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?

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.

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. 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.

Reports
This report reviews activities on this project since the Progress Report, Part IV, June 1961.
The summer of 1961 has been one of the driest on record for Ogden Bay and Howard Slough Refuge. The extreme shortage of irrigation water has resulted in very little flow in the Howard Slough which originates from return flow. The available water from the Weber River for the Ogden Bay Refuge was also the lowest on record. The scarcity of water at these two refuges has resulted in increased salinity.
Most of the routine work on the project during the summer was done by …
Shellfish Resources Of Washington, Robert Grant Levens
Shellfish Resources Of Washington, Robert Grant Levens
Graduate Student Research Papers
This paper will explore the salt water shellfish resources of Washington State. Particular emphasis will be placed upon the Pacific and Olympia Oysters, the Dungeness Crab, the research being done at Quilcene, and the lesser varieties of shellfish, including shrimp and the hardshell species of clams. The latter includes the littleneck, butter, Manila, and geoduc clams. A major emphasis will be the commercial importance of the shellfish, but the sportsman and the expanding role of Washington as a summer recreation area will not be overlooked.

The Effects Of Certain Environmental And Biological Factors On Rally Calling In The Chukar Partridge, H. Warrington Williams
The Effects Of Certain Environmental And Biological Factors On Rally Calling In The Chukar Partridge, H. Warrington Williams
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Naturalists for many years have known that birds sing most at dawn and at dusk, but to which of many physical variables they are responding has not been completely determined. This problem has taken on importance in the field of wildlife management because calling rate has been used as an index of abundance for numerous game birds, namely the Pheasant, Phasianus colchicus (Kimball, 1949); the Mourning Dove, Zenaidura macroura (McClure, 1939); the Bobwhite Quail, Colinus virginianus (Bennitt, 1951; Rosene, 1957): and the Woodcock, Philohela minor (Pitelka, 1943).
Extension Of The Range Of Northern Pike (Esox Lucius), D. B. Mccarraher
Extension Of The Range Of Northern Pike (Esox Lucius), D. B. Mccarraher
Nebraska Game and Parks Commission: Staff Research Publications
Recent technical publications and popular literature have not fully established the present geographical range of the northern pike. A survey by the writer in 1955 showed that 26 states and Canadian provinces had resident northern pike populations. During the past 5 years pike have been introduced into several other states, thus extending the range. Pike are already established in most of the northern states and are now being released into waters of the south and west.
Water For Man, Sterling A. Taylor
Water For Man, Sterling A. Taylor
Faculty Honor Lectures
Man's uses for water are rapidly increasing. His demands and needs for water for his personal use and for cleanliness, recreation, industry, and food production are increasing as the population and standard of living rise. At the same time, his knowledge of the behavior and nature of water is increasing.
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
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.

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.

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.
