Trees For Windbreaks On Swan Coastal Plain Farms, Leon English, Ken Angell, Metropolitan District Office, Department Of Agriculture And Food, Western Australia Jan 1989

Trees For Windbreaks On Swan Coastal Plain Farms, Leon English, Ken Angell, Metropolitan District Office, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Strong easterly and south-westerly winds are a feature of the Swan Coastal Plain and we receive frequent inquiries about which tree species are suitable for planting as windbreaks. When selecting trees for windbreaks you must match the species to the various soil types which occur along the Coastal Plain. The mature height of the tree is also an important consideration in good windbreak design. This Bulletin lists species which are suitable for windbreaks in descending order of mature height and indicates the soil type(s) on which they should be planted.

The Soils Of The Salmon Gums District, Western Australia, George Henry Burvill Dec 1988

The Soils Of The Salmon Gums District, Western Australia, George Henry Burvill

Technical Bulletins

Most of the soils are grey and brown solonized soils. The subsoils, to about 2 m, are calcareous sandy clays with limestone rubble, but there are three main surface variations: sandy surfaced, 5-30 cm deep, passing abruptly to the sandy clay subsoil with lime nodules. The Circle Valley sand and Scaddan sand are major types. Scaddan sand has a domed subsoil clay. Powdery calcareous sandy loam; and clay loam and clay with some lime in the subsoil, but less than in 1 and 2.


Carlton Plains Soil Survey In The Shire Of Wyndham, East Kimberley, T C. Stoneman Sep 1988

Carlton Plains Soil Survey In The Shire Of Wyndham, East Kimberley, T C. Stoneman

Resource management technical reports

The Carlton Plains covers approximately 11,750 ha midway between Wyndham and Kununurra on the northern bank of the Ord River in the Shire of East Kimberley.

Miscellaneous Production 23/87 - Animal Production In The Spinifex And Shrubland Regions Of Western Australia, D. Burnside Jul 1988

Miscellaneous Production 23/87 - Animal Production In The Spinifex And Shrubland Regions Of Western Australia, D. Burnside

Animal production and livestock published reports

The role of the Rangeland Management Branch is to promote the sustained economic use of the rangeland resource. It provides research and extension services to the pastoral industry, provides advice on the condition of the range resource to Government and provides technical information on rangelands to other rangeland managers. A principal objective to be met in fulfilling that role is the development and promotion of economically efficient place systems that conserve the rangeland resource. At the inaugural Pastoral Soil Conservation Districts Conference in Meekatharra in May 1987, pastoralist delegates emphasized the importance of achieving that objective within the various soil …


The Concept Of Prime Agricultural Land: A Western Australian Perspective, Vivian T. Read Jun 1988

The Concept Of Prime Agricultural Land: A Western Australian Perspective, Vivian T. Read

Resource management technical reports

In the past, resource planning by Government authorities in Western Australia has been concentrated in urban areas. The rural areas were referred to as non-urban and planning outside of country townsites was confined to special rural zones. These zones were determined by the State authority (Town Planning Department) and were intended to limit the extent of farm fragmentation so as to control servicing costs and possible conflict.

The new State Planning Commission is expected soon to introduce the requirement of rural planning strategies for Local Government Areas where demand for land subdivision is high. The strategies will be based on …

Annual Medic Evaluation On Eradu Sandplain Soil - 3 M Rows., Bradley Nutt, M. K. Laslett

Experimental Summaries - Plant Research

Trial 88EC16

Location: East Chapman Research Station

Inoculated and lime pelleted seed was hand sown into 3m rows at 0.25 g/m. All the medics were inoculated with WSM 540 which may have been less effective with some of the M. littoralis and M. tornata varieties. The 1988 season was very good in terms of frequency and amount of rainfall which is reflected in the high seed yields compared to 1987.
