Esperance Area Acid Sulfate Soil Hazard Mapping, Paul Galloway, Simon Clarendon
Resource management technical reports
This project created a regional scale (1:100 000) acid sulfate soil (ASS) hazard map for the Lake Warden and Esperance town areas, using a combination of existing soil-landscape mapping information and elevation data, supported by field observations and laboratory data from 18 soil cores and 29 additional borelogs with descriptive information useful for identifying ASS and potential ASS materials. All data gathered during this project used common standards and protocols developed in Australia for identifying and mapping ASS materials. The project extends the mapping for acid sulfate soil in the region, complementing existing maps compiled for other parts of the …
Fisheries Management Paper No.245 - Aquaculture Of Coral, Live Rocks And Associated Products. Aquaculture Policy, Department Of Fisheries, Western Australia
Fisheries Management Paper No.245 - Aquaculture Of Coral, Live Rocks And Associated Products. Aquaculture Policy, Department Of Fisheries, Western Australia
Fisheries Management Papers
Aquarium enthusiasts use corals, live rock and associated products (e.g. live sand) for display and to maintain healthy water quality conditions in their marine aquariums. There is a large and growing market for these products. While the wild harvest fisheries for aquarium products in Western Australia are sustainably managed, output is capped, so increased product is needed to meet the market demand. With a trend towards the capping of wild harvest and additional pressures, such as the introduction of Marine Parks and other marine protected areas, the aquaculture of these products is set for industry development and expansion.
The large …

This report describes the fishes and freshwater crayfishes of the Donnelly and Warren River catchments and provides a risk assessment to these fauna of the proposed extraction of water from Record Brook (tributary of the Donnelly River) and subsequent transfer to Scabby Gully Dam (Warren River catchment). The proposed location of the structure in Record Brook is at the gauging station ~1 km upstream from the confluence with the Donnelly River. The project aims to divert peak flows in the winter and spring flow period, transferring around 500 ML each year. The …
Soil Ph In Northern And Southern Areas Of The Wa Wheatbelt, Chris Gazey, Joel Andrew
Soil Ph In Northern And Southern Areas Of The Wa Wheatbelt, Chris Gazey, Joel Andrew
Bulletins 4000 -
More than 80% of the topsoils sampled fall below the critical surface pHCaCl2 of 5.5 in the northern and southern wheatbelt study areas, with more in the south than the north. These results confirm soil acidity is a serious concern throughout the WA wheatbelt when considered in conjunction with the more intensive analysis of current soil pH throughout the Avon River Basin (2005–2008).
With low topsoil pH, it is likely that subsurface acidity is also a problem. For soil acidity to be managed, subsurface pH also needs to be known. In the Avon River Basin study, about half of the …

Survey Of Western Australian Agricultural Lime Sources, Chris Gazey, Dave Gartner
Bulletins 4000 -
As a service to WA wheatbelt farmers, to assist with cost effective management of soil acidity, a survey of agricultural lime availability and quality was conducted by the Department of Agriculture and Food, Western Australia.
The quality of agricultural lime surveyed varied widely between pits. High quality lime is available from limes and, limestone and dolomite sources. Twice as much of the lowest neutralising value lime surveyed would need to be applied compared to the highest to achieve the same increase in soil pH. Limes also varied in the distribution of particle sizes. Selecting limes with a high proportion of …

The Ord River Irrigation Area (ORIA) has a 'flow through' irrigation system. That is, irrigation water is diverted from Lake Kununurra and any waste water from the irrigation system and farms flows directly back into the river downstream. This means that any sediment, nutrient or chemicals in tailwater from farms flows straight into the river.
The Ord Land and Water Management Plan 2000 specifies goals to improve surface water quality. The goals are to reduce the load of chemical and nutrient contamination and sediment in tailwater by 40 per cent.
The aim of this project was to develop and demonstrate …

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 …
