Opposed Disc Plough Furrows Hard Kimberley Soils, Department Of Agriculture, Western Australia Jan 1964

Opposed Disc Plough Furrows Hard Kimberley Soils, Department Of Agriculture, Western Australia

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

THE work of reclaiming the eroded areas of the Ord River catchment has posed special problems for field staff of the Department of Agriculture engaged on this large scale project.

Thousands of miles of furrows must be contour-ploughed and seeded in extremely hard ground over big areas of eroded country.


Planning New Farm Dams : Excavated Earth Tanks, J E. Watson, J. C. Grasby Jan 1964

Planning New Farm Dams : Excavated Earth Tanks, J E. Watson, J. C. Grasby

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

A GOOD farm dam is a valuable asset, and well worth its cost, but there are many aspects to consider when a new dam is required. Careful planning with adequate testing and checking will help to get the best value for money and reduce the chance of costly failures.

This article discusses these aspects in relation to the excavated earth tank type of dam.


The Quality Of Groundwaters In The Central Wheatbelt Of W.A, Eric Bettenay, F. J. Hingston Jan 1963

The Quality Of Groundwaters In The Central Wheatbelt Of W.A, Eric Bettenay, F. J. Hingston

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

IN south-western Australia permanent rivers are virtually absent and the larger drainage systems such as the Swan-Avon, Murray and Blackwood, which have their headwaters in inland low rainfall areas, are generally saline.


A Review Of Agriculture On The Esperance Downs, J L. Shier, T. C. Dunne, E. N. Fitzpatrick Jan 1963

A Review Of Agriculture On The Esperance Downs, J L. Shier, T. C. Dunne, E. N. Fitzpatrick

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

Esperance is approaching a period of rapid development based on the results of research at Esperance Downs Research Station and on farmers' properties in the area.

This article reviews the soils, vegetation, climate, agricultural development and development costs of the area.


The Gascoyne River Catchment Area, W M. Nunn Jan 1962

The Gascoyne River Catchment Area, W M. Nunn

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

A RECENT Department of Agriculture survey of the Gascoyne River catchment area has indicated that deterioration of plant cover in the area contributes to the severity of floods which regularly damage the town of Carnarvon.

It is hoped that the results of the survey will help efforts to regenerate the catchment area, and reduce the risk of flooding.


Stilling Coastal Sand Drifts With Marram Grass, J L. Mcmullan Jan 1962

Stilling Coastal Sand Drifts With Marram Grass, J L. Mcmullan

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

DRIFTS in dunes on the coast between Albany and Geraldton may be stabilised by planting marram grass (Ammophila arenaria).

However, it should be anticipated that much of the planted grass will die before an area is finally stabilised.


Light Lands In Western Australia. 2. Their Nature, Distribution And Climate, George Henry Burvill Jan 1962

Light Lands In Western Australia. 2. Their Nature, Distribution And Climate, George Henry Burvill

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

LIGHT land development for agriculture is a major feature in the story of agriculture in Western Australia. Sixty years ago there was less than one million acres of arable land.

The total area planted to all crops was less than 250 thousand acres and the wheat harvest was less than one million bushels.


Loss Of Structure In Wheatbelt Soils, T C. Stoneman Jan 1962

Loss Of Structure In Wheatbelt Soils, T C. Stoneman

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

MANY of the heavy soils of the West Australian wheatbelt have been farmed for 30 or 40 years, and farmers now frequently complain that these soils are becoming more difficult to handle, that greater power is needed to break up the soil, and the time that it remains in a workable condition after rains is shorter.


Care Of Autumn And Winter Tomato Crops, W H. Kooyman Jan 1962

Care Of Autumn And Winter Tomato Crops, W H. Kooyman

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

I N recent years there has been a considerable increase in plantings of autumn and winter tomatoes in the Perth metropolitan market garden area.


