Rabbit Control In 1960, C Marshall Jan 1960

Rabbit Control In 1960, C Marshall

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

IN the year 1859, an enthusiastic sportsman in Victoria took delivery from the clipper "Lightning" of a small consignment of wild European rabbits which he joyfully released on his estate at Barwon Park, near Geelong, in order to assure himself of some rough shooting.

He was not the only rabbit importer on record—tame rabbits were brought into Australia before and after 1895 and doubtless there were other importations of the wild rabbit—but he is generally credited—or discredited—with having triggered off the rabbit plague.


A Useful Farm-Made Roller, V E. Western Jan 1960

A Useful Farm-Made Roller, V E. Western

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

A very serviceable compacting roller can be constructed at little expense by using discarded truck tyres.

The roller described here has an overall width of 5 ft. 3 in. and carries seven 9.00 x 24 semi-trailer tyres which had been discarded when the treads were worn smooth.


Feeding Pickled Wheat To Pigs, Department Of Agriculture, Western Australia Jan 1960

Feeding Pickled Wheat To Pigs, Department Of Agriculture, Western Australia

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

INQUIRIES are frequently received from farmers asking whether it is safe to feed pickled wheat to pigs, and if so, the quantities which would be suggested.

Until very recently there was no experimental information on the safety or possible dangers of these wheat pickling agents, but feeding trials completed last year at the Animal Health and Nutrition Laboratory, Nedlands, have provided some of the answers to these questions.


Studies In The Mulga Pastoral Zone. 1. The Grazing Of Wandarrie Grass Associations, D G. Wilcox Jan 1960

Studies In The Mulga Pastoral Zone. 1. The Grazing Of Wandarrie Grass Associations, D G. Wilcox

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

THE establishment of the Wiluna office of the North-West Branch marked the commencement of a series of investigations into the pastures of the mulga zone.

Unlike the agricultural areas where a fund of knowledge exists on the growth habits of the pastures, the pastures of this area were completely unknown.

The preliminary investigations had to be aimed at forming an understanding of the reactions of the various plants to rain, to temperature and seasonal conditions and to grazing in an area of extremely low rainfall reliability.


Facts And Figures For The Man On The Land, J A. Mallett Jan 1960

Facts And Figures For The Man On The Land, J A. Mallett

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

FARM or station life calls for the exercise of so many different skills that the farmer or pastoralist is usually an accomplished handyman.

For those whose schooldays are far behind them however, the most difficult part of many tasks is that of dealing with the calculations involved, and it is hoped that these facts and figures will serve as a handy aid to those whose mathematical ability has not kept pace with their manual and technical skill.


Reclaiming Salt Land With Bluebush, Stanley Thomas Smith Jan 1960

Reclaiming Salt Land With Bluebush, Stanley Thomas Smith

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

IN Western Australia there are approximately a million acres of salt land, some of which is a serious economic problem to individual farmers, unfortunate enough to have the major portion of their properties affected by salt encroachment.


Weed Research. 7. Weed Control Around The Yard, Geoffrey A. Pearce Jan 1960

Weed Research. 7. Weed Control Around The Yard, Geoffrey A. Pearce

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

MANY farmers and city householders have weed problems around houses and sheds which can be readily overcome by treatment with appropriate herbicides.

The risk from fire through weeds and unslightly growth can easily be removed and an area free of any plant growth can be maintained with little effort for a considerable period.


Irrigation In Western Australia : Report On Government-Controlled Areas : 1958-59, H K. Gibsone Jan 1960

Irrigation In Western Australia : Report On Government-Controlled Areas : 1958-59, H K. Gibsone

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

IRRIGATION in the south-western portion of Western Australia is mainly confined to the coastal plain west of the Darling Range where the three main irrigation districts of Harvey, Collie and Waroona have been established by the State Government.

The Government-controlled irrigation areas extend southward from Waroona (70 miles from Perth) to Dardanup (120 miles from Perth) and have an average width of about five miles.


Kimberley Research Station : A Progress Report, Department Of Agriculture, Western Australia Jan 1960

Kimberley Research Station : A Progress Report, Department Of Agriculture, Western Australia

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

INTEREST in the agricultural potential of the Kimberley region in Western Australia dates from its early exploration and settlement in the last century.

Several farming development schemes were considered for the area, but were never implemented.

This could be mainly attributable to lack of knowledge of agricultural potentialities, limitations of the local environment and ways of exploiting the local environment.

Up to the present the economy of the region is almost entirely based upon the extensive production of beef and to a lesser extent, wool.


Some Results With Nitrogen Fertiliser On Cereals At Esperance Plain Research Station, William John Toms Jan 1960

Some Results With Nitrogen Fertiliser On Cereals At Esperance Plain Research Station, William John Toms

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

ON newly-cleared land at Esperance Plain Research Station the use of sulphate of ammonia on cereals has proved profitable over a number of seasons.

