Review Of Land Capability Assessment For The Swan Valley, Peter Tille, Angela Stuart-Street
Review Of Land Capability Assessment For The Swan Valley, Peter Tille, Angela Stuart-Street
Resource management technical reports
Land capability review for the Swan Valley.
The land capability review of the Swan Valley examined and updated previous soil and capability studies done in the area, which are still considered highly relevant for the planning requirements of the Swan Valley. As a result we have updated information on the potential for irrigated agriculture in the Swan Valley which will guide decision-making in the future.
This review uses a modified version of a new approach to presenting information for land use planning, developed by DAFWA in the Mid West region.
The main findings of the review include:
- The alluvial terraces …
The Balancing Act, David Weaver
The Balancing Act, David Weaver
Conference papers and presentations
Nutrient management is as much a global issue as a local one with a balance required between economics and environment, inherent biological limitations and expectations of nutrient use efficiency, and traditional fertiliser practices and actual enterprise nutrient requirements. The concept of nutrient balance depends on context and scale. Nutrient balance can be considered at a global scale, where issues of nutrient stocks, cycles, depletion and transfer of a particular element are important. For a single farm enterprise, nutrient balance might be considered in terms of phosphorus (P) inputs into and outputs from the enterprise. This is commonly known as a …
Wheatbelt Waterwise = Saltwise : Gardening Guide, John Colwill, Juana Roe
Wheatbelt Waterwise = Saltwise : Gardening Guide, John Colwill, Juana Roe
Bulletins 4000 -
As a result of agricultural clearing, many country towns are now feeling the effects of rising groundwater and the salt that it carries. Salinity has been identified as Australia’s number one environmental problem. While most people think that salinity means land lost to agriculture, it also poses a serious threat to many country towns. A report for the Department of Agriculture in 2001 highlighted the need for simple and cost-effective salinity management strategies to be adopted in wheatbelt towns. These included water recycling, revegetation and more efficient water use.

The Busselton Wetlands are a chain of wetlands that lie parallel with the coastline of Geographe Bay, Western Australia and in close proximity to the town of Busselton. The main issues for the maintenance of quality of the wetlands are nutrient levels and habitat value. This guide outlines many of the current best practices related to farming around wetlands.
Scott Coastal Plain A Strategy For A Sustainable Future, Department Of Agriculture And Food, Western Australia
Scott Coastal Plain A Strategy For A Sustainable Future, Department Of Agriculture And Food, Western Australia
Bulletins 4000 -
The Scott Coastal Plain has significant attributes that make it an area of State and regional significance for agricultural production. The climate, availability of good quality groundwater for irrigation, and large lot sizes provide opportunities for mechanised horticultural production which other parts of the State may not have.
An estimate of the area that could be used for each agricultural land use has been developed, at a broad study area level. The figures presented in this report show that diversified production combining tree plantation and/or irrigation (cropping or hay/silage) with grazing enterprises provides for potential increases in gross margins and …

No-Tillage Sowing Decreases Water Erosion On Loamy Soils And Increases Earthworm Activity, Kevin Bligh
No-Tillage Sowing Decreases Water Erosion On Loamy Soils And Increases Earthworm Activity, Kevin Bligh
Journal of the Department of Agriculture, Western Australia, Series 4
No-tillage sowing places seed and fertiliser in the soil without loosening all of the topsoil. Soil is cultivated only in the sown rows, leaving the inter-row areas largely undisturbed.
No-tillage sowing reduces both wind and water erosion. Soil structure is generally improved, and pasture regeneration is increased because seed is not buried too deeply for re-establishment.
Two long-term trials were establis_hed on loamy soils to determine effects of tillage and cropping on runoff and soil loss.

