western Australia over the four years from 1996-99.

The driving force behind this increase in area can be attributed to the successful adoption of weed control technology in Triazine Tolerant Canola.

By knowing the model of the limiting factors, which are usually; weed control, fertiliser practices, blackleg management, variety selection, seeding dates, seeding depths, insect control and swathing, we can make the right decisions and achieve the targeted profit.

To produce yield to potential, all factors need to be optimised, otherwise yields will be decreased …

Improved Soil Management And Cropping Systems For Waterlog-Prone Soils : Results Of The 1999 Season, Derk Bakker, Greg Hamilton, D Houlbrooke, Cliff Spann

Resource management technical reports

The project aim was to map the distribution of waterlogging occurrences relative to soil type and climate; to develop soil, water and crop management practices applied to the concept of raised beds to alleviate or prevent waterlogging; to establish the economics of raised bed farming, relative to geographic location and waterlogging frequency.

Western Australia Soil Acidity Research And Development Update 2001 : Time To Lime, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

This book for 2001 again summarises the work being carried out by staff of The Integrated Soil Acidity Research, Development and Extension projects in Western Australia. These projects are based at Agriculture Western Australia, The University of Western Australia and CSIRO.

Several articles in this book are an indication that the current round of funding for this work is drawing to a close in June 2002. The articles reflect our increasing understanding of not only the effects of soil acidity but also the time required for current practices of surface applied lime to ameliorate acidity in both the surface and …

Hydrogeological Study Of The Dongolocking Reserves, Dumbleyung, Western Australia, Ben Whitfield

Resource management technical reports

The aims of the hydrogeological study were to assess the characteristics of aquifers within the weathered zone, throughout the Dongolocking Reserves and in the surrounding farmland; provide baseline data on root zone salt store (EM38) and vertical distribution of stored salts (EM38) through the use of ground-based geophysical techniques; identify remnant bush at risk of salinisation; suggest management options to address any observed salinity problems; provide a groundwater monitoring network.

Extent And Impacts Of Dryland Salinity, C E. Mcconnell, R Short

Resource management technical reports

The extent and impact of dryland salinity in Western Australia was based on analysis of groundwater depth and trend and the risk of shallow watertables is derived from these two attributes. As dryland salinity is caused by shallow watertables, the risk of salinity is inferred from the risk of shallow watertables.

Relationships Between Stream Order And Management Priority: A Water Quality Case Study, David Weaver, Adrian Reed, John Grant

Conference papers and presentations

Seagrass, which once dominated the habitat of Oyster Harbour on the south coast of Western Australia has been replaced by macroalgae because of increased nutrient and sediment discharge from the rural dominated catchment. Total Phosphorus (TP), Total Nitrogen (TN), Suspended Sediment (SS) and Electrical Conductivity (EC) concentrations from a catchment – wide (168 sites), event-driven snapshot, water quality monitoring program conducted from 1994 to 1996, were analysed in relation to stream order and published survey data on riparian zone condition. This analysis was performed to examine relationships between stream order, riparian zone condition and water quality, and implications for the …

Before And After Riparian Management: Sediment And Nutrient Exports From A Small Agricultural Catchment, Western Australia, Lucy Mckergow, David Weaver, I Prosser, R Grayson, A. E.G. Reed

Conference papers and presentations

Riparian vegetation can trap sediment and nutrients coming from hillslopes and reduce stream bank erosion. This study presents results from a 10 year stream monitoring program in a small agricultural catchment near Albany, Western Australia. In 1996, a 1.6 km stream reach was fenced, planted with eucalyptus species and managed separately from the adjacent paddocks. Stream flow, nutrient and sediment concentration data were collected at the downstream end of the fenced riparian area between 1991 and 2000, so there are data for the “before” and “after” riparian management periods. Suspended sediment concentrations fell dramatically following riparian management; the average event …

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 …
