Introduction To Salinity - Workshop Manual For Participants, T M. Lacey
Introduction To Salinity - Workshop Manual For Participants, T M. Lacey
Agriculture reports
This is the first in a series of workshops looking at dryland salinity and options to manage it. These ?Million hectares? workshops have the common themes of environmental improvement. They provide information to help participants identify the risks within the catchment and at a farm level, assess both the likelihood of the risk occurring and consequences if the risk is not managed and determine the best course of action for individual. Participants will determine their courses of action based on their specific circumstances and goals. There is no one recipe that is suited to all participants. The Participants Notes when …

Salinity Investment Framework : Agricultural Land And Infrastructure, Richard J. George Dr, Ross Kingwell, J Hill-Tonkin, R A. Nulsen
Resource management technical reports
Greater awareness of the potential impact of salinity has led to increased public and private expenditure. The Salinity Investment Framework was developed to insert rigour and accountability into decision-making processes and guide future development. This report focusses on the economic impact of salinity on private and public land and the infrastructure of areas in Western Australia, including towns, railway systems, roads and the like.

Avon Hotham Catchment Appraisal 2005, S Sharafi, H Lauk, Paul Galloway
Resource management technical reports
This report summarises current information on risks and impacts to agricultural production and natural resources within the Avon Hotham study area. It then identifies suitable options to manage such risks. The Avon Hotham study area is 1.9 million hectares and is made up of three sub catchments: West Avon, South Avon and Hotham, in south west Western Australia. Among the risks and impacts discussed are rainfall, surface drainage; major land degredation hazards are subsurface compaction and acidification.

Land Evaluation Standards For Land Resource Mapping : Assessing Land Qualities And Determining Land Capability In South-Western Australia, Dennis Van Gool, Peter J. Tille, Geoff Allen Moore
Resource management technical reports
This report describes the standard method for attributing and evaluating conventional land resource survey maps in the south-west agriculture region of Western Australia so that strategic decisions about the management, development and conservation of land resources can be based on the best information available. The standards described are similar to the land suitability assessment (stage one of the two stage) methods described by the Food and Agriculture Organisation (FAO, 1976, 1983).

Access And Allocation Arrangements For The Commercial 'Wetline' Fisheries. Proposals For Discussion., Commercial Access Panel
Access And Allocation Arrangements For The Commercial 'Wetline' Fisheries. Proposals For Discussion., Commercial Access Panel
Fisheries Management Papers
The Minister for Fisheries established this review of open access (wetline) commercial fishery arrangements to provide a more effective management framework for wetline fishing and to complement the recreational initiatives. This must involve the removal of excess fishing capacity, including latent effort, from the fishery and the establishment of a dedicated commercial fishery with clear entry criteria and an appropriate limit on catch in each bioregion. However it must be made clear that the ‘wetline review’ is not a sectoral resource sharing exercise. Following the implementation of new management arrangements for the ‘wetline’ fisheries, the appropriateness of the existing levels …

Proposed Management Arrangements For The Gascoyne Commercial 'Wetland' Fishery. A Discussion Paper., West Coast And Gascoye Wetline Review Management Planning Panel.
Fisheries Management Papers
The ‘Wetline Review’ was established to implement an effective management framework for the commercial sector to complement the recreational initiatives. It must be stressed at the outset that this review is focussed on the take of scalefish by the commercial sector. The existing levels of use between the various user groups in the Gascoyne will be examined under the new integrated fisheries initiative following the implementation of new management arrangements for scalefish taken by the commercial sector.

An Inventory Of Rangelands In Part Of The Broome Shire, Western Australia, W E. Cotching
Technical Bulletins
The inventory of rangelands in part of the Broome Shire in Western Australia was undertaken by DAFWA between 1989 and 1990. It describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The survey of part of the Broome Shire …
Silcrete Hardpan In The North-Eastern Wheatbelt : Hydrological Implications For Oil Mallees, D L. Bennett, Russell Speed, Adrian Goodreid, Peter Taylor
Silcrete Hardpan In The North-Eastern Wheatbelt : Hydrological Implications For Oil Mallees, D L. Bennett, Russell Speed, Adrian Goodreid, Peter Taylor
Resource management technical reports
Silcrete is a brittle, intensely indurated rock comprising primarily quartz grains cemented with siliceous allophane. It occurs at 1.5 to 7 metres deep and is often several metres thick and extremely hard, requiring excavation. This Report discusses the extent of silcrete layers in the north-eastern wheatbelt area of Western Australia, the effects of silcrete on water absorption by the soil, and the effects of this physical obstacle on the growth and expansion of oil mallee trees of the region.

Mole Drainage For Increased Productivity In The South West Irrigation Area, D L. Bennett, Richard George, Bill Russell
Mole Drainage For Increased Productivity In The South West Irrigation Area, D L. Bennett, Richard George, Bill Russell
Bulletins 4000 -
Heavy soils, with low rates of soil-water movement, such as those found in the South-West Irrigation Area (SWIA), require closely spaced (2-6 m apart) subsoil drainage systems to provide sufficient water movement to control the effects of salt-waterlogging on pastures. Such close spacing using traditional buried pipe or tile drainage systems is impractical. As a result, mole drainage systems, used in other parts of the world for over 50 years, have gained popularity in the SWIA in recent years.
This Bulletin Farmnote reports the current ‘best-bet’ mole draining technique for SWIA conditions gathered from observations over a number of years …

Gross Margins Guide 2005 Western Australia, Allan Herbert
Farm Systems and Economics published reports
The Western Australian Department of Agriculture has prepared this 2005 booklet with the following aim:
To provide budgeting information for farmers, agribusiness, and other students of agriculture to enhance understanding and more informed decision making.
It builds on a previous similar booklet - "Gross Margins Guide 2003" - which was produced in 2002 with Commonwealth Bank sponsorship. 2,500 copies of that booklet were produced and gained wide readership. Gross margins for broad area agriculture had not been published by the Department for the previous 1 O years. Feedback and further requests suggested that an update was necessary - hence this …
Key Grazing Levels (Foo Targets) For Pasture And Sheep Management, Department Of Agriculture, Western Australia
Key Grazing Levels (Foo Targets) For Pasture And Sheep Management, Department Of Agriculture, Western Australia
Animal production and livestock published reports
Food On Offer (FOO) is the amount of pasture in front of an animal, and is measured in kilograms Dry Matter per hectare. Managing pastures to key grazing levels - or FOO targets - can result in improved production of grazing systems in Mediterranean environments which are characterized by slow winter growth, peak spring growth and dry summers. These targets vary according to what production response is required.
This information sheet illustrates key target FOO for sheep grazing annual pastures during autumn and spring.