The response to sulphate of ammonia varies markedly with the season.


Drought Feeding Of Sheep, Laurence C. Snook Jan 1960

Drought Feeding Of Sheep, Laurence C. Snook

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

WHEN this talk on drought feeding of sheep was suggested conditions were very serious over large tracts of pastoral country.

Many stations had not received a worthwhile rain for over 12 months and it appeared that grazing animals would have to be fed if they were to survive.

Requests have been received for advice on the cheapest way to keep sheep alive. Drought feeding in any form is a gamble. There is always the risk that the stock will eventually die despite the consumption of much costly feed.

It follows that if an effort is to be made to save …


Water Usage Trials With Bananas On The Gascoyne, W M. Nunn Jan 1960

Water Usage Trials With Bananas On The Gascoyne, W M. Nunn

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

THE banana industry at Carnarvon is an unusual one by most agricultural standards.

Normally a tropical plant liking relatively humid conditions in a high rainfall, the banana is cultivated at Carnarvon in an area of extremely low rainfall and with relatively low humidity throughout the year.

Water is pumped to irrigate the crop from the sands of the Gascoyne River bed or from bores adjacent to the river course.


Bluebush Seed Supplies, C V. Malcolm Jan 1960

Bluebush Seed Supplies, C V. Malcolm

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

A GREAT deal of publicity has been given of late to the value of bluebush (Kochia brevifolia) as a plant for some types of salt-affected land, particularly in the drier parts of the wheatbelt.

Obtaining seed supplies can be a problem, but fortunately large amounts of seed are not required since once a few bushes are established they will spread seed over the intervening areas.

Thus rates of 1 to 2 lb of seed per acre have been found quite satisfactory.


Deferred Grazing : What It May Mean In The Mulga Region, W M. Nunn Jan 1960

Deferred Grazing : What It May Mean In The Mulga Region, W M. Nunn

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

THE practice of deferred grazing has been written up in American textbooks and has been applied effectively to sections of the cattle range lands of the United States.

Early attempts to apply the principle in eastern Australia were not very successful, and it remained for our Departmental workers in the North-West and Kimberley Divisions to demonstrate the phenomenal results that could be obtained on grasslands in summer rainfall areas.


Black Spot Of Tomatoes, R F. Doepel Jan 1960

Black Spot Of Tomatoes, R F. Doepel

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

BLACK SPOT DISEASE IS THE MOST SERIOUS FOLIAGE BLIGHT OF TOMATOES IN THIS STATE. IN SEASONS FAVOURABLE TO ITS DEVELOPMENT SEVERE DEFOLIATION AND FRUIT ROTTING ARE EXPERIENCED.

IN Western Australia, black spot, which is also known as early blight and target spot, is a troublesome disease of long standing. It is caused by the fungus Alternaria solani which also attacks potatoes.


List Of Registered Fertilisers : 1959-60, H G. Cariss Jan 1960

List Of Registered Fertilisers : 1959-60, H G. Cariss

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

TN accordance with the provisions of the Fertilisers Act, 1928-1955, it is required that—with the exception of bulk sales to a manufacturer and those made in accordance with a buyer's written prescription—all fertilisers sold are required to be registered annually, the registration year being from November 1 to October 31 following.

The list of fertilisers registered for the year commencing November 1, 1959, is set out herewith in tabular form.


Commercial Vegetable Growing In The Perth Metropolitan Region, L T. Jones Jan 1960

Commercial Vegetable Growing In The Perth Metropolitan Region, L T. Jones

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

MARKET gardening with sprinkler irrigation on deep sandy soils around Perth is really a commercial application of hydroponics or sand culture principles.

Provision of a continuous and adequate supply of nitrogen is the major problem. Peat swamps scattered among the sandy areas have higher natural fertility. However, their common problems are drainage, acidity ("sourness"), salt and various special soil deficiencies. Over-liming of acid swamps can cause new problems.


The Development Of Western Australian Sand Plain Soils For Agriculture, Richard Philip Roberts, F. L. Shier Jan 1960

The Development Of Western Australian Sand Plain Soils For Agriculture, Richard Philip Roberts, F. L. Shier

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

IN a recently published economic survey of the Australian wheat growing industry, it was reported that nearly two-thirds of the farms surveyed in Western Australia were located on lateritic "sand plain."

As a random selection was made of the eighty farms that were visited it is reasonable to conclude that a similar proportion of all the State's wheat producing farms are on that type of country.

This constitutes a remarkable change from the earlier days of wheat belt settlement when the sand plain soils were regarded as virtually useless and by-passed for development.

It is the purpose of this article …


Soil Conservation In The Kimberley Area Of Western Australia, K Fitzgerald Jan 1960

Soil Conservation In The Kimberley Area Of Western Australia, K Fitzgerald

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

OFFICERS of the Soil Conservation Branch of the West Australian Department of Agriculture, have not been engaged in soil conservation work in the Kimberleys prior to this year, not because a serious erosion problem did not exist, but rather because with limited trained staff available they were too fully occupied elsewhere.

