Bulletin No. 105 - Factors Influencing Evaporation And Transpiration, John A. Widtsoe Aug 1909

Bulletin No. 105 - Factors Influencing Evaporation And Transpiration, John A. Widtsoe

UAES Bulletins

The irrigation investigations conducted by the Utah Experiment Station, some of the results of which form this *report, were undertaken for the purpose of adding to our knowledge of the natural laws upon which the art of irrigation may be safely built. The work has had for its dirrect object the study of the mutual relations of plants, soils and water, as these relations may indicate the most economic use of water for plant production. In pursuit of the investigations it became necessary not only to follow the movement of water in soils under irrigation conditions, but to determine also …


Bulletin No. 104 - The Storage Of Winter Precipitation In Soils, John A. Widtsoe Oct 1908

Bulletin No. 104 - The Storage Of Winter Precipitation In Soils, John A. Widtsoe

UAES Bulletins

It has been found that the production of one pound of dry plant substance on soils of average fertility, requires in humid districts not more than five hundred pounds of water, and in arid districts like Utah about seven hundred and fifty pounds. This indicates that the average rainfall of Utah, which is about twelve inches, if properly conserved in the soil, is sufficient to produce annually, without irrigation, from thirty to forty-five bushels of wheat to the acre, or corresponding yields of other crops. The realization of this truth has changed greatly our views of irrigation practices. The beginning …


Bulletin No. 103 - Milling Qualities Of Meat, Robert Stewart, Joseph E. Greaves Apr 1908

Bulletin No. 103 - Milling Qualities Of Meat, Robert Stewart, Joseph E. Greaves

UAES Bulletins

Investigations regarding the chemical and milling characteristics of some of the various varieties of wheat grown in the State have been carried on since the season of 1904. This is, however, the first report of the investigations that has been published. The work was started with the hope of assisting in the determination of the varieties of wheat best adapted to the State. While, of course, the variety which does not yield well but which has excellent chemical and milling characteristics is not desirable, yet on the other hand, as has already been so often pointed out, neither is the …

Bulletin No. 97 - Report On The Southern Utah Experiment Station, R. S. Northrop, Joseph T. Atkin, P. A. Yoder

UAES Bulletins

When, in the early part of the year 1905 , the management of the Southern Utah Experiment Farm was turned over to the officials of the Utah Agricultural Experiment Station, in compliance with an act of the legislature of that year a number of experiments were under way, principally variety tests with orchard and small fruit. The State Board of Horticulture had been in charge of this farm since its establishment in 1899, and had succeeded in making out of it not only a place that will indicate the varieties of fruits adapted to that climate and soil , but …


Bulletin No. 101 - Feeding Experiments With Cattle, Sheep, Swine And Horses, R. W. Clark Dec 1906

Bulletin No. 101 - Feeding Experiments With Cattle, Sheep, Swine And Horses, R. W. Clark

UAES Bulletins

Since the establishment of sugar factories in this State, considerable inquiry has arisen regarding the food value of sugar beets and the by-products of the factories. The last publication from this station on the subject was Bulletin No. 90 which gave the results of feeding sugar beet pulp and molasses in various combinations to sheep and steers. Previous to the appearing of this publication some experimental work had been carried out in feeding sugar beets to swine and sugar beet pulp and beet molasses to sheep. The results secured seemed to warrant further work in the same direction and in …


Bulletin No. 100 - Arid Farming Investigations, W. M. Jardine Dec 1906

Bulletin No. 100 - Arid Farming Investigations, W. M. Jardine

UAES Bulletins

The Utah Legislature of 1903 passed a bill providing for the investigation by the Experiment Station of dry-land farming problems in the State of Utah, and appropriating $12,500 to be expended in carrying on this work during the two years, 1903 and 1904. Six experimental dry farms were located one in each of the following counties: Iron, Juab, San Juan, Sevier, Tooele and Washington. A second appropriation of $15,500 was made by the Legislature of 1905, for the purpose of continuing, the investigations.


