In November, the Premier of Western Australia, Richard Court, released his governments strategy to tackle one of the State's most serious environmental problems - salinity. This article provides a summary of the action plan, full details are available in a two volum set 'Salinity - a situation statement for Western Australia' and 'Western australian salinity action plan'.

Soils Of The Knox Creek Plain East Kimberley Western Australia And Northern Territory, C Grose, Noel Schoknecht

Resource management technical reports

An assessment of the soils and landforms of approximately 12,000 ha in the Knox Creek Plain in Western Australia and the Northern Territory was conducted in May and June 1994. Seventeen map units were identified and their soils, landform and vegetation characteristics were described. Grey or brown cracking clays predominate on the plain, however variable red or brown soils on the coarser alluvium of remnant levees are common in the south and south-east.

Geraldton Region Land Resources Survey, L Gary Rogers, National Landcare Program (Australia)

Land resources series

This report presents results from soil and landform mapping at a scale of 1:250,000 for approximately 2.1 million hectares of the wheat-sheep belt of Western Australia. The study area corresponds with the Geraldton advisory district for Agriculture Western Australia and is the northern extent of the wheatbelt. The area covers parts of three major geological regions of Western Australia: the Perth Basin, Carnarvon Basin and the Yilgarn Craton. Fifty-one soil-landscape systems have been identified, some of which have been divided into subsystems, and are illustrated on the accompanying maps. The landform, parent material, rainfall, land use, native vegetation and soils …

No-Till Sowing : Helping To Keep Cropland Soils In Place, Kevin Bligh, Paul Findlater

Journal of the Department of Agriculture, Western Australia, Series 4

Repeated erosion of tilled land can ;ower crop and pasture yields because of reduced available moisture and nutrient storage. Kevin Bligh and Paul Findlater look at the causes of water and wind erosion and the role of no-till sowing in minimising erosion.

Soils Of The Weaber Plain, East Kimberley, Western Australia, J C. Dixon

Resource management technical reports

The Weaber Plain, north-east of Kununurra, is one of three "black soil" plains in the Kimberley area of Western Australia. It comprises about 15,000 hectares of irrigable land, part of which is known as Stage 2 of the Ord River Irrigation Area (ORIA). The area was surveyed in 1977 following a similar survey of the nearby Keep River Plain and preceding a survey of the Ivanhoe Plain, which has since been developed commercially. Map units and soil series used in those reports have also been used for this rep ility in crop selection, preferring high water use crops.

Soils Of The Mantinea Loop Ord River Valley East Kimberley Western Australia, N Schoknecht, C Grose

Resource management technical reports

A brief assessment of the soils of 1,186 hectares in the Mantinea Loop, and their suitability for irrigated agriculture, was conducted in June 1994. Four map units based on soil, landform and vegetation were identified. The soils are mainly calcareous brown fine sandy loams. The landform is an alluvial plain, with numerous small depressions and channels caused by the meandering and flooding of the Ord River.

Wellington-Blackwood Land Resources Survey, Peter J. Tille, Georgina Wilson, National Landcare Program (Australia)

Land resources series

This report presents descriptions to accompany land resource maps of the Wellington- Blackwood district, east of Bunbury in the south-west of Western Australia. The maps cover an area of about 760,000 hectares and are presented as two map sheets at a scale of 1:100,000. Four different physiographic zones cover the survey area: • The Western Darling Range Zone occupies the major portion of the area and consists of a deeply dissected lateritic plateau overlying crystalline rocks. Three soil-landscape systems containing 24 subsystems have been identified and mapped within this zone. • The Eastern Darling Range Zone is in the south-east …

Each sheet summarises information on the soil's characteristic properties, and associated land use suitability and management. A photograph of a representative profile is provided for each soil. Technical terms are defined in soil sheet glossary. Information is presented under the following headings: soil series and groups, occurence, native vegetation, soil profile description, characteristic soil properties, soil classification and agricultural land use and management.

Land Capability Assessment For The Wellington-Blackwood Survey, Peter J. Tille

Resource management technical reports

This report has been produced to provide more detail on the land capability assessments presented in the Wellington-Blackwood Land Resources Survey (Tille 1996). In that report, the land capability of each of the soil-landscape subsystems has been summarised with a brief description. Capability ratings are provided here for each of the map units (including subsystem phases) which appear on the two map sheets (Tille et al. 1996) accompanying the Wellington-Blackwood Land Resources Survey.

Soils Of The Mount Beaumont Area, G G. Scholz, Henry Smolinski

Land resources series

Mount Beaumont Mount Beaumont is approximately 100 km north-east of Esperance in the south-east of Western Australia. In 1982 an area of 35,000 ha of virgin Crown Land was released for agriculture (identified as Mount Beaumont Stage I) and later it was proposed to release a further 33,600 ha (Mount Beaumont Stage II). Following development of the first stage, doubts arose about the suitability of the soils for agriculture, so the Department of Agriculture (now Agriculture Western Australia) surveyed the soils of the Mount Beaumont Stage II area before further land release. The survey indicated severe limitations to production and …

Soils Of The Ivanhoe West Bank East Kimberley Western Australia, C Grose, N Schoknecht

Resource management technical reports

A brief assessment of the soils of 2,064 ha of land on the Ivanhoe West Bank and their suitability for irrigated agriculture was conducted in May-June 1994. Sandy or loamy soils occur on broad levees adjacent to the Ord River, and areas of 'black soil' and 'red soil' plains occur behind these levees. Some areas of the red soil plain and levees are deeply dissected, and occasional active erosion is evident.

Degradation Of Remnant Vegetation, Richard George, Don Mcfarlane, Russell Speed

Journal of the Department of Agriculture, Western Australia, Series 4

Remnant vegetation, wetlands and riverine systems on both private and public land throughout south-western Australia are being rapidly degraded by dryland salinity, inundation, silting, nutrient enrichment and weed invasion. Richard George, Don McFarlane and Russel Speed outline some of the reasons why this is happening and provide some case studies that highlight actions to protect these remnants.
