Weed Control In Cereals : Aerial Spraying Trials, G R W Meadly

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

SPRAYING cereal crops for weed control is now standard farming practice in Western Australia. Almost 500,000 acres of cereal crops, mainly wheat, are sprayed each year, and approximately three-quarters of this area is treated by aircraft.

Recent trials have shown that aerial application of 'extra low" volumes of hormone-like herbicides, with oil or water solvents, does not damage cereals if spraying is done at the right stage of growth.

Local Control Of Crows By Trapping, C J. Woodbury

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

THE common crow seen frequently around farms in the South-West is the raven (Corvus coronoides) whilst the pest of pastoral areas is the true Australian crow (Corvus cecilae).

Farmers and pastoralists, although recognising the importance of these birds as scavengers and destroyers of insects, particularly grasshoppers, sometimes for one reason or another, wish to reduce their numbers over a localised area.

Baiting with phosphorus has been used in the past, but the purpose of this article is to describe and illustrate a type of trap which has become universally known as the "Australian Crow Trap."

Water Conservation On The Farm, John W. Lewis

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

SMALL scale conservation of water for agricultural use is becoming increasingly important throughout Australia.

As land development intensifies, it is natural that farmers turn to more dams and earthen tanks for stock water and irrigation.

Adequate water is essential to supply the carrying capacities made possible by improved pastures, and where greater quantities of water can be stored, fodder crops, pastures, orchards and vegetables can be irrigated.

A Crush For Tuberculin Testing Of Cattle, A L. Ripper

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

ALWAYS a useful asset on any farm where livestock are kept, a strongly-constructed crush is essential where tuberculin testing makes it necessary to deal with dry stock, bulls and young animals that have not been previously handled.

The crush described in this article was specially designed for tuberculin testing, but will serve equally well for vaccinating, branding, de-horning or any operation where restraint is necessary.

Australian Tractor Tests : Fordson Farm Major : Report On Test No. 33, G H. Vasey, W. F. Baillie

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

THIS Report is taken from the full Technical Report No. 33 of this test; test results are shown here in briefer form: fuller explanations are added.

Values quoted may be rounded out to two instead of three significant figures; to this extent the values may differ slightly but not significantly from those shown in the Technical Report.

Graphs of belt test performance, shown in the Technical Report, are not shown here.

Potatoes Sprinkler Irrigated From The Collie River, John W. Lewis

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

THE highly productive soils of the flats along the Collie River at Roelands are an important source of many of our summer grown potatoes in this State.

Large areas are planted year after year, the record being held by Mr. Clarry Cox of Roelands, who has planted potatoes on the same seven acres every season since 1922.

Blasting. Part 2. Explosives On The Farm, G A. Greaves

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

EXPLOSIVES will function with maximum reliability and efficiency only when they are carefully stored under cool, dry conditions so as to avoid deterioration.

When preparing charges the user should follow a correct procedure and use the proper tools. Always treat explosives with respect and remember they are made to explode. When they hit they hit hard.

Getting The Best From Your Sewing Machine, O. Evans Scott

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

"NEXT to the plough, this is perhaps humanity's most blessed instrument." (Louis Antoine Godey.)

In some homes the sewing machine is the most sadly neglected and ill-used servant. It is often left set up, exposed to dust, dampness and scratching, used as a table and otherwise abused.

It is not right to have a machine stitching imperfectly and noisily and used for long periods without maintenance when a little attention can keep it performing quietly and efficiently.

Australian Spark Arrester Tests : Test No. Spa-21 : Caterpillar D7 Turbocharger, W F. Baillie, G. H. Vasey

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

FORMAL tests on spark arresters are conducted by The Tractor Testing Committee* at the Testing Station, Werribee, on behalf of those Companies concerned with tractors, engines or spark arresters who wish to have these equipments tested.

The arrester is tested on the engine it is specially designed for (as in this instance), or if it is sold for use on any or several engines, it is tested on an engine of the highest power for which the spark arrester is intended.

Flooding Of Salt Land, C V. Malcolm

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

Many farmers have expressed concern and some have gone to considerable expense in trying to alleviate flooding problems on salt affected land.

Some consideration will be given here to flooding, its causes, effects on salt encroachment, methods of prevention and alleviation.

Automatic Waterers For Day Old Chickens, P Smetana, W. Ward

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

ONE of the most tedious and time consuming tasks on a poultry farm is the provision of water to chicks from day old up to the age of three or four weeks.

Most poultry farmers use half-gallon glass fonts with metal bases for the first few weeks, until the chicks are old enough to use the automatic watering system usually situated along one wall of the brooder house.

This cumbersome glass font system can be replaced by the cheap and easily installed automatic watering system described below. This system has already been adopted by several local poultry farmers.

Plan For Quality In Silage, Department Of Agriculture, Western Australia

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

SILAGE making time is fast approaching in the South-West.

Last minute preparations before harvesting will help avoid delays at the time of making this valuable fodder, thereby reducing the amount of costly spoilage caused by hold-ups.

Blasting. Part 1. Explosives And The Farmer, G A. Greaves

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

ABOUT 3,000 tons of commercial blasting explosives of various types are used every year in Western Australia of which approximately two thirds is utilised by mining industries and the remainder goes mainly to quarrying and public works.

The farmer and orchardist actually use only very small amounts but nevertheless explosives are a very useful working tool for the primary producer.

A New Type Of Seed Bed Cover For The Market Garden, R R. Bell, M. Hardie

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

ALL market gardeners use seed beds in their gardening programme. However, the basic design of seed beds and covers has not greatly altered over the years.

The availability of cheap good quality plastic materials has now shown the way to improvements in the design of this type of gardening equipment.

Let's Look At Herringbone Dairies, R A. Bettenay, F. Fielder

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

THE first of the modern type herringbone dairies in Western Australia was constructed by Mr. F. Tucker of Ruabon, in 1957.

Since then there has been strong interest in this system, and there are now at least six such sheds operating in the district between Ludlow and Augusta. Many more are being constructed.
