Wildflowers Of The Stirling Range, Alexander S. George Jan 1969

Wildflowers Of The Stirling Range, Alexander S. George

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

TWO hundred miles south-east of Perth, the Stirling Range rises abruptly from the surrounding plain. About forty miles long, it is a line of semi-isolated hills, rather than a continuous block.

There are many intriguing plants of diverse colour and form. Well over 400 species are known from the Range. A number of these are found no-where else, and some are restricted to one mountain.


Pastures For The Pastoral Areas, D G. Wilcox, K. Fitzgerald Jan 1969

Pastures For The Pastoral Areas, D G. Wilcox, K. Fitzgerald

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

The pastoral areas lie generally outside the zone where cultivated crops are grown.

The rainfall is erratic and the basic pastures for sheep and cattle consist of native plants.

In some favoured areas however, and in particular situations, sown pasture species are becoming increasingly important.

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 …

Soil And Tissue Testing For Potassium., Department Of Agriculture And Food, Western Australia Jan 1969

Soil And Tissue Testing For Potassium., Department Of Agriculture And Food, Western Australia

Experimental Summaries - Plant Research

No meaningful conclusions can be drawn until the multiple regression analysis comparing soil and plant parameters with level of response has been completed. Similarly it is extremely dangerious to extrapolate results obtained from any one experiement in a particular district to the general farm situation. In addition these results represent only 1 rather atypical season and so need to be verified by additional calibration trials. in 1973 (40) and 1974 (20).

Time Of Application Of Solid Nitrogen Fertilisers., M G. Mason

Experimental Summaries - Plant Research

The current recommendations for time of application of soild nitrogen fertilisers such as urea, ammonium nitrate and sulphate of ammonia are:

Zone A: These fertilisers should be applied as close to seeding as possible.

Zone B: As for zone A except on very sandy soils which are very prone to leaching, where application can be delayed 2-3 weeks.

Zone C: Applications should be delayed about 3 weeks after seeding.

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

Nitrogen Use On First Crops After Legume Pasture, M G. Mason

Experimental Summaries - Plant Research

Apart from the normal factors affecting response of cereals to nitrogen fertilizers, i.e. length of growing season, rainfall, soil type etc, there are other factors which affect the response after a legume pasture. these factors include length of the previous legume phase and how good was the stand of legumes. Unfortunately for most of the trials in the past, involving the use of nitrogen on first crops after legumes, this information is not available.

Bulletin No 3609 - Land Development In The South Eastern Wheatbelt, G T. Halpin, P. Nelson Oct 1968

Bulletin No 3609 - Land Development In The South Eastern Wheatbelt, G T. Halpin, P. Nelson

Bulletins - 3000 - 3999

Interest in the development of light lands in the south-eastern wheatbelt was spurred by the many ex-servicemen seeking farms after the 1939-45 World War.

Previous attempts to develop this area had been frustrated by poor crop yields, and by the poor carrying capacity of those volunteer pastures which developed on cleared land.

Research into reasons for the poor crop results was begun in 1948-49 with trials sown by Messrs Smith and Halpin between Borden and Lake Grace. The results clearly showed the important role played by copper and zinc in successful crop growth. Since then, field trials have been conducted …

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.
