Contour Cultivation : Cheap Erosion Control, T R. Negus, B. Barrett

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

Although the benefits of contour cultivation are well recognised, it makes cultivation more difficult, particularly if the paddock is split by contour banks and grassed waterways. However, a comparison east of Pingelly indicates that contour cultivation is little more expensive or time-consuming than ordinary cultivation.

Plant Succession Studies On Subalpine Acid Mine Spoils In The Beartooth Mountains, Patricia Lea Howard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Large areas within alpine and subalpine tundra have been by disturbed by mining during this century. The most promising method for retarding deterioration of these areas is revegetation with native species through both seeding and transplants. One natural process of revegetation which occurs on portions of many existing disturbances seems to be the establishment of a few species that expand with time to form matts of plants.

At the McLaren Mine, located at 3000 m elevation in the Beartooth Mountains, Montana, active succession is occurring and is dominated by Carex species. Seed viability and successional patterns studies were conducted on …

Soil And Plant Analysis : A Guide To Fertilizer Usage, Walter Jacob Cox

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

Soil and plant analysis can be used to identify problems in soils, diagnose nutrient deficiencies and as a guide to fertiliser usage.

Soil testing is particularily useful where large amounts of phosphorus and potassium are leached or removed from the paddock in hay or silage.

Actual rates of fertiliser can only be recommended from soil testing and only in conjunction with additional biological and economic information.

Bulletin No 4007 - Grasses In South Western Australia, J G. Paterson

Bulletins 4000 -

IThe grasses comprise one of the world's largest families of flowering plants, with over 500 groups or genera containing well over 5000 individual types or species distributed throughout the world. About 125 groups have been recorded in Western Australia but it is probable that the list is far from complete. About one third of these have ° been introduced from overseas.

The purpose of this bulletin is to describe those grasses which are more commonly found in the south-west of Western Australia. Also, as many people are interested in knowing the name and nature of a grass when they find …

The European Wasp : A New Threat To W.A, Department Of Agriculture, Western Australia

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

The European wasp was detected in Western australia for the first time in January and February 1977 in the metropolitan suburbs of Mosman Park, Cottesloe and Attadale.

So far it has only been found within an area of 8 km radius from Fremantle but the outer boundries of the infestation are still uncertain.

It is Department of agriculture policy to eradicate the European wasp, if possible, and to destroy all nests detected.

Cost Of Farm Water Supplies : Conclusions From Surveys, I A F Laing

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

The Department of Agriculture, in conjunction with the Farm Water Supply Advisory Committee, has conducted farm wster supply surveys in many districts in the wheatbelt.

The aim of the surveys was to collect data to assess the existing water supplies, the potential for further water supply developments and to compare the relative difficulty of water supply development in different localities.

Economics Of Farm Water Supplies, P P. Eckersley

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

The economics of farm water supplies can be studied in two ways. One is to compare the costs of alternative ways of supplying a specified quantity of water to a farm. Another is to calcu;ate how mucha farmer can afford or will pay for a water supply.

I propose to look at these questions from the point of vieew of an eastern wheatbelt farmer, assuming that he must pay the full costs of any water supply provided for his property.

Comparison Of Economic Returns From Grain Crops, H M. Fisher

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

While wheat is still generally the most profitable crop in Western Australia the relative profitability of barley and linseed has risen in the last few years; in southern areas they are likely to be at least as profitable as wheat.

Oats has fallen in profitability relative to wheat, and grain legumes have suffered a marked fall. Yields of these grains have increased with the introduction of new varieties but their price increases have not kept pace with those of wheat and barley. The present relationship of yields and costs indicates that substantial price changes will be needed to change the …

Composition Of Arkansas Grapes During Maturation, Cameron Jones, Dominic T.C. Yang, Thomas O. Whitley

Journal of the Arkansas Academy of Science

Changes in organic acid and glucose content during maturation and ripening of grapes grown in Arkansas in 1973 are shown for four French hybrid varieties, S5279, S10878, SV23- 657, and S13053, and for four rotundifolia varieties, Scuppernong, Tarheel, Fry, and Magoon. In all varieties the concentrations of malates and tartrates were highest in the early stages of berry growth after veraison. During ripening the titratable acidity decreased and Balling and pH measurements increased. Although varieties reached maturity on different dates, changes in parameters followed similar curves typical for grapes of the species but occurring over a short period (Johnson and …

Facility Costs Of Centralized Grain Storage Systems Utilizing Computer Design, Otto J. Loewer Jr., Thomas C. Bridges, Douglas G. Overhults

Biosystems and Agricultural Engineering Faculty Publications

The item considered most often when estimating the cost of a grain storage facility is capacity. Of equal or greater importance is daily harvest rate. Other important considerations include drying method, materials handling equipment, energy cost, facility arrangement, labor requirements, grain quality and management ability. Only through a comparison of facilities which offer similar capacity, capability and convenience can the purchaser obtain his best system.

