Modifying Fertiliser Practices, J S. Yeates, D. M. Deeley, M. F. Clarke, D. Allen Jan 1984

Modifying Fertiliser Practices, J S. Yeates, D. M. Deeley, M. F. Clarke, D. Allen

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

If modified fertiliser practices are adopted phosphorus losses from the Peel-Harvey catchment can be reduced. Farmers can save money on fertiliser applications and the need for more expensive catchment management measures to reduce algal pollution of the estuary will be avoided.

Research data available so far indicate that, with farmer co-operation and the use of the new slow release fertiliser New Coastal Superphosphate, long-term phosphorus application rates can be reduced by 30-40 per cent - and possibly even halved - without lowering agricultural production. This will also reduce phosphorus loss to drainage water.

Although much of the research since 1982 …


Tackling The Problem Off The Farm, C M. Croft Jan 1984

Tackling The Problem Off The Farm, C M. Croft

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

Methods of redusing phosphorus losses from the catchment soils of the Peel-Harvey esturine system have been discussed in other articles in this Journal.

This article briefly discusses a range of 'off the farm' techniques to improve phosphorus flushing from Peel Inlet or Harvey Estuary to the sea and to treat the phosphorus and the algae. These techniques were among more than 100 management options evaluated by the Peel-Harvey Study Group.

Summary Of Rhizobium Experiments, J G. Howieson Jan 1984

Summary Of Rhizobium Experiments, J G. Howieson

Experimental Summaries - Plant Research

The main emphasis for rhizobial work in 1984 was on the acid tolerance of medic Rhizobium. The experimental programme in the field was greatly expanded to include testing of some 160 isolates collected from Sardinia in May 1984. Broadacre sowings of acid tolerant strain WSM 419 were undertaken as a preliminary step to its commercial release in 1985. Glasshouse work in 1984 was dedicated to a more intensive investigation of the factors contributing to the enhanced nodulating ability of M. polymorpha and M. murex on acid soils. As well, a simple technique for identifying acid tolerant strains of rhizobia in …

Skeleton Weed : How Serious A Threat In Western Australia?, F D. Panetta, J. Dodd Jan 1984

Skeleton Weed : How Serious A Threat In Western Australia?, F D. Panetta, J. Dodd

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

Skeleton weed is probably the most serious weed ever to threaten the Australian wheat industry. It interferes with wheat cropping at two stages: through competition with the growing crop, particularly for nitrogen and water during the crop's development: and later through the production of a tall, wiry flowering stem which tangles in harvesting machinery and can make harvesting difficult, if not impossible.

The weed is a major problem in eastern Australia although a combination of cultural, chemical and biological control programmes is helping to reduce its impact.

In Western Australia, skeleton weed is being contained mainly by eradication efforts. Weed …

Keeping Starlings Out Of W.A, John L. Long Jan 1984

Keeping Starlings Out Of W.A, John L. Long

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

In Europe and North America huge flocks of starlings cause millions of dollars worth of damage to grain and fruit crops each year and large sums of money are spent trying to control them.

Starlings were introduced into australia in the late 1890s when more than 200 birds were released near Melbourne. They are now well established over much of eastern Australia, ranging from central Queensland, south to Tasmania and along the Great Australian Bight to the South Australian-Western Australian border, occasionally crossing it and sometimes moving as far west as the Esperance region on the south coast.

New Grape Varieties For Premium Wines, A C. Devitt Jan 1984

New Grape Varieties For Premium Wines, A C. Devitt

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

The quantity and style of wine consumed in Australia has changed dramatically since the 960s.

Besides the increase in consumption from 9 to 19.9 litres per head in the past 10 years, the major changes have been the greater importance of table wine, particularily white table wine, and the more exacting standards set by consumers and wine producers.

Also more importance has been placed on distinctive regional and varietal wines and the role of premium varieties.


Algal Growth And The Phosphorus Cycle, Arthur J. Mccomb, K. S. Hamel, A. L. Huber, D. K. Kidby, R. J. Lukatelich Jan 1984

Algal Growth And The Phosphorus Cycle, Arthur J. Mccomb, K. S. Hamel, A. L. Huber, D. K. Kidby, R. J. Lukatelich

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

Larger algae and microscopic phytoplankton foul the waters of the Peel-Harvey estuarine system, upsetting the fishery and polluting the beaches.

These aquatic plants grow in response to phosphorus runoff from drainage, trapping phosphorus in the estuary and using it in their growth. When they die this phosphorus remains in the system to be recycled for further plant growth.

Algal pollution in the estuary can be lessened by reducing the amount of phosphorus entering the system, increasing phosphorus losses to the ocean, or in some way blocking the trapping and recycling processes.


The Stripe Rust Threat, B R. Whan, T. N. Khan Jan 1984

The Stripe Rust Threat, B R. Whan, T. N. Khan

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

The wheat disease stripe rust caused crop losses estimated at $20 million in New South Wales during an epidemis in 983. Economic crop losses were reported in neighbouring States and as far westas Ceduna in South Australia. In some States large areas were sprayed with fungacide at considerable cost to control disease spread.

Wheat stripe rust has not been found in Western Australia yet, but all current evidence indicates that it will eventually reach this State.When it does, it has the potential to cause considerable crop losses every year, unlike the spasmodic losses from stem rust, and it will greatly …


Soil Acidity In The Eastern Wheatbelt, W M. Porter, I. R. Wilson Jan 1984

Soil Acidity In The Eastern Wheatbelt, W M. Porter, I. R. Wilson

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

In Western Australia parts of the sandplain of the eastern wheatbelt are very acid and produce poor crops, It was not until the late 1970s that the effect of soil acidity on the productivity of the sandplain soils was examined in any detail.

Since then researchers have learnt a great deal about the nature of soil acidity in the eastern wheatbelt sandplain soils and can suggest management options for farmers.

This article discisses the problem of the very acid soils. It does not deal with the moderately acid, medium textured soils of the eastern wheatbelt. Although the acidity of these …

Naturalised Subterranean Clover Strains Of Western Australia, W J. Collins, John S. Gladstones

Technical Bulletins

A description is given of the characteristics and distributions of 115 distinct naturalized strains of subterranean clover. Approximately three-quarters of the strains appeared from their distributions to have been introduced and to have spread in their present forms, while the remainder, which are individually of very limited distribution, appeared to have evolved locally from naturalized and commercial material by natural crossing of mutation. An attempt was made to relate the apparent ecological succes rial, and a high level of hard-seedeness.
