History Of The State Vermin Barrier Fences, Formerly Known As Rabbit Proof Fences, J S. Crawford Jan 1969

History Of The State Vermin Barrier Fences, Formerly Known As Rabbit Proof Fences, J S. Crawford

Research Reports

There is evidence of rabbits arriving in Australia as far back as 1788, and it is well known that others were liberated on islands around the coast, including some off the coast of Western Australia. However, they remained localised and it is now generally accepted that the rabbits which did spread originated from a small shipment of the wild type brought on the Clipper “Lightning” in 1859. They were released on “Barwon Park”, the property of Thomas Austin, near Geelong in Victoria, and within three years, had reached pest proportions


Ammonium Nitrate Vs Urea, M G. Mason Jan 1969

Ammonium Nitrate Vs Urea, M G. Mason

Experimental Summaries - Plant Research

Ammonium nitrate is a source of nitrogen containing half

its nitrogen in the ammonium form and half in the nitrate form.

Some properties are set out in comparison with urea in the

following table.

Ammonium nitrate has an advantage over urea in that it can

be topdressed onto the surface of the soil and left uncovered

without a danger of loss of nitrogen to the atmosphere. When urea

is left uncovered on the surface of the soil losses of nitrogen occur

through volatilisation of ammonia during the hydrolysis of the urea.

Such losses with ammonium nitrate are only likely to …


Honey Plants In Western Australia, F. G. Smith Jan 1969

Honey Plants In Western Australia, F. G. Smith

Bulletins - 3000 - 3999

Successful honey production depends, among other things on a good knowledge of the plants which produce nectar.

Every apiarist needs to know which plants are of importance to honey-bees, where those plants occur, and when they flower. He also needs to know which plants produce nectar which will result in the production of good quality honey, and which produce unpalatable or unmarketable honey. To maintain the strength of his bee colonies he also needs to know which plants produce nutritious pollen.

The object of this bulletin is to provide the basic information on these subjects in the main beekeeping areas …


Soil Conservation Land Use, J E. Watson Jan 1969

Soil Conservation Land Use, J E. Watson

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

MANY things are blamed for soil erosion—including storms, fires, cost-price squeezes, ploughing downhill and rabbits. But the basic factor is the risk involved in the way the land is used.

It is therefore vital that everyone—not only farmers—should begin their thinking about soil conservation from the land use aspect (of which special practices such as contouring, are a small though spectacular part.)


West Midlands Development : Erosion Prevention And Control, G W. Spencer Jan 1968

West Midlands Development : Erosion Prevention And Control, G W. Spencer

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

THE prevention of soil erosion is essentially a matter of using each soil according to its potential, and treating it according to its needs.

Good land use and sound management practices are the best preventive measures.

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

Most clearing in the West Midlands is carried out by chaining, though the method chosen will depend on the country being cleared and on the resources of the farmer.


West Midlands Development : Fertilizers For The West Midlands, Department Of Agriculture, Western Australia Jan 1968

West Midlands Development : Fertilizers For The West Midlands, Department Of Agriculture, Western Australia

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

FARMING the light lands of the West Midland area would be impossible without fertilisers.

Most light land areas are inherently very low in phosphate and also require nitrogen.

The nitrogen can come from fertiliser for cereal crops, or can be built up by growing appropriate legume pasture plants such as clovers and lupins.


West Midlands Development : Cereals For The West Midlands, Department Of Agriculture, Western Australia Jan 1968

West Midlands Development : Cereals For The West Midlands, Department Of Agriculture, Western Australia

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

THE sandplain soils and climate of the West Midlands area are primarily suited to grazing.

However, the place of cereals is receiving a great deal of attention in view of their advantages in the early stages of development, and the need for the diversification of farm production.


Wheat In Development Programmes For New Esperance Farmers, R J. Doyle, G. D. Oliver Jan 1968

Wheat In Development Programmes For New Esperance Farmers, R J. Doyle, G. D. Oliver

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

IN the December, 1967, issue of the Journal of Agriculture, we reported on five development budgets for the Esperance region.

The aim of the exercise was to find out if a new settler concentrating on sheep, with $20,000 available for development after acquisition of land, could make a reasonable living for himself and his family while developing his farm.