A Comparison Of Hay Conservation Systems, E E. Rowley

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

The high cost an dshortage of farm labour in the Esperance District is posing serious problems for farmers using traditional hay conservation systems. Author Ted Rowley, then an advisor with the Esperance District office of the Department of Agriculture surveyed a number of farms to study the economics of varoius alternatives. This article is a summary of his report presented to a 1976 Fodder Conservation Workshop.

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Within the past decade, emphasis has been placed on the quality of our environment. Beef cattle feedlots have been singled out as a significant source of environmental pollution. Environmental protection provided by control facilities requires basic knowledge of the physical and chemical properties of feedlot runoff. This bulletin summarizes studies of physical and chemical properties of beef cattle feedlot runoff completed from August, 1968 through December, 1972.

Trials With Trickle Irrigation Equipment At Morogoro Preliminary Report, M.E. Parkes, M. E. Madata

Tanzania Journal of Science

The use of trickle irrigation is discussed with reference to Tanzania. A split-split plot design experiment is described in which yields of tomato, onion, and cabbage are compared for trickle and hand-irrigated plots, with different levels of fertiliser treatment. Yields for trickle-irrigated plots were significantly greater only for tomatoes. These results were achieved during July to October and a second attempt to grow the same vegetables during December to March was unsuccessful. Further trials are required to obtain a suitable rotation of vegetable crops from both a nutritional and agronomic point of view. Experience with the trickle irrigation equipment is …

Decide : How Much Superphosphate, G A. Robertson, J. W. Bowden, N. J. Halse

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

* A 400 per cent increase in ihe price of superphosphate has reduced the economic optimum rates of super for crops and pastures in 1975.

* Many factors, both biological and economic, must be taken into account in determining the rate of superphosphate to apply.

• DECIDE, a model developed by CSIRO and the Department of Agriculture, provides a formal system in which all these factors can be considered.

• DECIDE is based on the results of all research on superphosphate carried out in Western Australia. However, each farmer's own knowledge of his farm, the soils, crops and animals is …

Water Economy For Lawns And Gardens, K S. Cole

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

Much of the summer water consumption occurs because it is widely believed that heavy summer watering is necessary. Householders often mistakenly water heavily to keep their gardens green and growing. Many may not realise that gardens can be kept vigorous and healthy with much less water than is commonly applied.

Land Systems Of The Brockman River Catchments, S. Porritt

Natural resources published reports

The survey was conducted to gain basic information about the agricultural land use of the Brockman River Catchment. The University of Western Australia Faculty of Agriculture was interested in the area as a compact, agriculturally diverse area close to Perth which was, therefore, suitable for filed studies. The Department of Agriculture, Moora Office was interested in this study as a framework within which to improve its extension services in the area.

Both parties cooperated in investigations of the area by providing data and equipment. Field work was carried out in summer 1973-74 and data compiled by an agricultural science student …

A Comparison Of Consumer's Surplus And Monopoly Revenue Estimates Of Recreational Value For Two Utah Waterfowl Marshes, C. Holden Brink

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Demand curves were estimated for waterfowl hunting and nonconsumptive recreational use from use rate and variable expenditure data collected at the Bear River Migratory Bird Refuge and the Farmington Bay Waterfowl Management Area during fiscal 1969. Consumer's surplus and monopoly revenue estimates were then derived from the demand functions. Adjusted estimates of consumer's surplus for waterfowl hunting amounted to $7,260 per year at Bear River and $11,400 per year at Farmington Bay. For nonconsumptive recreation annual consumer's surplus was estimated to be $18,700 at Bear River and $3,760 at Farmington Bay. Monopoly revenue estimates were between one-half and one-fourth the …

Bulletin No 3867 - Water For Agriculture. Clearing Cloudy Or Coloured Water, N. E. Platell

Bulletins - 3000 - 3999

THE suspended material in most water supplies is generally clay, although sometimes organic matter and materials precipitated from solution, such as hydrated iron oxides, may be present. Coloured waters are those waters that are still coloured, due to dissolved coloured matter, after suspended material has been removed. Some coloured waters such as those found in swampy areas may be entirely free of suspended material.

The amount of clay or colour present is mainly of concern where the water is used for household purposes. Only rarely is the clay or colour present in such quantities that the water is undrinkable for …

KWRRI Research Reports

The institutions responsible for water resources management in the United States have originated as political responses to major social issues. Each agency institutionalized a procedure for structuring and comparing alternatives in the formulation of its total program. Each agency originally sought to promote effective resolution of its social issue (flood control, development of arid lands, soil erosion, etc.), but more recent efforts have sought better coordination among agency practices through a common procedure largely derived from economic theory. Any procedure, however, varies in application with the interpretation and judgment of individual planners. Today, public pressures have brought political directives requiring …

Dust Storms Cause Yield Losses, Department Of Agriculture, Western Australia, C. H. Trotman

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

Farmers and research workers are well aware that heavy grazing during summer loosens and exposes soil to the action of strong winds and summer thunder storms. They also realise that dust storms mean soil loss from paddocks, but until now there has been little idea of the effect of these storms on crop yields in subsequent seasons.
