The Influence Of Soil Compaction Upon The Thermodynamics Of Soil Moisture, James E. Box Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The retention of water in soils is a very interesting subject. Soil-water research presents a great challenge to research workers. The challenge is broad in scope and extends from the field problems of large irrigation projects to the atomic scale of the solid-liquid interface.

If scientists are going to describe scientifically soil-water relations, they must ultimately utilize the instruments of science and the language of mathematics. To the end of the latter the mathematics of thermodynamics has been applied in these studies of water retention in soils.

Phosphorus Status Of Genola Soils In Utah, Warren E. Bendixen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With increasing pressure on economical production of crops, more fertilizers are being applied to the soil each year to increase crop yields. Economical production of crops with applications of fertilizer requires an evaluation of the essential elements of the various crops so applications of fertilizer will not exceed the law of diminishing returns.

Because varying soil, moisture, and climatic conditions influence the response to added fertilizers, some workers (18, 26, 38) have contended that the only reliable way of determining the fertilization needs of a crop is to conduct a trial on the particular farm. The length of time involved …

The Mineral Content Of Various Sections Of Some Plants As Influenced By Conditions Associated With Lime-Induced Chlorosis, Hyrum Del Var Petersen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The so-called "lime-induced" chlorosis has been recognized for many years as a problem where plants are grown on calcareous soils. The characteristics associated with lime-induced chlorosis are the same as those associated with iron deficiency chlorosis--interveinal yellowing of the leaves at the meristemic region combined with reduced vigor of the plant as a whole. Lime-induced chlorosis is unique in that the iron content of both chlorotic plant and the soil do not always show a deficiency in iron when chemically analyzed. This leads to the theory that iron is inactivated in both the soil and plant.

Although no single factor …

Sedimentation And Diffusion Coefficients Of Legoglobin Fractions, Alfonso R. Trujillo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The preparation of root nodule extract by Virtanen, et. al., has created a good deal of interest in the study of plant hemoglobin (legoglobin). In the preparation of any new substances, it is of interest to determine the physical constants of the new species.

Predicting Mathematics 34 And 35 Grades At Utah State University, Donald N. Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Incoming freshman students are confronted early in their college career with the problem of selecting a program of study that fits their needs, capacities and interests. Counselors and advisors have found that a large number of students do not give prior deliberation to the selection of a major field of study. For the most part, students use a trial and error method in making their choices. That is, their choice is a result of success in previous class work. Although some effort is being made by educational personnel to resolve this problem, a large amount of objective research remains to …

Life History Notes On The Walleye, Stizostedion Vitreum Vitreum (Mitchill) In A Turbid Water, Utah Lake, Utah, Billy B. Arnold

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Early in 1952, walleye fry were stocked for the first time in Utah Lake. Subsequent plants were made in 1954, 1955 and 1956. Altogether, over two million fry have been stocked.

By January, 1958, it was felt sufficient time had elapsed for the species to establish patterns of growth, reproduction, food habits and consequent relationships to the new environment. Thus, on January 1, 1958, a Federal Aid to Fisheries project, number DJ F-4-R-5, job T, was initiated. This project was entitled "investigations of Yellow Pikeperch and Channel Catfish of Utah Lake, Utah County." Although the closing date was December 31, …

The Effect Of The Method Of Irrigation And Fertilizer Application On The Movement Of Nitrates In The Soil, Lavoir A. Banks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is generally recognized that one of the most important factors limiting crop production is soil nitrogen. Farmers today are using more nitrogen fertilizers than ever before. All indications show that this usage will probably continue to increase. With the expanded use of nitrogen, it has become desirable to increase the efficiency from nitrogen fertilizers. One factor which will affect the efficiency is the position of the nitrogen in the soil in relation to the plant roots.

Hydrogen Bonding Between The Carbonyl Group And Wyoming Bentonite, Robert A. Kohl

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The vibrational frequencies of atom to atom bonds within a molecule are a function of the bond energies. Each bond has its characteristic frequency, and most of these frequencies can be detected with the infrared spectrophotometer. When one compound reacts with another or is adsorbed on the surface of a solid, detectable frequency changes or shifts may occur. These changes or shifts yield valuable information about the bonds which are formed or broken.

Studies In Iron Chlorosis Of Leaves, Narayan Gunderao Perur

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Normal healthy growth and development of plants is controlled by certain factors known as factors of plant growth. They are soil, climate, and plant inheritance. The soil contains many nutrient elements needed by plants both in macro and micro quantities. Iron is one of the essential elements required by plants in small amounts.