Light Lands In Western Australia. 1. History And Future Prospects, F L. Shier Jan 1962

Light Lands In Western Australia. 1. History And Future Prospects, F L. Shier

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

BECAUSE of the scattered distribution of light lands of the agricultural areas of Western Australia among the better soils, and their large total area, it is not surprising that attempts to develop these unattractive soils for agriculture started many years ago.


Good Pasture On A Problem Soil, R Sprivulis Jan 1961

Good Pasture On A Problem Soil, R Sprivulis

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

The acid peaty sands of the South-West have always been problem soils, and are often considered useless.

But, by following recommended establishment methods, farmers like Mr. F. E. Bellanger, of Nornalup, have shown that it can carry valuable pasture.


Natural Paddocks Help Soil Conservation, G W. Spencer Jan 1961

Natural Paddocks Help Soil Conservation, G W. Spencer

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

ON most farms, particularly in the cereal and sheep districts, the paddocks as we know them are fenced off into neat squares or rectangles.

The original fencing was done in such a way that the paddock layout, as well as the fences, completely disregards the topography or natural features of the land. Often this has encouraged soil erosion.

In properly laid out paddocks there should be a very close relationship between the natural features of the farm, the fence plan, and soil conservation.


Establishing Saltland Pastures, C V. Malcolm Jan 1961

Establishing Saltland Pastures, C V. Malcolm

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

WITH the approach of winter, thoughts are turning to the seeding season. It will therefore be appropriate to discuss methods of establishing saltland pastures.

This discussion will be restricted to "bluebush," creeping saltbush, and old man saltbush. Seed of these plants is available from local stock firms.


Healthy Pastures, F E. Ryan Jan 1961

Healthy Pastures, F E. Ryan

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

IN sweeping away forests to make room for pastures we have taken on the responsibility of maintaining these areas in a condition suitable for the growth of pasture plants.

This is done by a choice of suitable species, fertilising, cultivating, drainage, control of grazing and by weed and insect control.


Fallowing And Soil Conservation, J E. Watson Jan 1961

Fallowing And Soil Conservation, J E. Watson

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

Soil Conservationists don't always disapprove of fallowing, says Soil Conservation Service adviser J. E. Watson.

They are prepared to compromise, and accept fallowing as a useful practice where it means better pasture establishment or more effective land reclamation.


Salty Seepages Can Be Productive, C V. Malcolm Jan 1961

Salty Seepages Can Be Productive, C V. Malcolm

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

MUCH has been said and written concerning the use of Paspalum vaginatum for growing on seepage areas, but the general production to be expected from seepage areas has not received much attention.

The fact is that properly handled, seepage areas can be quite productive, and can be valuable for summer grazing.


Manage Your Rainfall For Maximum Production, J E. Watson Jan 1961

Manage Your Rainfall For Maximum Production, J E. Watson

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

TTOW much would an extra inch of rainfall be worth to you? Much sloping land loses this much and more by run-off every year.

The soil is the main asset of your farm, but your profits depend on how you manage the rain which falls on it.


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.


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.


Leaflet No 1003 - The Salt Problem In The Wheat Belt, G. H. Burvill Jan 1950

Leaflet No 1003 - The Salt Problem In The Wheat Belt, G. H. Burvill

Bulletins 1 - 2999

IN the wheat belt of Western Australian bare patches in farm paddocks are often seen. Many are bare, or almost bare, because of too much salt in the soil. The excess of salt prevents the germination of seeds, or kills living plants, because it causes the water supply for germination or growth to be cut off. This salt problem is so serious in places that single farms or groups of farms have been ruined; wheat growing on them has become unprofitable.


Report Of The Geologist, Erwin Hinckley Barbour Jan 1896

Report Of The Geologist, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

THE PROBLEM OF OUR SOILS AND SOIL MOISTURE.

The soil survey of the state, which was begun by the author in November of 1892, has progressed to the point where it might be considered finished. That is, one or more samples of soils have been taken from every distinct soil region in the state-in fact, most of the separate counties are represented, and mechanical analyses of many of these have already been made. However, in consideration of the size of our counties, the work will not be declared complete until each is represented in the state museum by soil prisms …
