Light Lands In Western Australia. 3. Microbiological Problems In The Establishment Of Legumes On Light Lands, C A. Parker

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

EXPERIENCE has shown that the establishment of leguminous pastures is essential for successful economic development of Western Australian light lands.

Subterranean clover is the preferred legume in most light land areas, with lupins holding an important place in the more northerly districts, and on the deeper sands.

Mycotic Dermatitis (Lumpy Wool) And Fleece Rot Of Sheep, J Shilkin

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

Matted and sometimes discoloured specimens of wool are often received at the Department of Agriculture during seasons of heavy rainfall.

Two similar but quite distinct diseases are recognised as having caused this condition.

They are mycotic dermatitis (lumpy wool) and fleece rot. Both conditions damage the fleece and render affected sheep susceptible to blowfly strike.

Detergents For The Dairy Farm, H Maslin

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

CLEANLINESS in both the physical and bacteriological sense is essential to the production of high quality dairy products, and high quality in these products is essential to both the health of the community and the successful and economic operation of the industry.

Detergents have an important place in maintaining dairy hygiene—but they must be properly used if they are to be really effective.

In this article Dairy Instructor H. Maslin, M.D.D., describes the qualities of a good dairy detergent and explains how it should be fitted into the regular cleaning routine.

Cleansers For The Milking Machine, Department Of Agriculture, Western Australia

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

WITH the opening of the flush season dairy farmers should make sure milking machines are working at maximum efficiency.

Machines not working efficiently can cause production losses and damage to cows as well as wasting farmers' time.

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.

Preliminary Report: Monolayer Behavior Studies, 1959, Bureau Of Reclamation

Publications (WR)

During the fall of 1959, monolayer behavior studies were made on two lakes in the southwest; Boulder Basin of Lake Mead, Nevada, and Lake Sahuaro near Phoenix, Arizona. These studies were made to evaluate the effect of geographical and climatological conditions on movement and behavior of monolayers. The Lake Sahuaro tests also were used to provide data for design and development of improved methods of application and maintenance of a film on this lake in anticipation of full scale, evaporation-reduction tests to be performed there during the summer of I960. The Lake Mead studies produced the following general points of …

The Use Of Seed Inoculum For Subterranean Clover In The Jerramungup, Gairdner River Areas, William John Toms

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

IT is unlikely that benefits will be obtained from inoculating Dwalganup or Bacchus Marsh subterranean clover seed sown in the Jerramungup or Gairdner River districts other than on the fine sands of different geological origin (Miocene) occurring in some southern areas of the Gairdner River District.

Studies On The Microcrustacea Of Three Montane Lakes In Glacier National Park, Montana, Robert O. Megard

Biology ETDs

Grinnell Lake, Lake Josephine, and Swiftcurrent Lake, at an elevation of approximately 5,000 feet in northwestern Montana, are comparable with lakes in the montane zone defined by Pennak for lakes at elevations between 8,200 feet and 10,500 feet in the Rocky Mountains of northern Colorado. Five species of Copepoda, six Cladocera, and four Ostracoda were collected in the lakes studied. The population of microcrustacea in these lakes was most dense in or slightly above the masses of rooted aquatic vegetation growing to a height of six to 10 inches above the bottom wherever the water was between three feet and …

Microorganisms And Soil Structure, T. M. Mccalla

Department of Agronomy and Horticulture: Faculty Publications

SUMMARY

Laboratory tests were made to determine the effectiveness of different compounds and microbial groups in increasing the stability of Peorian loess lumps against the action of falling water drops. The influence of these on percolation tests in the laboratory was also determined.

Many organic substances-dextrose, sucrose, starch, peptone, cullulose, and gum arabic-did not themselves contribute directly to soil-structure stability, though these substances do furnish energy material for soil microorganisms, which can convert them readily into either microbial tissue or decomposition products that increase soil-structure stability. Lignin, proteins, oils, fats, waxes, resin, and paraffin increased the stability of lumps of …

Distribution Of Microorganisms In The Soil As Affected By Plowing And Subtilling Crop Residues, Roy C. Dawson, Virginia T. Dawson, T. M. Mccalla

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The purpose of this investigation was primarily to determine what effects rate and method of application of residues have on the distribution of microorganisms within the plow-depth layer of soil.

Studies On Restaurant Sanitation And The Effect Of Sodium Azide On The Physiology Of Streptococcus Salivarius, Kenneth D. Rose

Open Access Master's Theses (through 2010)

Whether restaurant eating utensils serve as vectors in the transmission of respiratory and related diseases is still a matter for question, in spite of the overwhelming evidence in support of this contention.This is due to largely to the lack of epidemiological evidence, the tracing of an outbreak of a disease directly and unquestionably to contaminated eating utensils.The very nature of the vectors concerned obviates any possibility of obtaining this epidemiological evidence, since the contaminating agent exists as such only momentarily at the best. This research problem was undertaken with the hope that a technique designed to demonstrate the appearance of …

The Geographic Distribution Of Azotobacter And Rhizobium Meliloti In Nebraska Soils In Relation To Certain Environmental Factors, H. B. Peterson, T. H. Goodding

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In this investigation a survey of Nebraska soils has been made in order to determine the distribution of the aerobic nonsymbiotic and symbiotic nitrogen fixers of the genera Azotobacter and Rhizobium respectively. In connection with this survey, some of the characteristics of the soils which may bring about this distribution were studied. Up to this time practically no research has been reported on the microflora of the soils of Nebraska. Hence there is little basis for predicting the activity of these organisms under environmental conditions as they exist here. It is hoped that this work will not only supply some …

Two Lincoln (Nebraska) Typhoid Fever Epidemics Of 1911 And 1912., Herbert H. Waite

School of Biological Sciences: Faculty Publications

On August 29, 1912, I was requested by the Board of Health of the city of Lincoln to make an investigation to determine if possible the origin and cause of an outbreak of a disease reported as typhoid fever which was then prevailing. This outbreak was said to be most prevalent in one particular portion of the city and consequently attention was turned to that portion. Of the cases reported an investigation was made of over 60 individuals and after considering all the probable causes for the majority of those affected the conclusion was reached that all could be logically …

Sanitation Of Drinking Water, Kentucky Library Research Collections

Research Collections

The Arena was an American literary and political magazine founded by journalist, Benjamin Flower. Flower wanted the magazine to "agitate, educate, organize," he used investigative techniques to obtain information to bring about social, economic and political reform. This article focuses on the contamination of drinking water and its role in spreading diseases.