Bulletin No. 99 - Report On Irrigation And Drainage Investigations During 1905-1906, E. R. Morgan, W. W. Mclaughlin Dec 1906

Bulletin No. 99 - Report On Irrigation And Drainage Investigations During 1905-1906, E. R. Morgan, W. W. Mclaughlin

UAES Bulletins

A general plan for the scientific investigation of the laws governing plant production as influenced by the application of irrigation water, was outlined in 1900 by Dr. John A. Widtsoe as Director of the Utah Experiment Station. The detailed plans were prepared by the heads of the Chemical, Agronomy and Irrigation Department, under whose cooperation the work was to be carried on. In 1903 the Office of Experiment Stations of the U. S. Department of Agriculture, by contributing funds to this work, became a party to the experiments. Since then the investigations have been under the joint supervision of the …


Bulletin No. 95 - Codling Moth Work In 1904: The Relative Value Of Early And Late Sprays, E. D. Ball, E. G. Peterson Mar 1906

Bulletin No. 95 - Codling Moth Work In 1904: The Relative Value Of Early And Late Sprays, E. D. Ball, E. G. Peterson

UAES Bulletins

The codling moth continues to be the most s serious pest of the Utah horticulturist and was therefore made the main subject of investigation by the Entomological Department for the season of 1904.

In spite of the immense amount of work that ha been done on this subject by various entomologists in this and other countries, several vital points still remain unknown and many more that have been worked out for other localities must be verified and adapted to our conditions.

Circular No. 4 - Memoranda Of Plans Of Irrigation Investigations

UAES Circulars

The present series of irrigation investigations was begun in 1901, and has been continued since then. Since January 1st, 1904, the investigations have been carried on in co-operation with the Irrigation Investigations (Chief, Professor Elwood Mead) of the Office of Experiment Stations, U.S. Department of Agriculture.


Bulletin No. 91 - Arid Farming In Utah: First Report Of The State Experimental Arid Farms, John A. Widtsoe, Lewis A. Merrill Jan 1905

Bulletin No. 91 - Arid Farming In Utah: First Report Of The State Experimental Arid Farms, John A. Widtsoe, Lewis A. Merrill

UAES Bulletins

The present high position of Utah among the great commonwealths is due to the practice of irrigation. According to the last census, about 983 square miles are now being irrigated; and yet only a small fraction of Utah's water supply is used for purposes of irrigation. With the adoption of improved methods of using water, and the construction of mighty reservoirs to store the floods of spring, the irrigated area in this State will be largely increased. It is not at all improbable that in time the water supply may be made to irrigate ten times the area now under …

Circular No. 1 - Memoranda Of Plans For Arid Farm Investigations Apr 1904

Circular No. 1 - Memoranda Of Plans For Arid Farm Investigations

UAES Circulars

The Legislature of 1903 made an appropriation for the purpose of conducting experiments on the possibility of growing useful crops without irrigation in various parts of the State of Utah. The work was placed under the direction of the Utah Experiment Station. Six farms have been located under this act, and cultural and other work has been begun. This circular which contains the plans of the proposed investigations has been prepared for the convenience of those employed in the investigations.


Bulletin No. 87 - The Codling Moth, E. D. Ball Mar 1904

Bulletin No. 87 - The Codling Moth, E. D. Ball

UAES Bulletins

The codling moth has been in the State of Utah for over twenty-five years and is now injuriously abundant in every apple-growing section. It is by far the worst pest with which the fruit grower has to contend. In fact, it usually does more damage than all the other fruit insects put together.

It occurs throughout every apple-growing region of the United States, and is found in almost every country where the apple is grown, destroying from one-fourth to three-fourths of the apple crop where no effort is made to check its ravages. Dr. Howard the United States Entomologist, recently …


Bulletin No. 86 - The Right Way To Irrigate, John A. Widtsoe Dec 1903

Bulletin No. 86 - The Right Way To Irrigate, John A. Widtsoe

UAES Bulletins

The irrigation investigations of the Utah Experiment Station w re instituted in 1901; and have been continued since that year. The results promise to be of the highest importance in the establishment. of correct practices in the use of water on the farms.


Bulletin No. 84 - The Grain Smuts, Lewis A. Merrill, B. F. Eliason Nov 1903

Bulletin No. 84 - The Grain Smuts, Lewis A. Merrill, B. F. Eliason

UAES Bulletins

Farmers are urged to treat all their seed grain with Formalin, during the coming spring, and thus save to the state, next year, thousands of dollars now lost by smut-infested grain.

Formalin can be purchased at any drug store for about seventy-five cents per pound. Pour one pound of Formalin in fifty gallons of water and completely submerge the seed grain, which is loosely held in burlap sacks, for ten minutes. Dry the seed and it is ready for use.


