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.
Paspalum Vaginatum For Salty Seepages, C V. Malcolm
Paspalum Vaginatum For Salty Seepages, C V. Malcolm
Journal of the Department of Agriculture, Western Australia, Series 4
Paspalum vaginatum, aptly termed "sea shore paspalum" has over the last fifteen years shown an amazing ability to thrive in wet salty situations.
Seed of the grass is not available but it may easily be established by planting pieces.
This article reviews where and how the grass may be used.

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.

Winter Management Of Salt Land, T C. Stoneman
Winter Management Of Salt Land, T C. Stoneman
Journal of the Department of Agriculture, Western Australia, Series 4
WITH the emergence of crops, many farmers will again be seeing bare patches or thin stands of cereals due to salt accumulation.
Would these areas be better left out of cultivation, or should they have been planted to saltbush and bluebush?
Farm Flora Sancturies, Robert Dunlop Royce
Farm Flora Sancturies, Robert Dunlop Royce
Journal of the Department of Agriculture, Western Australia, Series 4
NOW that several species of native plants have become totally extinct and many more are becoming rare almost to the point of extinction, interest in the scientific and aesthetic potential of the West Australian flora is awakening.
Loss Of Structure In Wheatbelt Soils, T C. Stoneman
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.

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.
Water Conservation On The Farm, John W. Lewis
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.
Good Pasture On A Problem Soil, R Sprivulis
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.

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.
Flooding Of Salt Land, C V. Malcolm
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.
Natural Paddocks Help Soil Conservation, G W. Spencer
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.
Fossils And Farmers, D Merrilees
Fossils And Farmers, D Merrilees
Journal of the Department of Agriculture, Western Australia, Series 4
The West Australian Museum is looking for fossil remains from the Pleistocene age, the period of geological time when Europe was covered with ice.
Little is known of what the Australian continent was like at that time, and the Museum hopes, by collecting as many fossil remains as possible, to get a better picture of Australian conditions at that time.
It is also hoped to discover more about the ancestors of our present marsupial fauna.
Farmers may be able to make a valuable contribution to the present knowledge of this period by forwarding suspected fossil remains to the Museum. Here …
Palatability Of Forage Plants In North-West Sheep Pastures, R H. Collett
Palatability Of Forage Plants In North-West Sheep Pastures, R H. Collett
Journal of the Department of Agriculture, Western Australia, Series 4
A DECLINE in carrying capacity has occurred in large areas of the Pilbara district of the North-West, due to the decrease in palatable plants and the increase in unpalatable ones.
The relative palatability of the various species to sheep is therefore a matter of considerable importance to pastoralists.
Soil Salinity In Western Australia, Stanley Thomas Smith
Soil Salinity In Western Australia, Stanley Thomas Smith
Journal of the Department of Agriculture, Western Australia, Series 4

Establishing Saltland Pastures, C V. Malcolm
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.
Is Your Water Supply Safe?, D C. Mickle
Is Your Water Supply Safe?, D C. Mickle
Journal of the Department of Agriculture, Western Australia, Series 4
THERE can be no doubt in anyone's mind that the need for a clean, safe and adequate water supply is essential for the production of high quality milk and cream.
It naturally follows, that, even though every possible care has been taken in an endeavour to produce clean, germ-free milk and cream, contamination by bad water can render these efforts void.
Automatic Waterers For Day Old Chickens, P Smetana, W. Ward
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.
Fossils And Farmers. 2. The Ice Age, D Merrilees
Fossils And Farmers. 2. The Ice Age, D Merrilees
Journal of the Department of Agriculture, Western Australia, Series 4
What did the giant Australian marsupials of the "Ice Age" look like?
Fossil remains found by farmers could help reconstruct them, as well as giving some idea of conditions on the Australian continent at that time, says D. Merrilees, B.Sc, acting Curator of Palaeontology at the West Australian Museum.
Healthy Pastures, F E. Ryan
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
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
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
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.
