Fisheries Research Contract Reports
Report to the Water Corporation of Western Australia
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 …

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 …

A Model Of Employment Literacy: Young People In Western Australia, Katherine F. Britton
A Model Of Employment Literacy: Young People In Western Australia, Katherine F. Britton
Theses: Doctorates and Masters
This exploratory study aimed to examine the meanings of employment literacy among young people undertaking vocational education or training (VET), trainers, funding representatives and employers in Western Australia. A further objective was to develop a model of employment literacy that would inform training or educational organisations. Employment literacy incorporates the personal and social dimensions that young disadvantaged people require to secure and maintain employment. It also includes the understandings and capacity to access infonnation from a variety of sources and negotiate with a range of people in employment related settings. In-depth interviewing was the main method used so that different …

Grouping & Regrouping Using Mixintools: An Exploratory Study, Richard G. Berlach, Keith Mcnaught
Education Conference Papers
On a regular basis, teachers find it necessary to place children into groups for instruction. Random assignment is typically the norm when group composition is immaterial to the task. When member-sensitive groups need to be created, teachers might associate specific assignment with colours, numbers or other coding systems. Mixintools offers the teacher a strategy for creating groups in an enjoyable, expedient and variable fashion. Or does it? The purpose of this research was to determine whether the resource had any value from the perspective of both the teacher and the student. Data were sourced from three primary schools and one …

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.

Maintaining and improving soil organic carbon levels is becoming an increasingly important aspect of modern farming. Compost provides potentially one of the most effective ways of applying organic matter to soils and improving organic carbon levels.
Improving soil organic carbon is directly related to soil quality and performance. Increased quality reflects improved biological function (soil health), fertility and physical attributes that include better drainage, reduced compaction and erosion, and improved moisture-holding capability, at least for lighter soils.
Compost is not the only option available. Others include the use of cover or break crops, reducing the use of cultivations, selecting safe …