The recent arrival of a senior Soil Conservation Officer in the area to assist and plan an approach to the problem of soil erosion in the Ord River catchment area is therefore very welcome.


Opposed Discs For Furrowing In Pastoral Areas, W. M. Nunn Oct 1959

Opposed Discs For Furrowing In Pastoral Areas, W. M. Nunn

Journal of the Department of Agriculture, Western Australia, Series 3

THROUGHOUT our pastoral regions in all land divisions from Murchison to Kimberley, there are extensive areas of bare country which must be broken in some way to enable water penetration and to provide a place for seed to lodge before regeneration of pasture species can be expected. Earlier articles in this Journal have explained the occurrence of these bare areas, and described methods of furrowing. Checkerboard designs have been successful on perfectly level locations but contouring becomes essential where there is a slope of any dimension.


Granular Fertiliser, C R. Hale Aug 1956

Granular Fertiliser, C R. Hale

Experimental Summaries - Plant Research

There is general agreement that granulation of fertilisers improves their physical characteristics with respect to handling, storage and distribution in the field. These physical advantages rather tan any established agronomic reason appear to be responsible for the increasing use of granular fertiliser.


Heavy Rains Show Need For Soil Conservation Practices, G H. Burvill May 1953

Heavy Rains Show Need For Soil Conservation Practices, G H. Burvill

Journal of the Department of Agriculture, Western Australia, Series 3

Autumn 1953 will stand out in the weather records for the widespread heavy rains in the pastoral areas and wheatbelt. The rains which came from the cyclonic storms of March 22-25, totalled five to 12 inches in many pastoral areas and two to seven inches in the Northern and Eastern Wheatbelt. The steady rain soaked the land, but where the falls were heaviest, runoff to lower parts caused flooding and local inconvenience. All in all, it was a very welcome rain, especially where the previous winter had been dry. In the wheatbelt, ploughing and cultivation were soon in full swing …


Make The Best Use Of Your Rainfall, J E. Watson Mar 1953

Make The Best Use Of Your Rainfall, J E. Watson

Journal of the Department of Agriculture, Western Australia, Series 3

Farmers are not always satisfied with the rain that falls on their farms—it is often too little, too much, too soon or too late. However, the farmer has a very great responsibility to make the best use of the rain he gets, and if he gets too much, to see that the excess can flow down to the rivers without causing damage.


The Soil Our Basic Asset, J E. Watson Mar 1953

The Soil Our Basic Asset, J E. Watson

Journal of the Department of Agriculture, Western Australia, Series 3

Contour furrows increase pasture growth

Good pastures on steep slopes will give profitable returns from grazing, and will also reduce erosion risks. Water needed for pasture growth on such slopes must not be allowed to run off and erode lower slopes. The use of contour furrows is a readily applied erosion control measure which can be very effective in increasing the amount of water held and absorbed on steep slopes.

Wind Erosion Control—I, D J. Fleay Jan 1953

Wind Erosion Control—I, D J. Fleay

Journal of the Department of Agriculture, Western Australia, Series 3

Desserts have been formed in some parts of the world by the action of wind on once productive soils. This could happen to the light land areas of Western Australia if we do not profit by the lessons of the past and manage these soils with great care.

Soil Conservation Service - Basis Of Co-Operation, G H. Burvill Nov 1952

Soil Conservation Service - Basis Of Co-Operation, G H. Burvill

Journal of the Department of Agriculture, Western Australia, Series 3

The Soil Conservation Service has been established as provided in the Soil Conservation Act, 1945. To carry out its objectives will require the co-operation with it of individual farmers and landholders. The policy of the Service is therefore to encourage farmers to help themselves, and particularly to encourage them to recognise the need for soil conservation methods and for soil erosion control in the early stages. More particularly, the Service aims to provide, through its trained staff, technical asistance in the way of agricultural advice, research, conservation, planning, layouts and surveys. As indicated below, under the heading "Charges for Soil …


The Regeneration And Maintenance Of Wimmera Ryegrass Pastures Under Saline Soil Condition, F L. Shier Nov 1952

The Regeneration And Maintenance Of Wimmera Ryegrass Pastures Under Saline Soil Condition, F L. Shier

Journal of the Department of Agriculture, Western Australia, Series 3

Over the past ten years, Wimmera ryegrass pastures at the Salmon Gums Re- VJ search Station have been improved and maintained by periodic cultivation of the soil even without applications of superphosphate. On heavy crab-holey soil affected by high salt content and unsatisfactory for wheat growing, cultivation treatments have produced remarkably uniform stands of Wimmera ryegrass as shown in the accompanying pictures. The bare patches due to salt, have been largely eliminated. If the interval between cultivations is more than three years Wimmera pastures deteriorate badly.