Bulletin No. 85 - Pear-Blight, W. N. Hutt Nov 1903

Bulletin No. 85 - Pear-Blight, W. N. Hutt

UAES Bulletins

This bulletin makes no claim to originality of method. It is simply a brief resume of the history and nature of pear-blight, together with the treatment of the disease that we have found to be most successful, during the last two years, at this Experiment Station. The bulletin is published in reply to numerous letters from many parts of the State asking for information regarding the blight of the pear trees, and methods of controlling it.


Bulletin No. 83 - Pruning Of Tree And Bush Fruits, W. N. Hutt Oct 1903

Bulletin No. 83 - Pruning Of Tree And Bush Fruits, W. N. Hutt

UAES Bulletins

"How shall we prune" is a question probably more frequently asked than any other in the whole range of horticulture. To answer it brings forth a second question, viz., "Why do we prune?" Pruning is a means to an end. So then to prune intelligently and therefore successfully, there should be in the mind of the operator some definite purpose. Too often pruning is simply a cutting of the tree without any idea as to the final purpose such cutting is to serve. Such pruning invariably does harm instead of good, and has ruined countless trees. Since the ultimate purpose …


Bulletin No. 88 - The Relation Of Smelter Smoke To Utah Agriculture, John A. Widtsoe Jul 1903

Bulletin No. 88 - The Relation Of Smelter Smoke To Utah Agriculture, John A. Widtsoe

UAES Bulletins

Utah's position among the great commonwealths depends upon the degree of development of the agricultural industry of the State. As a producer of wealth, however, the mining industry exceeds agriculture. The total annual value of Utah farm products is about $17,000,000.00, while the total output from the mines is valued at $34,000,000.00. The operation of the mines, reduction mills and smelters necessitates the employment of large numbers of people, who swell the population of the State, and consume a large part of its agricultural products. Utah, which is an inland State, possessing as yet few large manufacturing enterprises, finds the …


Bulletin No. 79 - Process Butter: A Dairy Fraud, R. W. Clark, John A. Crockett Jan 1903

Bulletin No. 79 - Process Butter: A Dairy Fraud, R. W. Clark, John A. Crockett

UAES Bulletins

A fraud which threatens to work great injury to the dairy interests of Utah, has made its appearance. It is a churning process by which the yield of butter can be abnormally increased by incorporating a large quantity of water and casein. A report has reached the Experiment Station to the effect that the promoters of this churning process are successfully enlisting the interest of Utah farmers and are selling county rights at fabulous prices.

This bulletin is issued only as a word of warning to those who would be entrapped. It is not probable that butter made according to …


Bulletin No. 80 - Irrigation Investigations In 1901, John A. Widtsoe Dec 1902

Bulletin No. 80 - Irrigation Investigations In 1901, John A. Widtsoe

UAES Bulletins

The fact that the ancient and, to arid countries, indispensible art of irrigation lacks a scientific basis, is the justification of the decision taken two years ago by the officers of the Utah Experiment Station, to make irrigation the central subject of their investigations.


Bulletin No. 78 - Experiments In Fattening Lambs, F. B. Linfield Sep 1902

Bulletin No. 78 - Experiments In Fattening Lambs, F. B. Linfield

UAES Bulletins

Sheep raising is among the most important agricultural industries of the state. Unlike the conditions in eastern states, the sheep industry of Utah is only indirectly associated with the farm. While the sheep owner generally lives on his farm, his sheep are kept on the public range and moved from place to place as feed and weather may make necessary. To be handled successfully on the range, sheep must be herded in large flocks. Under favorable conditions the expense account is comparatively light and returns substantial.


Bulletin No. 77 - Horse Feeding, Lewis A. Merrill Jun 1902

Bulletin No. 77 - Horse Feeding, Lewis A. Merrill

UAES Bulletins

Previous experiments reported by this Station have shown the value of lucern, the principal forage crop of this section, when fed to cattle, sheep and hogs. The main part of this bulletin is devoted to the value of lucern when fed to horses, though a brief review of the work previously done at this Station in connection with the subject of horse-feeding is included. There has been, and is, some prejudice existing against lucern forming a part or all of the ration of horses, not only in the East, where the value of this crop is not yet fully appreciated, …


Bulletin No. 76 - Forcing Lettuce, C. P. Close Mar 1902

Bulletin No. 76 - Forcing Lettuce, C. P. Close

UAES Bulletins

The winter growing of lettuce is not yet practiced in Utah. There is a good demand for lettuce in Salt Lake City, Ogden, and in some of the smaller towns during the winter, but this demand is supplied by the California grown product. It is yet to be determined whether or not lettuce can be grown profitably under glass in this State. The recent high prices of the winter product indicate that the forcing of a moderate amount of lettuce can be done with profit.