Results Of Stubble Research In Western Australia, Michael Perry, Ron Jarvis, Mel Mason, David Tennant
Journal of the Department of Agriculture, Western Australia, Series 4
Few farmers would question the desirability of retaining stubbles, both for control of erosion by wind and water, and to return organic matter to the soil. While the present debate is focused on the short term management of stubbles, longer term effects also need to be considered.
The Department of Agriculture has several long-running trials intended to measure long term effects.
Red Kangaroos Can Set Back Range Regeneration, Andrew Mclaughlin
Red Kangaroos Can Set Back Range Regeneration, Andrew Mclaughlin
Journal of the Department of Agriculture, Western Australia, Series 4
After years of severe drought, stocking rates in Western Australia s arid rangelands have been kept low since the 1970s to allow native pastures to regenerate. As well, extensive re-seeding programs have started and sheep and cattle grazing on these areas has been restricted or eliminated. However, pasture regeneration in the rangelands can only succeed when grazing by all animals - sheep, cattle, kangaroos, goo.ts, camels, brumbies and donkeys - is controlled Many more red kangaroos roam throughout Western Australia's pastoral areas today than 20 years ago. The installation of windmills and troughs to water domestic livestock has allowed kangaroo …

How To Reduce Spending On Land Conservation, Tim Negus
Journal of the Department of Agriculture, Western Australia, Series 4
Heavy spending on capital works for land conseroation is usually out of the question in the present financial climate, but the recession does not mean that landcare must be abandoned. There are many aspects of landcare that involve little or no extra cost. Soil conseroationist Tim Negus discusses them in this article.
Coastal Plains : Land Use And The Environment, P R. George
Coastal Plains : Land Use And The Environment, P R. George
Journal of the Department of Agriculture, Western Australia, Series 4
Five years ago, this Journal of Agriculture reported on ways to overcome severe algal pollution of the Peel-Harvey estuarine system, 70 km south of Perth.
Several articles in this Journal of Agriculture discuss improved agricultural practices on the Swan Coastal Plain in particular, although the principals will apply to similar eutrophication of the Slbany harbours, Wilson Inlet and the Vassee-Wonnerup Estuary. They also emphasixe the fine balance between man's demand for potable water and land for rural, industrial and urban use.
Gypsum Use In The Wheatbelt, M R. Howell
Gypsum Use In The Wheatbelt, M R. Howell
Journal of the Department of Agriculture, Western Australia, Series 4
One of the limitations to crop productivity in the wheatbelt is the poor structure of heavy textured soils. Many years of clearing and cultivation have caused the loss of soil organic matter and breakdown of soil aggregates - particles of sand, silt and clay - in the surface layers. This has led to the development of unstable soils with poor physical properties.
Although loss of soil structure is a serious problem, it can be reversed by altering the tillage practices that caused the problem. This improvement in soil structure and return to productivity can be a slow process. However gypsum …
Increasing Groundwater Salinity In The Northern Wheatbelt, R J. Mcgowan
Increasing Groundwater Salinity In The Northern Wheatbelt, R J. Mcgowan
Journal of the Department of Agriculture, Western Australia, Series 4
Every farmer in western Australia's northern wheatbelt will know of a groundwater supply, be it bore, well or soak. that has become increasingly saline. The groundwater may have become more saline over a period of 15 years or more, or have been noticed only recently. Inevitably, the bore will lie within an area cleared for agriculture. This increase in groundwater salinity may be associated with soil salinisation. Although researchers have some understanding of the processes causing salinisation of groundwater in the wheatbelt and the extent of the problem, little is known about the rates of salinisation and groundwater rise. A …
Salinity Control In Northern China, G A. Robertson
Salinity Control In Northern China, G A. Robertson
Journal of the Department of Agriculture, Western Australia, Series 4
China has vast areas of saline land, perhaps as much as six million hectares. Some of this saline land is a result of marine influence in coastal areas and some is the resultof soil formation in areas with saline geological deposits and inadequate rainfall to leach out the salts at that time.
However, most saline soils in China are as a result of secondary salinisation processess induced by a hydrological imbalance resulting from over-clearing of the land or irrigation. This imbalance has produced rising watertables bringing the salt closer to the soil surface.
In this article, G..A. Robertson, Commissioner …
Northern Wheatbelt Water Supply Study, I A F Laing, R. M. Pridham
Northern Wheatbelt Water Supply Study, I A F Laing, R. M. Pridham
Journal of the Department of Agriculture, Western Australia, Series 4
Department of Agriculture surveys have shown that many farms in Western australia's northern wheatbelt have inadequate water supplies. More than 80 per cent of all farms in that area depend soley on groundwater for watering livestock, a much higher percentage than for most other farming areas. Because groundwater salinities have increased in recent years, concern is held for the long-term future of this recource.
In contrast to more southern agricultural areas, farm dams in the northern wheatbelt are relatively uncommon. Only 30 per cent of the existing dams in the northern wheatbelt constitute effective water supplies. More than half of …
Sandplain Hardpan : A Different Dam Construction Material, A F. Mccrea
Sandplain Hardpan : A Different Dam Construction Material, A F. Mccrea
Journal of the Department of Agriculture, Western Australia, Series 4
Before 1980, the Department of Agriculture did not believe that suitable farm dam materials could be found in light land soils. However Beacon earthmoving contractor, V> J> Pavlinovich, has demonstrated that where suitable cemented subsoils or 'hardpan' existed, a succcessful dam site could be found.
This material should not be confused with compaction or traffic hardpans ehich are dense layers of soil found near the surface. Traffic hardpans result from compaction of soil materials with the passage of vehicles and farm machinery. Rather, the hardpan referred to here is a natural subsoil layer that has been cemented by silica and …
Drought Proofing The Farm : Case Studies, J L. Frith
Drought Proofing The Farm : Case Studies, J L. Frith
Journal of the Department of Agriculture, Western Australia, Series 4
For many years, Western Australia's north-eastern wheatbelthas suffered chronic shortages of water for stock and domestic use. The area's averageannual rainfall is generally low - less than 300 millimetres - and droughts in the 1970s caused futher problems. manydams in the area leak or have inadequate catchmentsand groundwater is scarce ormofmpoor quality.
In March 982, the Western Australian Government provided $100 000 for the Department of agriculture to demonstrate the potential of establishing permanent, drought-proof water supplies on farms in the north-eastern wheatbelt. The methods were to use exixting techniques to build dams and catchments. In a year of low …