Multiple Cropping Will Increase The Erosion Hazard, W J. Burdass Jan 1968

Multiple Cropping Will Increase The Erosion Hazard, W J. Burdass

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

WITH the low price of wool and the price of wheat high in comparison, farmers need little encouragement to increase their acreage of crops.

Unfortunately with increased cropping comes the risk of increased erosion—unless there is a simultaneous increase in the use of conservation practices.


Private Irrigation Systems : Do They Pay?, G D. Oliver Jan 1968

Private Irrigation Systems : Do They Pay?, G D. Oliver

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

WESTERN AUSTRALIA, with 71,000 acres under irrigation, can hardly claim to have an important irrigation farming industry.

However, irrigation is daily growing in importance, especially through private schemes. These account for almost half the present irrigated area.

West Midlands Development : Pastures For Sandplain Soils, Department Of Agriculture, Western Australia

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

TRIALS at the Badgingarra Research Station have indicated that many pasture species will grow in the West Midlands area.

Choice of the species most suited to any particular locality will be influenced by soil type, rainfall, grazing characteristics and possible ill-effects on stock.

The following species have been recommended.


The Phosphorus Fertilisers : How They Compare, Walter Jacob Cox Jan 1968

The Phosphorus Fertilisers : How They Compare, Walter Jacob Cox

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

ALTHOUGH 'double' or 'concentrated' superphosphate was first commercially manufactured in 1872 it was not until the 1950's that it became a major commercial fertiliser. In 1965 it accounted for about 15 per cent, of the world production of phosphatic fertilisers.


The Function And Use Of Sulphur Dioxide In West Australian Winemaking, D Mann Jan 1968

The Function And Use Of Sulphur Dioxide In West Australian Winemaking, D Mann

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

THE judicious use of sulphur dioxide is perhaps the most important of the fundamentals of winemaking in a hot climate.

Western Australia's vintage, centred in the Swan Valley just a few miles north-east of Perth, is subjected to some of the highest summer temperatures experienced by a quality wine producing district.

In this environment, it is important to make good use of sulphur dioxide to avoid wine spoilage.


The Ord River Regeneration Project. 2. Dealing With The Problem, K Fitzgerald Jan 1968

The Ord River Regeneration Project. 2. Dealing With The Problem, K Fitzgerald

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

THE PROGRAMME of protective and remedial work being undertaken in the Ord River catchment area had as its major objective the re-establishment of perennial vegetation, as a means of controlling erosion and reducing the silt load of the rivers. It is now in its seventh year of operation.


The Ord River Regeneration Project. 3. Eight Years Of Progress, K Fitzgerald Jan 1968

The Ord River Regeneration Project. 3. Eight Years Of Progress, K Fitzgerald

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

REGENERATION of degraded areas in regions of marginal rainfall is a slow process under the best of conditions, but on the Ord River Catchment, where much top-soil had been removed, the problem was unusually severe.

In many areas top-soil will have to be rebuilt before vegetation can be re-established.

This will be a long, slow process and regeneration will proceed through gradual plant succession from the "pioneer" annual species through to the permanent and more productive perennial species needed for a stable catchment area.

West Midlands Development : Water Supplies In The West Midlands, I A F Laing

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

IF it is practical and economic to develop both surface and underground supplies, the aim on each farm should be to provide half the farm water requirement from dams, and the other half from bores.


The Effects Of Shearing Time And Stocking Rate On Wool Production, R J. Lightfoot Jan 1967

The Effects Of Shearing Time And Stocking Rate On Wool Production, R J. Lightfoot

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

THE results of the first experiment comparing "autumn" versus "spring" shearing over a two-year period were published in 1960.

In this experiment the autumn-shorn ewes cut heavier greasy fleeces (even though they also reared considerably more lambs) with less tender wool, resulting in a higher average return per head from this group.

The autumn-shorn wool carried more seed, was less attractive and contained relatively more pieces than did the spring-shorn wool.


Pumping And Horsepower, R P. Harington Jan 1967

Pumping And Horsepower, R P. Harington

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

WATER is vital to the survival of plants and animals and its availability will influence the site of the homestead and the farm layout generally.

This article describes some of the factors involved in the installation of a pumping outfit for domestic and stock requirements.
