Cost Of Farm Water Supplies : Conclusions From Surveys, I A F Laing
Cost Of Farm Water Supplies : Conclusions From Surveys, I A F Laing
Journal of the Department of Agriculture, Western Australia, Series 4
The Department of Agriculture, in conjunction with the Farm Water Supply Advisory Committee, has conducted farm wster supply surveys in many districts in the wheatbelt.
The aim of the surveys was to collect data to assess the existing water supplies, the potential for further water supply developments and to compare the relative difficulty of water supply development in different localities.
Conservation Of The National Estate, Department Of Agriculture, Western Australia
Conservation Of The National Estate, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
In 1973 the Australian Government established a Committee of Inquiry under Mr. Justice R. M. Hope to inquire into the National Estate. Under its terms of reference the Committee was to assess the nature and condition of the National Estate and the measures which were being and should be taken for its preservation and enhancement.
Officers of the Department of Agriculture recognise that there are basic natural resources such as land, water, gene material and ecosystems which are essential elements of the National Estate held in trust by successive generations.
In a submission to the Inquiry, matters of particular concern …
Irrigating With Underground Water, T C. Calder
Irrigating With Underground Water, T C. Calder
Journal of the Department of Agriculture, Western Australia, Series 4
MANY farmers in South-West areas are looking to irrigation to increase and diversify farm production, particularly on the sandy coastal plain where irrigation in summer is essential for vegetable, fruit and fodder production.
Water Conservation : The Storage Life Of Farm Dams, D J. Carder
Water Conservation : The Storage Life Of Farm Dams, D J. Carder
Journal of the Department of Agriculture, Western Australia, Series 4
HOW MANY stock can a dam of a certain size and depth be expected to carry and how long will the supply last?
What size of dam is needed in case the winter rains fail? How many stock can a dam support and still provide a drought supply?
Water Storage Has Not Kept Pace With Stock Numbers : South Stirling Survey Finding, A L. Prout
Water Storage Has Not Kept Pace With Stock Numbers : South Stirling Survey Finding, A L. Prout
Journal of the Department of Agriculture, Western Australia, Series 4
RESULTS of a survey on water storage capacity in the South Stirlings area indicate that farm water storage has not kept pace with increased clearing and stock numbers.
This has resulted in many farmers requesting advice on water conservation projects following two consecutive years of low rainfall runoff.
The Ord River Regeneration Project. 3. Eight Years Of Progress, K Fitzgerald
The Ord River Regeneration Project. 3. Eight Years Of Progress, K Fitzgerald
Journal of the Department of Agriculture, Western Australia, Series 4
REGENERATION of degraded areas in regions of marginal rainfall is a slow process under the best of conditions, but on the Ord River Catchment, where much top-soil had been removed, the problem was unusually severe.
In many areas top-soil will have to be rebuilt before vegetation can be re-established.
This will be a long, slow process and regeneration will proceed through gradual plant succession from the "pioneer" annual species through to the permanent and more productive perennial species needed for a stable catchment area.
Irrigation In The South-West : Report On Government-Controlled Areas, 1965-66, G Gauntlett
Irrigation In The South-West : Report On Government-Controlled Areas, 1965-66, G Gauntlett
Journal of the Department of Agriculture, Western Australia, Series 4
LARGE scale irrigation in the south-western part of Western Australia is confined to the coastal plain, west of the Darling Range where the three irrigation districts of Waroona, Harvey and Collie have been established.
Soil Erosion By Water In W.A. Cropland : A Serious And Widespread Problem, Department Of Agriculture, Western Australia
Soil Erosion By Water In W.A. Cropland : A Serious And Widespread Problem, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
Much wheatbelt agriculture is based on thin topsoils which are inherently infertile by world standards. Erosion even to the depth of cultivation will cause the loss of:—
• most of the original topsoil
• the phosphate build up from years of "super" applications
• any accumulation of organic matter and humus.
Soil Conservation : Build Contour Banks With A Disc Plough, G W. Spencer, D. J. Carder
Soil Conservation : Build Contour Banks With A Disc Plough, G W. Spencer, D. J. Carder
Journal of the Department of Agriculture, Western Australia, Series 4
Heavy earthmoving machinery is not necessary for contouring; most farmers are already equipped to do the job themselves.
This article by soil conservation advisers G. W. Spencer and D. J. Carder tells how to build contour banks with a disc plough.
Land Preparation For Border Irrigation, B Swan
Land Preparation For Border Irrigation, B Swan
Journal of the Department of Agriculture, Western Australia, Series 4
LARGE amounts of water may be lost through excess run-off and deep percolation.
Proper preparation of irrigation land can help to minimise these losses.
This preparation is done by grading or levelling so that the original ground surface is shaped to allow for a more uniform distribution of water.
Farm Dams In The Wheatbelt, J E. Watson
Farm Dams In The Wheatbelt, J E. Watson
Journal of the Department of Agriculture, Western Australia, Series 4
MANY new farm dams are sunk each year in the wheatbelt and much money is spent on them.
With continued development of new land, and increasing stock carrying capacity of older land under legume pastures, the need for more water supplies will continue for a long time.
Water For Agriculture. 2. Plants For Salty Water, C V. Malcolm
Water For Agriculture. 2. Plants For Salty Water, C V. Malcolm
Journal of the Department of Agriculture, Western Australia, Series 4
ALL natural water supplies contain dissolved salts. In wet climates these salts are usually not present in sufficient quantity to cause plant damage.
However, in Western Australia many natural water supplies contain harmful amounts of dissolved salts.
Water For Agriculture. 4. Clearing Cloudy Or Muddy Water, R C. Gorman
Water For Agriculture. 4. Clearing Cloudy Or Muddy Water, R C. Gorman
Journal of the Department of Agriculture, Western Australia, Series 4
Water made cloudy by finely divided clay, silt or organic matter in suspension may be cleared by simple chemical treatment.
The selection of a satisfactory treatment is often a matter of practical testing.
Water For Agriculture. 3. Watering Plants With Salty Water, Stanley Thomas Smith
Water For Agriculture. 3. Watering Plants With Salty Water, Stanley Thomas Smith
Journal of the Department of Agriculture, Western Australia, Series 4
In Western Australia it is often necessary to use saline water for irrigation and gardening because of the lack of better water.
Two factors influence the results achieved. One is the selection of suitable plants, the other is the way in which the water is used.

Manage Your Rainfall For Maximum Production, J E. Watson
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.
Overcoming Stock Watering Problems In The Kimberleys, B Swan
Overcoming Stock Watering Problems In The Kimberleys, B Swan
Journal of the Department of Agriculture, Western Australia, Series 4
ONE of the ever-present problems of the pastoral areas is that of providing: watering-points in reasonably close proximity to the grazing areas.
All too frequently, the country on the river frontages and that in the vicinity of the water-holes becomes eaten out and although there may be ample feed on other portions of the run, it is too far distant from the available water to be effectively utilised.
Water Usage Trials With Bananas On The Gascoyne, W M. Nunn
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.
