The Salt Lake Group In Cache Valley, Utah And Idaho, Robert D. Adamson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fluvial and lacustrine sediments of great thickness accumulated in the intermountain basins of the western United States during Tertiary time. The Salt Lake group in northern Utah and parts of surrounding states is a conspicuous stratigraphic unit of these basins. The "beds of light color" in Morgan Valley in the Wasatch Mountains of northern Utah were named the "Salt Lake group" by Hayden (1869) because of similar occurrences in Salt Lake Valley and because he reasoned that the succession could be divided into formations. Similar rocks crop out in Ogden Valley, north of Morgan Valley, and in Cache Valley, Utah …

The Influence Of Soil Moisture Conditions On The Absorption Of Phosphorus By Plants From Calcareous Soils, T. J. Denman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Phosphorus is one of the major plant nutrients secured from the soil. The object of many investigations has been to discover the nature of the processes by which the soil supplies phosphorus to plants, and to determine the influence of soil factors upon these processes. Although much knowledge has been gained, these processes and the effects of soil factors upon them are still not clearly defined.

One factor which profoundly affects plant growth is the amount and relative availability of soil moisture. The results of some investigations have suggested that this factor may also have considerable influence on the absorption …

A Management Study Of The Cache Elk Herd, Norman V. Hancock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

American elk, by virtue of their distribution, were the most cosmopolitan members of the cervid family at the time of white settlement of North America. At this early date elk were present in every major region of what is now continental United States, as well as in northern Mexico. they likewise were abundant in upper and lower Canada, though records do Lot corroborate their presence too far north on the Atlantic coast. Although generally existent throughout the western states, elk were sparsely distributed in Nevada, southern Utah, and most of Arizona and New Mexico. Paucity of elk was also noted …

Measurement Of Irrigation Water, Eldon M. Stock

Reports

Foreword: Although irrigation has been practiced in Utah for more than one hundred years, irrigation water still is being distributed to farmers with little or not thought about its measurement. A farmer would not think of buying or selling other farm commodities, such as hay, grain, beef cattle, or dairy products, without weighing or accurately measuring them, but at the same time he is often content to accept and pay for the irrigation water received with little or no knowledge as to the actual amount received, or whether or not he is receiving the amount he is entitled to. Measurement …

Growth And Nutrition Of Plants As Affected By Various Levels Of Exchangeable Sodium, Mohammad B. Choudhri

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In saline soils, which are characterized by an appreciable quantity of neutral soluble salts, plant growth is adversely affected due to the increase in osmotic pressure and the consequent decrease in the physiological availability of water. In addition, growth may also be restricted through the accumulation of toxic quantities of various ions within the plant.

On the other hand, alkali soils, whether saline or non-saline, are characterized by a high content of exchangeable sodium in the cation-exchange complex. One reason of low productivity on these soils is the unfavorable physical conditions induced by the dispersing action of the sodium ions. …

The Content Of Essential Amino Acids In 1950 Alfalfa Hay Grown In Utah Soil Treated With Different Fertilizers, Adriana Lanting Kunkel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Application of fertilizers to soils to increase production yields has raised questions concerning the effect of fertilizer on chemical composition of plants. With the development of accurate, sensitive microbiological methods for the determination of amino acid in protein, speculations concerning amino acid content have been supplanted by acquisition of facts.

The effect of the different fertilizer applications on alfalfa yield has been discussed by Jones, et al (5). Also, some work has been done to determine the effect different fertilizers might have on the amino acid content of plant material. Some values (1,3,12) have been reported for the amino acid …

Soil Additives And Their Effect On The Yield Of Various Crops And The Physical Properties Of An Agricultural Soil, Gaylen L. Ashcroft

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is generally accepted that soil structure is very important in keeping productivity at a high level. When soils are loose and friable, mechanical impedance to root growth and seedling emergence is greatly reduced. Such soils infiltrate greater quantities of precipitation, are better aerated, and possess a more favorable temperature than puddled soils. Essential plant nutrients are also more easily available in well aggregated soil.

