Subsurface Compaction A Guide For Wa Farmers And Consultants, Stephen Davies, Alison Lacey

Bulletins 4000 -

For plants to grow in agricultural soils, roots and emerging shoots must be able to force their way through the soil. In soils of high strength, this growth is physically restricted. High strength soils may be due to natural soil characteristics and conditions or develop as a result of agricultural practices and may be in layers or throughout the soil profile.

In agriculture, high strength soils commonly occur as a result of compaction. Compaction of agricultural soils can be in the surface (often caused by stock trampling or rain drop splatter) or in the subsurface (usually in a layer at …

Tree Windbreaks In The Wheatbelt, Robert Sudmeyer, David Bicknell, Neil Coles

Bulletins 4000 -

Windbreaks comprising trees, or tree and shrub combinations, can offer many benefits on wheatbelt farms, particularly for protection of soil, stock, crops and pastures from damaging winds and erosion. Additional benefits include reduced evaporation from farm dams, reduced groundwater recharge, their use as nature conservation corridors and habitats, increased biodiversity including predators of crop and pasture pests, fire control, tree products and improved lifestyle and aesthetics.

In other areas and farming systems such as intensive horticulture, man-made windbreaks may be used, but their higher cost makes them unsuited for broadscale agriculture. Man-made windbreaks can be effective in reducing evaporative losses …

Fertigation Of Vegetables In Western Australia, J Burt

Bulletins 4000 -

Fertigation is the technique of using soluble fertilisers to supply essential nutrients to vegetables through sprinkler or trickle irrigation systems, or by means of a boom spray. It is ideally suited to most horticultural areas in Western Australia, especially the sandy soils of the Swan Coastal Plain that have a poor capacity to retain nutrients.

Before and after planting, nutrients are often applied to vegetables on soils of the Swan Coastal Plain by applications of poultry manure* or solid fertilisers. After planting, fertigation is a safe and effective method of applying top-dressings of nutrients to crops, especially after the rows …

North Stirling Land Conservation District - Soils Manual, Justin Hardy, Peter J. Tille

Soil conservation survey collection

The North Stirling Land Conservation District is located between Katanning and Albany on the northern edge of the Stirling Ranges in south-western Western Australia.It includes parts of the Shires of Cranbrook and Tambellup, covering approximately 100,000ha of the catchment of the North Stirling basin. The basin is a flat area formed on Eocene sediments with poorly defined drainage lines and many salt lakes. It is surrounded by low granite and sandstone hills. The climate is Mediterranean, with cool wet winters and hot dry summers. Average annual rainfall ranges from 375-500 mm per annum. There is very little surface or underground …

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.
