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.
Bluebush Seed : Cleaning, Drying And Storing, C V. Malcolm
Bluebush Seed : Cleaning, Drying And Storing, C V. Malcolm
Journal of the Department of Agriculture, Western Australia, Series 4
BLUEBUSH (Kochia brevifolia) is a perennial plant which occurs naturally in Western Australia.
In the past it has attracted little attention, but in recent years it has created interest as a highly nutritious and salt tolerant plant well adapted to certain salt affected soils in the wheatbelt.
A previous article (Bulletin No. 2630) by Smith and Malcolm drew attention to its use. One of the problems in establishing bluebush is to obtain seed supplies.
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.
Reclaim Salty Soils With Bluebush, Department Of Agriculture, Western Australia
Reclaim Salty Soils With Bluebush, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
BLUEBUSH (Kochia brevifolia) is an Australian plant which can produce good yields of excellent feed when grown on grown well drained salty soils in the 12 to 15-inch rainfall districts of Western Australia.
Potatoes Sprinkler Irrigated From The Collie River, John W. Lewis
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
The background to Western Australia's soil salinity problems, and a description of the main types of salt-affected land, by Senior Soil Research Officer, S. T. Smith, B.Sc. (Agric.)
Thirsty Cows Are Poor Milkers, S R. Dunstan
Thirsty Cows Are Poor Milkers, S R. Dunstan
Journal of the Department of Agriculture, Western Australia, Series 4
THE HOT summer weather is not far away, and now is a good time for the whole milk producer to attend to those points which will ensure that milk production is maintained at a high level during this period.
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.
A Rational Approach To The Estimation Of Evaporation And Evapotranspiration From Climatological Data, Jerald Emmet Christiansen, B. B. Patil
A Rational Approach To The Estimation Of Evaporation And Evapotranspiration From Climatological Data, Jerald Emmet Christiansen, B. B. Patil
Reports
Many attempts have been made to derive mathematical expressions relating evaporation and evapotranspiration, or consumptive use, to climatological data. IN the United States, the Blaney-Criddle formula is probably the best known for estimating consumptive use (2 and 3). Blaney (1) has also suggested that this formula is suitable for estimating evaporation as measured with a Weather Bureau pan. Other well known formulas are the Penman formulas (10), the Thornthwaite formula (15) and the Hargreaves formulas (8). Halkias, Beihmeyer and Hendrickson (6) suggest that water requirements of crops can be determined from atmometer data. Lowry and Johnson (() in an early …
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.

Contour Banks For Filling Dams, B A'B Marsh
Contour Banks For Filling Dams, B A'B Marsh
Journal of the Department of Agriculture, Western Australia, Series 4
A LTHOUGH contour banks have been used in this State for many years to lead water into earth tanks or "dams," it is only comparatively recently that the idea has become really popular.
Thanks to the publicity given to this matter during the last three years many farmers now know that dams may be filled by contour banks, but because they do not know the finer points of the method, they are apt to mislead themselves into thinking that their territory is unsuitable for putting it into practice.
Rabbit Control In 1960, C Marshall
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.
Drought Feeding Of Sheep, Laurence C. Snook
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 …
Reclaiming Salt Land With Bluebush, Stanley Thomas Smith
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.
Bluebush Seed Supplies, C V. Malcolm
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.
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.
Deferred Grazing : What It May Mean In The Mulga Region, W M. Nunn
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.
Wild Life In A Modern Age, Clee Francis Howard Jenkins
Wild Life In A Modern Age, Clee Francis Howard Jenkins
Journal of the Department of Agriculture, Western Australia, Series 4
THE present human population of the earth is estimated at about 2 1/2 thousand million, and reliable sources consider that this figure will be doubled by the year 2000.
Although the pessimistic forecasts of Malthus have not yet come true, it is obvious that the world's food requirements, must lead to increased exploitation of land and other primary resources, with consequent repercussions on all forms of wild life.
Weed Research. 7. Weed Control Around The Yard, Geoffrey A. Pearce
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.
