Salt Land Survey, 1962 : Report Of A Survey Of Soil Salinity In The Agricultural Areas Of Western Australia, L C. Lightfoot, S. T. Smith, C. V. Malcolm

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

IN Western Australia there are within the agricultural areas about one million acres of salt land, largely within the 14-25 inch rainfall area used for cereal and wool production.

In March, 1962, farmers in 68 shires in the agricultural areas of Western Australia estimated that on their properties 305,270 acres of land previously cropped or sown to pasture had become salt affected. Of this total, 59,203 acres had gone salt in the seven years immediately before the survey.

Agriculture In The Lakes District : Report Of A Survey Of Farm Practices, A W. Hogstrom

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

At the request of the Central South Zone Development Committee a survey which covered 58 farms in the Lakes District was carried out by officers of the Department of Agriculture. Field work for the survey started in 1961.

The Lakes District supports about 70 holdings adjoining a chain of salt lakes to the east of Newdegate and Hyden but west of the No. 1 Rabbit Proof Fence.

The chain of lakes is about 70 miles long running in a N.N.W. to S.S.E. direction. The lakes are O'Connor, Carmody, Hurlstone, Varley, Gulson, Fox, Camm, King, and Pal lamp.

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.

The Development Of Irrigation In Nebraska, 1854–1910: A Descriptive Survey, Martin Evald Carlson

Department of History: Dissertations, Theses, and Student Research

Preface (excerpted)

The primary purpose of this study is tto trace the development of irrigation in Nebraska from the organization of the state as a territory in 1854 through the rest of the nineteenth century. This period covers the first four stages through which irrigation progressed: individualistic, corporate, district, and state. A brief discussion of the North Platte Project is included, however, in order to carry the story into the fifth and final stage--the development of irrigation with Federal aid, as provided for in the Reclamation Act of 1902.

The emphasis of this work is on the irrigation movement and …

Fisheries Report Ii (2) - Preliminary Report On The Effectiveness Of Escape-Gaps In Crayfish-Pots, B. K. Bowen

Fisheries Research Reports

The Western Australian commercial crayfish, Panulinrus cy,nus George, (1962)", is caught in depths ranging from a few feet to approximately 45 fathoms. In the shallow waters large numbers of crayfish measuring, less than the legal minimum length are brought to the surface in the standard commercial crayfish pots. The law requires that these undersize crayfish be returned to the sea, but there is always the temptation to retain them for illegal sale. In addition, the undersize crayfish which are returned to the sea are often damaged by handling. The probability is that their mortality rate is higher than those which …

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.

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.

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.

Water For Agriculture. 6. Control Of Algae In Water Supplies, R C. Gorman

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

ALGAE are primitive forms of plant life that are common and normal in surface waters. They are fonnd in every water supply exposed to sunlight.

Their presence is not normally detectable until there are enough of them to make their presence obvious.

The Archeology Of The Lime Creek Site In Southwestern Nebraska, E. Mott Davis

University of Nebraska State Museum: Staff and Affiliates, Publications

The Lime Creek site is a stratified Early Lithic (Paleo-Indian) camp site buried in the Terrace-2A alluvial fill of a valley in the dissected loess plains. Geological correlations indicate an early Valders (Wisconsin- IV) date. A radiocarbon date (No. C-471) of 9524 B.P. from just below Lime Creek I, the lowest occupation zone, must be taken only as a minimal possible age for the site. The animal bones in Lime Creek I are primarily of pronghorn and beaver, whereas those in Lime Creek III, the highest occupation zone, are exclusively of bison. The change in hunting patterns seems due to …

Interbasin Movement Of Ground Water At The Nevada Test Site, Isaac J. Winograd

Publications (WR)

The present paper presents hydraulic evidence for the interbasin circulation of ground water through carbonate rocks of Paleozoic age at the Nevada Test Site. An integral part of this evidence is the discovery that aquifers in alluvium and tuff, formerly thought to be the principal aquifers at the Test Site, are semiperched above a thick tuffaceous aquiclude that separates them from the carbonate rocks.

This paper is based on one of the studies being made by the Geological
/="/">Survey for the Atomic Energy Commission. These studies seek to evaluate
/="/">the risk that may arise if ground water should …

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

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.

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. 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.
