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.

Bulletin No 3547 - Kimberley Research Station - Progress Report 1968, Western Australian Department Of Agriculture

Bulletins - 3000 - 3999

Rivers flowing to the Gulf of Carpentaria and the Timor Sea have been estimated by hydrologists to carry about three times the water transported annually over the Murray drainage system and the South Eastern slopes which, together, comprise the highly settled agricultural areas of South Eastern Australia.

In 1945, the North Australian Development Committee recommended research in the Ord-Victoria rivers region as a first step toward ultimate agricultural development of this Northern potential and, in 1946, the Kim- berley Research Station commenced operations under the joint control of the Commonwealth Scientific and Industrial Research Organization and the Western Australian Department …


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.

Fisheries Report No 3 - Western Australian Freshwater Fisheries, Donald D. Francois Jan 1966

Fisheries Report No 3 - Western Australian Freshwater Fisheries, Donald D. Francois

Fisheries Research Reports

Most of the Australian States have a comprehensive system of inland waterways, Western Australia, however, is in a less fortunate position. True, the maps of the State show many rivers, but in much of the southern, more populous part, with no summer rain and no winter snow, the majority are virtually a chain of waterholes during the long summer months. At the same time, in a relatively small section in the south-west corner, there is a series of permanent streams flowing through what was originally dense forest. But apart from the three indigenous freshwater crustaceans, the marron (Cherax tenuimanus), the …


Salinity And Farmhouse Water Supplies, T C. Stoneman Jan 1966

Salinity And Farmhouse Water Supplies, T C. Stoneman

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

PROVISION of a satisfactory water supply for the homestead is one of the many problems which have to be faced by all farmers.

For those served by the Comprehensive Water Supply Scheme, the solution is fairly simple.

For others, finding an adequate supply of good quality water can often be quite a headache.


Piggery Septic System, N E. Macintyre Jan 1966

Piggery Septic System, N E. Macintyre

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

ONE of the problems of intensive houses for pigs is the disposal of the dung and urine.

If proper arrangements are not made to remove this, it soon accumulates in an offensive pile at one end of the piggery, making an excellent breeding ground for flies.


Egg Shell Quality, R J. Bishop Jan 1966

Egg Shell Quality, R J. Bishop

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

Recent overseas work and local industry developments indicate that the calcium content of feed for laying hens in Western Australia should be increased to achieve satisfactory egg shell strength.

Summer And Autumn Rainfall In Relation To Epidemics Of Wheat Stem Rust In Western Australia, W A. Shipton

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

High summer and autumn rainfalls, followed by rust infection of volunteer plants and favourable conditions during late winter and spring, lead to rust epidemics.

WIDESPREAD outbreaks of wheat stem rust are rare in Western Australia.


Cultivation : Does Haste Mean Waste?, H M. Fisher Jan 1966

Cultivation : Does Haste Mean Waste?, H M. Fisher

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

Many farmers believe that increasing the speed of cultivation and seeding implements will cause deterioration of soils and reduced crop yields.

In a three-year trial on clover ley land at Wongan Hills higher cultivation speeds tended to increase rather than decrease wheat yields. There was some deterioration in the physical structure of the soil.

A History Of The War Service Land Settlement Scheme Western Australia, A, R. Barrett Jan 1965

A History Of The War Service Land Settlement Scheme Western Australia, A, R. Barrett

Farm Systems and Economics published reports

In writing a history of the Western Australian War Service Land Settlement Scheme, it is pertinent to remark that land settlement projects have ever been difficult and, in fact, to date very few have been really successful. However, there has always been the necessity to accede to the desire of returning men to go on the land, also in States such as Western Australia there was and still is the need for further land development. Therefore, when the Commonwealth Government offered to provide the funds for servicemen's rehabilitation on the land the State gladly accepted and agreed to take responsibility …

Seed And Pasture Rates For New Dairy Pastures, F E. Ryan Jan 1965

Seed And Pasture Rates For New Dairy Pastures, F E. Ryan

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

THE success or failure of pasture establishment on new land often depends on the interaction of rate of seeding and rate of superphosphate application.

Every year large areas of virgin land are cleared and sown to pasture in the higher rainfall areas, and all-too often the new pasture is not as successful as it should be because too little super is applied, and, in some cases, too little seed.


Lot Feeding Of Beef Cattle. 3. Facilities Required For A Feed Lot, W J O Wilkie Jan 1965

Lot Feeding Of Beef Cattle. 3. Facilities Required For A Feed Lot, W J O Wilkie

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

MANY THINGS must be considered in planning a feed lot.

The site must be well chosen, fencing, gates and yards must be adequate for the cattle carried and feeding and watering facilities should be of a high standard.

Other things to consider are the provision of shelter and shade for the cattle and buildings for feed storage and other purposes.

Although the protein content of West Australian f.a.q. wheat averages only 9.4 per cent., often substantial amounts of comparatively high protein wheat are contained in this mixture.

However the quantity varies widely from year to year and is obtained from widely scattered areas of the wheatbelt.


Fisheries Report No I (1) - The Shark Bay Fishery On Snapper Chrysophrys Unicolor (Quoy And Gaimard), B. K. Bowen Jan 1964

Fisheries Report No I (1) - The Shark Bay Fishery On Snapper Chrysophrys Unicolor (Quoy And Gaimard), B. K. Bowen

Fisheries Research Reports

As regards both catch and value, the Shark Bay snapper fishery is the second most important scale fishery in Western Australia. Until 195%, the fishing was done solely by means of hard-lines operated from beats drifting over the snapper patches. In 1959 traps were first used with great success and in 196) this method of fishing was again the principal technique.

Prior to the 1960 season there were several suggestions that the use of traps would have a deleterious effect on the fishery. On October 19, 1959, the Western Australian League of the Professional Fishermen's Association wrote to the Fisheries …

Grade Herd Recording, 1963-64, Maurice C. Cullity Jan 1964

Grade Herd Recording, 1963-64, Maurice C. Cullity

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

A review of Grade Herd Recording during the 1963-64 season.

THERE was a substantial increase in the number of cows which were recorded in 1963-64 compared with 1962-63 (23,520 and 22,635 respectively).

This season's figure represents 20.4 per cent, of all cows in the dairying districts.

The number of cows which completed lactation and therefore whose yields were included in the averages, rose from 17,258 to 19,011.
