ONE of the major problems associated with an intensive piggery is the disposal of the effluent; the nearer the piggery is to urban areas, the greater the problem.

Weed Control In Irrigation Channels, Geoffrey A. Pearce

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

Probably the major task involved in maintaining drainage and irrigation channels is the regular removal of weed growth.

The cost of hand chipping a standard head channel is approximately 10s. per chain.

The use of suitable chemicals could reduce this cost considerably.

The Levy Nest : A Useful Aid To Farrowing, P Mcnamara

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

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 Cooling Towers : For Cooling Milk On The Dairy Farm, K Needham

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

Experience on dairy farms where water cooling towers have been installed has shown that the quality and grading of milk and cream has been improved and maintained, particularly during the summer.

MOST defects in the quality of dairy produce can be attributed to the activity of micro-organisms which cause spoilage.

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.

A Power Sampler Of Undisturbed Soils, Wesley F. Buchele

Wesley F. Buchele

An undisturbed column of soil is required to measure the physical properties of soil and the distribution of roots, insects, and fertilizer within the soil. Because of the excessive ex­pense of digging a trench around an undisturbed soil column, research on the physical properties et cetera of soil in the undisturbed state has been limit­ed.

Design And Operation Of The Msu Tandem Tractor, Wesley F. Buchele

Wesley F. Buchele

A tandem tractor composed of two tractors hooked together and con­trolled from the rear tractor has been built at the Agricultural Engineering Department, Michigan State University. It was tested on sod, plowed, and plowed and disked land. Results indi­cate that the tandem tractor can pro­vide the farmer with a versatile power unit: one four-wheel drive tractor for pulling heavy loads; and two two-wheel drive tractors for pulling light loads.

Development Of A Recording Volumetric Transducer For Studying Effects Of Soil Parameters On Compaction, J. D. Hovanesian, Wesley F. Buchele

Wesley F. Buchele

Increased research effort has been directed toward the solution of soil compaction problems in the past few years. Research workers dealing with these problems have been handicapped for at least the following four reasons: 1 Lack of definition and understand­ing of soil stress and soil compaction; a need for a suitable mathematical model 2 Lack of suitable recording equip­ment for measuring changes in soil physical phenomena, particularly soil compaction 3 Lack of basic engineering infor­mation about the mechanics of agri­cultural soils 4 Lack of adequate information showing the effect of certain parameters (soil moisture, soil type, and others) upon soil …

Application Of Continuum Mechanics To Soil Compaction, G. E. Vandenberg, Wesley F. Buchele, L. E. Malvern

Wesley F. Buchele

To study the soil compaction prob­lem, the amount of compaction change at every point in the soil resulting from loads applied to the surface must be de­termined. If this change can be calculated, the effects obtained from varying the loads can be observed and thereby information gained which will permit predicting and possibly controlling compaction. Such cal­culations require a suitable theory of soil mechanics to formulate a mathematical model describing the soil.

B521: Containers For Shipping Apples, Homer C. Woodward

Bulletins

Studies since 1946 affirm that the major causes of apple bruising in Maine are the methods used in packing the containers, layer materials, and handling. During the past two years, the emphasis of the studies has been testing of different containers and packing materials to determine which give the apples the best protection. Those who pack apples have become increasingly conscious of the higher costs involved. Therefore, the cost of the various containers and packaging materials also was studied. Thus, the overall objective of the study was to determine what type(s) of container or containers and materials give the best …

Aircraft In Agriculture, N. E. Shafer, J. D. Furrer, J. W. Lomax

Nebraska Agricultural Experiment Station: Historical Circulars

Airplanes were first used in agriculture shortly after the close of World War I. They proved valuable for locating mosquito breeding areas, for forest fire patrol work, as an aid in locating outlaw cotton fields in the campaign against pink bollworm, and for surveying damage caused in large forested areas by the spruce budworm.

The Use Of A Small Electric Motor In Silo Filling, E. E. Brackett, E. B. Lewis

Nebraska Agricultural Experiment Station: Historical Circulars

Filling a silo 30 feet or more in height with a motor as small as five horsepower has been looked upon in general by Nebraska farmers as an impractical, if not impossible, procedure. The practice is not unheard of in other states, and certainly the possibility of avoiding the large tractor-driven cutters and the large crews will be welcomed by those who have available service from power lines.

The Nebraska Tractor Law And Rules For Official Tractor Tests, O. W. Sjogren, E. E. Brackett, C. W. Smith, F. R. Nohavec

Nebraska Agricultural Experiment Station: Historical Circulars

The Nebraska Tractor Law, which became effective July 15, 1919, was enacted to encourage the manufacture and sale of improved types of tractors and to contribute to a more successful use of the tractor for farming. It was thought that the best method of accomplishing these objects would be to require a tractor of each model sold in the State to be tested at the State University and to have the results of these tests made public.

The Nebraska Tractor Law And Rules For Official Tractor Tests, L. W. Chase, E. E. Brackett, O. W. Sjogren, C. K. Shedd

Nebraska Agricultural Experiment Station: Historical Circulars

The Nebraska Tractor Law, which became effective July 15, 1919, was enacted to encourage the manufacture and sale of improved types of tractors and to contribute to a more successful use of the tractor for farming. It was thought that the best method of accomplishing these objects would be to require a tractor of each model sold in the State to be tested at the State University and to have the results of these tests made public. These tests will give reliable information on the power, capacity and fuel consumption of each tractor and also some information on endurance. The …

Measuring Silage And Capacity Of Silos, L. W. Chase

Nebraska Agricultural Experiment Station: Historical Circulars

The condition of the corn at filling time, the rate of filling, and the length of time settling has taken place before measuring the depth of the silage, all tend to cause variations in the weight per cubic foot of the silage and in the tonnage that can be placed in a silo. The greatest variation comes when very green corn or very ripe corn is used, and because of this it is possible that a cubic foot of green silage, which may weigh fifty pounds, holds no more dry matter than a cubic foot of overripe silage which weighs …