In the season of 1899-1900, the Experiment Station began a series of experiments with lettuce …


Bulletin No. 74 - Lead Ore In Sugar Beet Pulp, John A. Widtsoe, Lewis A. Merrill Jan 1902

Bulletin No. 74 - Lead Ore In Sugar Beet Pulp, John A. Widtsoe, Lewis A. Merrill

UAES Bulletins

The recent great development of the beet sugar industry in the State of Utah, has made the matter of utilizing the sugar beet pulp an important question for Utah farmers. That beet pulp has a high feeding value, when fed in proper combinations, has been shown conclusively since the establishment of the first beet sugar factory in the State, ten years ago. The experience of other states, and of the beet sugar producing countries of Europe, has likewise demonstrated that beet pulp may be used profitably in the feeding of farm animals. It is doubtlessly true that much is yet …


Bulletin No. 75 - Arid Farming Or Dry Farming, John A. Widtsoe, Lewis A. Merrill Jan 1902

Bulletin No. 75 - Arid Farming Or Dry Farming, John A. Widtsoe, Lewis A. Merrill

UAES Bulletins

There are in Utah many lands that will not, for many years to come, be brought under irrigation; and there are many others that probably will never be irrigated. These are usually high-lying lands, often far from large streams, to irrigate which, would require the construction of exceptionally costly reservoirs, dams, and canals. Many Utah valleys are so far removed from the water supply of the State that it is improbable that water will be carried past other thirsting lands to these outlying places. The building of irrigation works is a venture in which profits and losses are considered; and …


Bulletin No. 73 - Experiments In Butter-Making And Cheese-Making, F. B. Linfield Aug 1901

Bulletin No. 73 - Experiments In Butter-Making And Cheese-Making, F. B. Linfield

UAES Bulletins

No bulletins have heretofore been issued by the Dairy department of this Station on the special question of the manufacture of dairy products. The main work of the Dairy department has been with the farm end of the dairy problem; viz: the production of milk. This includes the breeding, feeding and management of cows, the raising and developing of the young stock, and the economic disposal of the by-products of the dairy. From information gathered during my first year at the College it was apparent that this foundation work should have first attention. At this time but six to eight …


Bulletin No. 72 - A Soil Survey In Salt Lake Valley, Utah, Frank D. Gardner, John Stewart Oct 1900

Bulletin No. 72 - A Soil Survey In Salt Lake Valley, Utah, Frank D. Gardner, John Stewart

UAES Bulletins

Beginning in July, 1899, four months were spent in a thorough and detailed study of that portion of the Salt Lake Valley lying west of the Jordan River, the object being to map the soils with reference to their character and to the extent of, and damage from, "alkali" and seepage waters. The soils were classified according to their texture, and the waters examined with reference to their quality for irrigation purposes. The soils were further studied with reference to their "alkali" content and its effect in varying amounts upon the crops and vegetation. The methods of irrigation were looked …


Bulletin No. 71 - Carrying Capacities Of Irrigation Canals, Samuel Fortier Jul 1900

Bulletin No. 71 - Carrying Capacities Of Irrigation Canals, Samuel Fortier

UAES Bulletins

During the summer of 1897 the writer was enabled to make, with the help of his assistants, T. H. Humpherys, A. P. Stover, and W. D. Beers, a number of experiments on the carrying capacities of irrigation ditches and canals. The funds necessary to carry on these investigations were provided by the U. S. Geological Survey and the Agricultural Experiment Station of Utah. Shortly after the field work was completed the writer resigned his position with the College to accept that of chief engineer and superintendent of the Ogden Water Works and the Bear River Canal System, and his time …


Bulletin No. 69 - The Golden Vine Field Pea: Its Chemical Composition And Forage Value, John Stewart Jun 1900

Bulletin No. 69 - The Golden Vine Field Pea: Its Chemical Composition And Forage Value, John Stewart

UAES Bulletins

For some time past the Division of Agrostology has been conducting investigations in various parts of the United States with a view to the preservation of our native grasses, the introduction of new varieties, and the improvement of the ranges. The investigation in Texas, where the once fine ranges have been seriously injured or totally destroyed on account of the greed and carelessness of stockmen, is an important one.

In his last report, the Secretary of Agriculture recommends that provisions be made for renting the public lands, suitable for grazing purposes, to stockmen and sheepmen for a number of years. …