In the last few years, several synthetic soil additives have been placed on the market. Extravagant claims have been made about the ability of these amendments to maintain soil structure, without a sound body of …

Evaluation Of Sprinkler Irrigation Systems In Northern Utah, Jay M. Bagley, Wayne D. Criddle

Reports

Summary and Conclusions: Sprinkler irrigation will continue to expand in Utah as well as in other irrigated areas of the world. This method of irrigation is suitable to all farm crops grown in the state and to most soils. It is particularly adapted to steep foothill areas where the water supply can be obtained at higher elevation and pumping is not necessary to develop pressure for the sprinkler systems. Also, much of the irrigated land of the state, particularly along the Wasatch front, is owned and operated by "part-time" farmers. Having the water under complete control and the irrigation schedule …

Effect Of Bicarbonate Ion And Root Aeration On Lime-Induced Chlorosis, Willard L. Lindsay

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Chlorosis in plants has been recognized as a devastating disease for over one-hundred and fifty years. It is easily recognized by a yellowing of the plant foilage and is associated with a reduced chlorophyll synthesis.

Chlorosis is found so frequently on calcareous soils that its cause is attributed at least in part to this soil factor. It is therefore referred to as lime-induced chlorosis. This type of chlorosis has become a serious problem, especially in many of the fruit-growing regions of Europe and the Western United States where the soils are calcareous. In Utah the disease is more destructive than …

The Reaction Of Some Sodium Salts Of Fatty Acids And Benzoic Acid With Α-Bromobenzyl Cyanide, Richard W. Perkins

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fife (4) and O'Shaughnessy (12) have made a series of di-esters by allowing the sodium salts of various fatty acids to react with ethyl monochloracetate according to the following equation:

RCO₂Na ≠ ClCH₂CO₂C₂H₅ ---------> RCO₂CH₂CO₂C₂H₅ ≠ NaCl .

The mechanism of the reaction appears to be ionic and to involve the attack of an RCO₂^- ion on the carbon atom to which the chlorine atom is attached. As the RCO₂^- approaches this carbon atom the chlorine atom moves …

Some Effects Of Fluctuating And Falling Water Levels On Waterfowl Production, Kenneth E. Wolf

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are today many areas and types of water storage. The uses to which these are put are many, and the prospect for the future can only be that there will be an increase in the number of these reservoirs. These areas are usually operated with regard only for power production, irrigation, or storage, but there is a growing concern about the effects on wildlife which this type of operation may have. Fluctuating water levels, and falling water levels are not restricted to man-made impoundments tut are characteristic of many of then. Biologists have observed that these variations in water …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Vitamins play an important role in the nutrition of man and animal. As early as 1897 Eijkman was able to demonstrate the symptoms of thiamine deficiency disease in birds. Since then, vitamins have been regarded as one of the most essential factors in nutrition. Only small quantities in the diet are necessary, yet lack of any of them will inhibit the growth and produce certain kinds of deficiency diseases.

The Freezing Point Of Water In Puddled And Unpuddled Soils At Different Soil Moisture Tension Values, Robert B. Campbell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A technique that will adequately describe the physical condition of water in the soil has long been desired by scientists. The method should include the effect of soluble materials on the osmotic pressure of the soil solution, and also the effect of surface force action between the soil and soil water.

Parker (8) demonstrated that the freezing point was reduced in the presence of finely divided material. This suggested the possibility of using the cryoscopic procedure to measure the physical condition of water soil. More recently, the introduction of Thermistors for accurate temperature measurement have made it desirable to investigate …

Relative Productive Value Of Land, Karl Harris, Vaughn E. Hansen

Reports

Location, markets, hard surface roads and other transportation facilities, churches, taxes, schools, and utilities are major factors in the monetary value of land, yet these things do not contribute to the land’s productivity. In this bulletin the only factor considered in determining the agricultural value of land is its productive capacity.

The three major factors in the productive value of land are water, climate, and soil.

These three factors are the principal ones in crop production. If any one of them is unfavorable to plant growth, it can inhibit or even prevent plant growth regardless of how favorable the other …
