Set Stocking Has A Place In Soil Conservation Farming, J E. Watson

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

Set stocking of sheep at increased stocking rates is rapidly becoming popular with farmers in the agricultural areas of Western Australia.

But will set stocking increase soil erosion hazards? It should do just the reverse, according to Soil Conservation Adviser J. E. Watson, B.Sc, who claims that set stocking has a place in soil conservation farming.

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.

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.

Progress In The Control Of Cotton Fireweed, Geoffrey A. Pearce

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

Cotton Fireweed (Erechtites quadridentata) is native to Western Australia and was first collected by Drummond before 1850. In its natural habitat it is quite insignificant and passes unnoticed.

Cotton fireweed, a native perennial plant, has become a serious weed in the south coastal districts and is now one of the most widespread weeds in the State.

Swing Fence Flood Crossing For Creeks In The Kimberleys, A L. Payne

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

FENCING is the basis of the regeneration programme on the eroded Ord River catchment area, and the fences constructed must cross numerous creeks.

But heavy downpours of short duration characterise the wet season experienced in this area.

Because the rain falls on to bare, compacted ground, run-off is intense and gullies and creeks rise rapidly, causing serious damage to conventional fences and flood gates across watercourses.

A History Of Nebraska's Fishery Resources, David J. Jones

Profitable Returns From Saltland, C V. Malcolm

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

The recent saltland survey disclosed that about 305,000 acres of land previously cleared and sown had become salt affected.

This represents a serious loss in production but is offset by the fact that much of the land is capable of producing high yields of good quality fodder.

Water For Agriculture. 5. Salt Poisoning In Livestock, J Craig

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

LIVESTOCK need a plentiful supply of good, fresh drinking water for normal health and high production.

Over large areas of Western Australia the water from bores, springs and wells contains varying but appreciable amounts of salt and special care may be needed to ensure that the stock water supply is satisfactory.

Hints On Irrigating Citrus With Saline Water, Stanley Thomas Smith

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

IN the past few years a number of citrus orchards near Perth have shown signs of damage caused by excess "salt" (chloride) uptake. All have been irrigated either from the Canning River or from private bores or dams.

Senior Soil Research Officer S. T. Smith describes glasshouse experiments which have given some useful guides to minimising "salt" damage in citrus trees irrigated with low-quality water.

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

A Practical Guide To Building Contour Banks With A Road Grader, J E. Watson

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

THOUSANDS of miles of contour banks have been built in Western Australia, and most of this earthmoving has been done by tractor and disc plough* or by road grader.

This article describes the technique recommended for bank construction with the road grader.

Agriculture In Western Australia. 2. A Preview Of Future Development, A W. Hogstrom

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

THE agricultural areas of Western Australia produce most of the State's agricultural output.

Only isolated small areas of arable agriculture exist in the North- West and tropical areas of the State.

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.

Firebreaks Without Erosion : Hints To Prevent Firebreak Erosion, Department Of Agriculture, Western Australia

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

AGRICULTURAL fire risks are now greater than they have been in the past and are steadily increasing with the advance of agriculture in Western Australia.

During the past 20 years the area of cleared arable land and the area under crop have more than doubled.

The area of established pasture is four times as great as it was. Pastures and crops are much more productive —and more liable to carry destructive fires than they were.

A Progress Report On Commercial Cotton Growing On The Ord River Project, William John Toms

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

The recommendations given in this article have been built up from the experience of the author in growing 200 acres of cotton in the Ord River area during the 1962-63 season for the Department of Agriculture, from findings made by Kimberley Research Station, and from discussions with the present farmers in the area.

When a new form of agriculture is introduced into a new area techniques and ideas change rapidly as farmers become acquainted with their new environment and the new crops. The recommendations will therefore require constant revision.

Development Of Water Quality Criteria For Aquatic Life, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

It is now recognized that water pollution is an important problem, that it becomes more widespread and serious as population and industry expand, and that something must be done if aquatic life resource are to be saved and their productivity maintained. In the past there has been a great deal of uncertainty in approaching this situation and a general lack of understanding of the details and ramification of the overall problem. In the efforts for the abatement of pollution, only a few clearcut objectives have been established. Knowledge is lacking as to what the objectives should be. There is still …

Concluding Remarks Of Appreciation With Comments On Histoplasmosis And Cryptococcosis, Philip J. Spear

Vertebrate Pest Conference Proceedings: 1st (1962)

The record of this meeting will stand as a permanent tribute to Dr. Walter Howard and his associates. It should remind them for years to come of their worthwhile contribution in conceiving, organizing, promoting, and handling the details of this first Vertebrate Pest Control Conference. Those of us privileged to attend will be grateful for the opportunity to enlarge our acquain¬tance with the workers in the vertebrate pest control field, and to share in this exchange of information. The National Pest Control Association, whose members provide among other services, control of many vertebrate pests, draw information and guidance from many …

Infectious Disease Hazards To Pest Control Operators, Paul Arnstein Dvm, Mph

Vertebrate Pest Conference Proceedings: 1st (1962)

One of the primary reasons for controlling most vertebrate pests is the role these creatures play as links in the infection chain of certain agents pathogenic to man. It is reasonable to assume that the persons engaged in the eradication or removal of pests are at some risk of contacting zoonoses - diseases transmissible from animals to man. Unfortunately, histories or epidemiological data of occupational infections among pest control operators are not available; perhaps this society may become a future assembly point for statistics in this field. The hazards therefore have to be approached theoretically: diseases known to be associated …

Meeting The Meadow Mouse Menace, William D. Fitzwater

Vertebrate Pest Conference Proceedings: 1st (1962)

The orchardist has many ways to lose money but one of the best is to ignore his mouse problem. This apparently insignificant, short-tailed little rodent by his unobtrusive but systematic attacks on the growing tissue of trees can be very expensive. The Indiana Extension Horticulturist has stated that mice are the number one cause for orchardists going out of business in recent years in that State. Moreover, the problem is not a recent one as a questionnaire to county agricultural agents in 1924 (Davis, 1925) showed that field mice were even then considered a problem in 40 per cent of …

Mole And Woodrat Control, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 1st (1962)

MOLES: In regions where moles thrive, lawns in golf courses, parks, cemeteries and home yards are often made unsightly by dirt mounds and ridges pushed up by the active little animals. In cultivated land, moles may cause consider¬able economic loss through their burrowings. Mole control can be divided into six basic categories: exclusion, repellents, gases, toxic baits, reduction of food supply, and trapping. Un¬changed over the years, trapping is still considered the most reliable of all methods of control, however, under certain conditions or situations, the other methods of control may be extremely useful. WOOD RATS: The native wood rat …
