Control Of Water Resources In W.A, T C. Calder

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

Use of underground and surface water is controlled so that the supplies are available to the general benefit of all domestic, industrial and agricultural users in a particular area.

Water is a valuable resource and its contamination and wastage must be avoided. This article outlines the provisions of the Rights in Water Act which is designed to protect water supplies from undue exploitation, contamination and wastage.

Linseed Within The Clover Ley Farming System, Department Of Agriculture, Western Australia

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

LINSEED was one of the first crops to be widely used as an alternative to cereals in the over-17 inch rainfall areas. It is now an established crop with a total 1969 production worth just under half a million dollars.

Linseed is currently worth nearly twice as much as wheat per bushel, wih its short term prospects still attractive.

Progress In Research On Noxious Weeds, Geoffrey A. Pearce

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

RESEARCH on noxious weeds has enabled the development of many practical methods for the control of these weeds.

Where the recommended treatments have been accepted by farmers, large scale operations have reduced the areas infested and stopped spread into new paddocks.

Establishing Pastures Under Wheat Crops, M L. Poole, J. W. Gartrell, D. A. N. Nicholas

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

In the drier wheatbelt areas the figure is 20 to 30 per cent.

Nitrogen Fertiliser Survey, Department Of Agriculture, Western Australia

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

THE DECEMBER, 1968 issue of the "Journal of Agriculture" included, as part of an article on the economics of nitrogen fertiliser use, a lift-out section for farmers to complete and return to the Journal.

Wildflowers Of The Geraldton District, E M. Bennett

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

THE wildflowers of Western Australia which have aroused such interest throughout the world are found largely in the south western corner of the State.

Within this area, and indeed in the drier areas also, certain districts are richer than others.

One example of this concentration of wildflowers occurs to the north and east of Geraldton.

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.

GRASSHOPPERS and locusts are among the most ancient enemies of the farmer, for they figured prominently in Biblical times, and periodically throughout the ages have devastated crops in all parts of the world.

Control Of Weeds In Garden Areas, Geoffrey A. Pearce

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

THE present-day gardener does not appear to relish the tedious job of removing weeds by hand. It is a never-ending task and no sooner is one germination controlled than another appears.

Modern herbicides provide a ready answer for overcoming the weed problem in the home garden, but it is essential to select the correct chemical and to understand its limitations.

The Indian Crow, John L. Long

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

Ornamental Trees For The Farm Garden, P Luff

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

THE need for trees in the farm garden is being realized by many people.

Trees around the homestead are required to give such features as shade, colour, fragrance and many other advantages to generally make an area more livable.

Besides these advantages, trees appear to help smaller plants flourish by increasing the humidity and providing various degrees of shade and sunlight.

Weaning Lambs Under Pastoral Conditions, H Suijdendorp, L. Parsons

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

IN the summer rainfall region of the pastoral areas lambs are too often born too late to ensure their survival.

In good seasons with a fair measure of winter rain more late lambs will survive, but losses are still serious. The only solution to this problem is to make sure lambs drop in May-June.

But the presence of late and often unmarked lambs at mating time is a disturbing influence, which makes it hard to advance the established mating pattern.

One Shot Baiting, C D. Gooding, L. A. Harrison

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

THE Agriculture Protection Board introduced the first of its contract poisoning schemes in 1955 in the lower South-West when three units undertook the first "1080" poisoning for farmers in Western Australia.

The originators of one-shot baiting describe this new technique and explain how it should be used for best results on the farm.

Attack The Rabbit At Home : Destroy Warrens And Harbourage, J S. Crawford

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

Effective rabbit destruction often calls for a carefully worked out control programme consisting of poisoning, fumigating and warren and harbourage destruction.

Possibly the most effective means of not only controlling rabbits but ultimately eradicating them from holdings is the destruction of warrens and harbourage.

The Fox : Status And Control, C D. Gooding

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

NOBODY knows for certain and it is possible that the damage done by foxes is sometimes over-rated, but the fact remains that foxes are reputed to be a real problem to some farmers at lambing time.

Dingo Control : Organised Ground Baiting Drives At Mating Time, C D. Gooding, J. J. Freeth

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

DINGOES in Western Australia, like all "creatures of nature", have a well defined seasonal pattern of behaviour.

This is influenced somewhat by weather variations, but even in remote areas where violent fluctuations in rainfall occur from year to year, the dingo still breeds at roughly the same time.

The numbers of pups born and the numbers which survive each year varies a lot, but life goes on at roughly the same tempo under most seasonal conditions.

An Assessment Of Cattle Husbandry Problems In Western Australia, W J O Wilkie

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

Spraying For Grasshopper Control, T J. Tozer

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

A BIG increase in cereal growing in the "hopper" belt has brought a general improvement in the grasshopper situation over the past few years.

This highlights the emphasis entomologists have placed on cultivation as the best known way of controlling grasshoppers.