The Causes Of Saltland : A Case Study At Esperance, P R. George, S. C. Bull
Journal of the Department of Agriculture, Western Australia, Series 4
A series of bores on the Esperance Downs Research Station has demonstrated that the groundwater levels change after clearing, and the relatiojnnship between groundwater levels and soil salinity has been emphasised. This pattern of hydrological change leading to soil salinity problems applies widely in the wheatbelt.

The Comprehensive Water Supply Scheme, K J. Kelsall
Journal of the Department of Agriculture, Western Australia, Series 4
The Comprehensive Water Supply Scheme has been a great boon to the agricultural area, and it has received strong support from all political parties. The Scheme has been responsible for increased prosperity of country towns, the decentralisation of industry, and general improvements in the standard of living.
This is a look at the development of the Scheme.
P.W.D. Supplementary Public Water Supply Schemes, J E. Davis
P.W.D. Supplementary Public Water Supply Schemes, J E. Davis
Journal of the Department of Agriculture, Western Australia, Series 4
Shallow wells and soaks with very limited yields were the principal water sources for the early settlers.
Hundreds of such wells were constructed by the Public Works Department in remote areas.
In the early 1930s major development of water supplies from rock catchments was begun in the central wheatbelt.
After the war, larger and more effective earth moving equipment became available. The Public Works Department rehabilitated many old excavated dams as well as constructing new ones.
Roaded catchments were also developed during this post-war period. many farmers took advantage of Public Works Department technical advise and hired a P.W.D. grader …
Farm Dams In The Wheatbelt, I A F Laing
Farm Dams In The Wheatbelt, I A F Laing
Journal of the Department of Agriculture, Western Australia, Series 4
Of the estimated 76 000 farm dams in the wheatbelt, about 8 per cent either leak or are salt affected. The remaining 70 000 dams are capable of holding water for livestock use and can be regarded as sercicable dams.
A great many of the serviceable dams are unreliable water supplies due to the combined effects of lack of runoff from catchments, shallow depth of storage and small size of storage in relation to expected demand from livestock and evaporation loss.

Some Basics Of Marron Production, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
marron are native to the South-West of Western Australia, and are keenly sought by inland fisher-men. However, supplies do not equal the apparent demand.
One solution is to cultivate marron in farm dams, or more intensively as a commercial enterprise.
This article suggests a few guidelines for marron production.
