Soil Conservation Earthworks Design Manual, K J. Bligh

All other publications

In view of the great diversity of hydrological conditions encountered in the field, and the relative paucity of information with which to design soil conservation earthworks, it is frequently not possible to quantify all aspects of hydrologic design. It remains for the practising soil conservationist to search for a reasonable solution to a problem which is most appropriate to the situation, location, information and skills. The equations in this Manual provide the best available estimates of flow rates and volumes for carrying out design but it must be recognised that the information has come from a relatively limited data set, …

Artificial Insemination Of Ewes With Fresh Semen, Jonathon Hunton, Keith Kroker

Bulletins 4000 -

This Bulletin gives a basic outline of the technique for artificial insemination (Al) of sheep. The topic is large and incorporates several areas of reproductive physiology which can only be given cursory treatment in this publication. Much of the information discussed is also applicable to goat breeders wishing to use AT, although there are some fundamental differences.

The Commercial Production Of Musk Melons, Neil Delroy, Harry Gratte

Bulletins 4000 -

This research publication covers commercial production of musk melons, Cucumis melo L., that belong to the cucurbit family. The must melon group includes rock melons (cantaloupes), honey dew melons, Japanese musk melons, hami melons and a number of other types of musk melon.

Finishing Kimberley Cattle In The South-West, Brian L. Mcintyre, Bill Ryan, Neville Macintyre

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

The idea of integrating the Kimberley cattle industry with that in the south-west of Western Australia is no new, but until recently it had not been critically evaluated.

Over the past eight years the Department of Agriculture's Beef Cattle Branch has been assessing the performance of Kimberley cattle transported south for finishing in the agricultural areas.

This research has show that Kimberley weaners can be finished in the south, and that under the present (December 1988) economic conditions it is more profitable than running breeding cattle in the south-west and comparable with fattening store steers.

Economic Impact Of Growing Phomopsis-Resistant Lupins, J M. Warren, Jeremy Allen, Wallace Cowling

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

The planting of Phomopsis-resistant lupins will increase net farm income. They will also alter the traditional blend of pastures and cropping, depending on grain and wool prices. In mixed farming areas of Western Australia's southern wheatbelt, they will allow more land to be sown to lupins rather than cereals on farms in which the lack of sheep feed over summer severely restricts wool production.

The benefits of Phompsis-resistant lupins arise from a reduction in sheep deaths due to lupinosis, a longer safe grazing period (free from lupinosis) on lupin stubbles, a decrease in the need for supplementary sheep feed over …

The Effect On Farm Profit Of Conserving Stubble To Prevent Wind Erosion, A D. Bathgate

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

Over-grazing of stubbles is a major cause of winf erosion on WesternAustralian farms. Stubble contributes to the 'roughness' of the paddock; as the roughness is reduced, the risk of winf erosion is increased.

The risk of lupinosis in sheep has previously reduced the likelihood of lupin stubble being over grazed, but the development of Gungurru, a phomopsis-resistent variety of lupin, has increased the potential for over-grazing and hence the probability of wind erosion.

This article describes the economic benefit (or cost) of conserving stubble at the conservation standards.

Prospects For Leucaena On The Ord, D Pratchett, Tim Triglone

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

For the past few years, the Department of Agriculture has been fattening cattle on the forage shrub leucaena which is grown under irrigation with pangola grass. About 400ha of leucaena is under commercial production in the Kimberley.

Cattle grazing leucaena show promising growth rates but other problems need to be overcome before its use is more widely adopted. Leucaena establishes slowly. It is also costly to transport fattened cattle to southern abbatoirs.

Weighing Scales For Sheep Do Pay, W D. Roberts

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

Sheep producers can improve production by using weighing scales and keeping accurate records of weights.

Withiut some objective measurement, such as weighing, producers have no accurate method of identifying the heaviest, lightest and average weight of a group of sheep.

They could try to esstimate weight by eye - but most people are poor judges of body weight.

East Ballidu Catchment Report, L K. Lenane, C Henschke, C Thorne, D Kessell

All other publications

It will require the total cooperation of all members of the Soil Conservation District to remedy the area's problems. The first priority is for the control and better use of water on the recharge areas. The wheat/wheat/lupin rotation at present offers the best economic option. Lupins are well suited to the areas of lighter land. If lupins are planted on waterlogged soils or otherwise unsuitable soils, problems will arise and perhaps prejudice their use on the widespread suitable areas. The use of trees below rocky outcrops is an important measure to prevent excessive recharge of the deeper aquifers. Where trees …

Trees In The Peel-Harvey Catchment, C S. Peek, Richard Silberstein

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

The peel-Harvey catchment has been the focus for an intensive research and extension programme to reduce phosphorous run-off flowing into the Peel Inlet and Harvey Estuary, while maintaining agricultural productivity.

One of the proposed management strategies is to plant large areas of trees on the catchment's leaching sands. Farmers would be encouraged to take this option if growing trees was at least equal, in financial return, to the present agricultural land uses.

Preliminary data indicate that growing Eucalyptus globulas (Tasmanian bluegum) for woodchipping may be at least as profitable as agriculture. Tree plantations also have the added potential to reduce …
