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

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).

Fertility Build-Up In Wheatbelt Soils, M D. Carroll

Experimental Summaries - Plant Research

Areas of loamy sand from Wongan Hills Research Station, which had carried subterranean clover for varying numbers of years, were sampled at five depth intervals to 60 cm. Wheat yield and a range of soil properties were related to numbers of years under subterranean clover. (W56H)

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

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

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 …

The New Course At Muresk Agricultural College, D K. Bartels

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

THE original aim of all the agricultural colleges in Australia was to train young men to be farmers.

Over the years, and particularly in recent years, the colleges in the Eastern States found that less and less of their students were coming from the farming community, and a diminishing number were returning to farming.

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.

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.

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.

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

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

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.
