Western Australia Soil Acidity Research And Development Update 1997 : Time To Lime, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

There is a lot of lime being spread in Western Australia – or is there?

In fact, the Australian Bureau of Statistics agricultural census paints a picture showing that we are still far short of the amount of lime that should be getting on to the ground.

For many years Western Australian soils acidified without significant production penalties. The soil pH was at values that were not affecting plant growth. However, over the last decade or so, large areas of soils have reached the point where production is being affected. In addition, we are now introducing plant species such as …

The Salinity And Hydrology Of The Tambellup Townsite And Jam Creek Catchment, R Ferdowsian, A T. Ryder

Resource management technical reports

The study area covers the Tambellup Town and the Jam Creek Catchment (top photograph on cover). The Tambellup Town is located 115 km north of Albany. The town has a population of 360 people (800 in the whole Shire). Tambellup is experiencing increasing salinity problems. Saline groundwater levels are close to the soil surface and cause deterioration of buildings, roads, infrastructure, death of trees and scalding of land including the sporting grounds. Many hectares of land in the Jam Creek Catchment has become salt-affected and salinity is on increase. The objective of this study was to define the present salinity …

Focus Catchments : A New Approach To Salinity Research : National Dryland Salinity Program, Steve Porritt

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

Dry/and salinity is a major threat to the resource base of many rural industries around Australia. More than 1.8 million hectares of once productive land are affected by salinity, with a further 1.6 million hectares at risk in the next 15 to 25 years in Western Australia alone. Much of the past Commonwealth and State expenditure on salinity programs and activities has been poorly targeted and coordinated. In view of this, a national dry/and salinity program that supports specific State salinity management programs has been established jointly between the Commonwealth and State government agencies.

Soil Assessment Of The West Gingin Area, Henry Smolinski, G G. Scholz

Land resources series

Soils of approximately 80,000 hectares in the West Gingin area, 100 km north of Perth, were surveyed from 1987 to 1989. The area lies on the Swan Coastal Plain within the Gingin Shire. The soils were mapped by the free survey method at a scale of 1:50,000. Thirty-five major soil associations and complexes were identified. These soils have been formed from various parent materials in a a range of depositional environments. Siliceous sand and sodic soils formed in alluvial-lacustrine sediments predominate. The main soils were sampled for chemical and physical analysis and their morphological, chemical and physical properties are discussed …

Images 2.1 : An Integrated Model Of An Arid Grazing System, Z G. Yan, K M. Wang

Resource management technical reports

The name IMAGES stands for An Integrated Model of an Arid Grazing Ecological System. The model was initiated by Dr R. Hacker in 1987-8 as an activity to (1) evaluate alternative management strategies and (2) identify key ecological processes and research priorities in shrub rangelands of Western Australia. Version 1 of the model was published in Agriculture Systems in 1991 (Hacker et al. 1991) and here after will be referred to as IMAGES 1. IMAGES 1 is a vegetation model, capable of predicting the prob ility of recruitment and mortality of the desirable species in a given vegetation type under …

Rex ' 96 : An Expert Guide To Revegetation, David Bicknell

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

Agriculture Western Australia has provided coordination and technical input to a powerful source of information on plants for Australian conditions. David Bicknell outlines some of its features and uses.

Farmers, local government, advisers and even gardeners often have trouble finding the right plant for the right place for a given purpose. Rather than spend a lot of time, money and effort looking through scattered sources of information, many people stick with a limited number of species year after year. This neglects plants that may be much better suited to the purpose, and also fails to develop Australia's huge range of …

Improving Dairy Farm Performance, Ruth Dilley

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

Western Austraian sairy farmers produce more milk per cow and per farm than their eastern Sttates counterparts and the milk is also of higher quality. But there is always room for improvement and as grain prices rise it is crucial that maximum benefit is derived from the cheapest feed source - the pasture.With this in mind Ruth Dilley looks at the Dairy Farm Performance Program - a comprihensive farm database developed by Agriculture Western Australia.

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.

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.