When plants are starving for any of the essential nutrients, characteristic symptoms usually appear as certain abnormalities, discoloration and deformation of leaves, fruits, and other parts. The deficiency symptoms, though not easily recognizable in some cases at the beginning, are quite apparent in advanced stages of plant …

The Temperature Dependence Of The Drying Of Horizontal Soil Columns, Craig Loren Wiegand

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A consideration of the physical principles involved in evaporative drying of soil indicates that several physical processes might possibly limit the rate of evaporation. These include the rate of supply of energy to the site of evaporation, the rate of transfer of water vapor through the sample or through the atmosphere above the sample, and the rate of unsaturated flow of water to the soil surface or to the site of evaporation.

A Political Study Of Federal Aid To Education At Utah State University, Richard Yates Merrell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the present-day world of change, every time we pick up the paper we read of something new in our society. We now have new rockets, new satellites, new computers, and new methods or destruction. There are also many "new" things in the field of education. One of these is federal aid to education. As yet, there seems to be no consensus on the merits of this supposedly new approach to educational finance. Some view it as a kind or plague; others see it as an unmixed blessing. Actually, federal aid to education is quite old and quite common.

The Influence Of Soil Moisture Suction And Evaporative Demand On Actual Evapotranspiration And Yield Of Alfalfa, Bozorg Bahrani

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Evapotranspiration has been defined as the combination of evaporation of water from the soil surface and transpiration of water by vegetation. If the ground is well covered by plants, most of the water is lost by transpiration of water directly from the plant tissue, rather than by evaporation of water directly from the soil surface. The term consumptive use is synonymous with evapotranspiration.

Interaction Of Riboflavin With Molybdenum, Jacques Tocatlian

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Molybdenum may function as a catalyst in promoting and controlling some of the complex chemical reactions that go on in living systems. The lack of understanding which exists about these reactions is due to their obvious complexity and to the extremely minute quantities of molybdenum involved. Traces of molybdenum have been shown to have spectacular results on the growth of plants when added to certain soils. This metal is also required for the growth of azobacter, the nitrogen-fixing bacteria (1).

Molybdenum has been shown to be present in four enzymes: nitrate reductase (2), hydrogenase (3), xanthine oxidase (4) and aldehyde …

The Effects Of Flouride Ion On Some Blood Constituents Of Rainbow Trout, Salmo Gairdneri, Linnaeus, Richard H. Alger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the past quarter of a century there has been considerable investigation into the effects of fluorides on living organisms. It has been well established, as a result of these studies, that both small and elevated amounts of fluorides present in the environment may have a marked toxic effect upon gaining entry into the organism. Much of the research involving fluorides and the living organism has been confined to experimentation with animals, although considerable evidence indicates that plants are also subject to injury if fluorides are present in the atmosphere or the soil.

The great majority of the research dealing …

Lethal Concentrations And Detoxification Time Of Toxaphene For Goldfish, Gambusia And Rainbow Trout, Gar W. Workman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the past few years the Utah Fish and Game Department, as well as the fish and game departments of other states, has been spending fisheries money for fish eradication on both lakes and streams. The Utah Fish and Game Department recently suggested to the University that research be initiated on the subject of toxaphene as a fish poison. Consequently, a better insight into conditions that exist for a given water type could be developed.

The Effect Of Nutrient Levels In Nutrient Cultures On The Translocation Of Foliar Applied Nutrients, David D. Neher

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since man first grew crops on calcareous soils he has probably been troubled with what we today call lime-induced chlorosis. This chlorosis has determined whether he grew certain desirable ornamentals or crops or whether he had to substitute others which were less desirable.

Lime-induced chlorosis is spread world wide. It has been reported in the vine and fruit growing regions of Europe, in the chernozem soils of Russia, and many other areas where the rainfall is relatively low and the soil is relatively high in calcium carbonate. In the United States it most frequently occurrs where the average annual rainfall …

A Survey Of The Use Of Standardized Tests In The Junior High Schools Of Weber County, Ashlaug J. Jackson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is evident from the literature reviewed that there is a need for better understanding and utilization of standardized test results. It seems that unless tests contribute to the learning process they are not justifiable. Merritt (12, p. 66) says the main objective of all endeavor is to promote learning. Ultimately, the worth of any activity carried on in the schools has to be judged by the contribution this activity makes toward the improvement of learning. Testing is no exception. In a broad sense, desirable learning has taken place when behavior has been changed in socially approved directions. Testing is …

Studies On The Sampling Methodology Of Peas For Yield And Quality, Pratapsinha Chintamani Pendse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pea¹ growers have much at stake in getting high yields of peas of prime quality. The income accruing from a pea crop grown for processors is determined by the yield as well as quality. Therefore the farmers' efforts are directed toward growing such a crop.

Research workers are interested in knowing the yield of peas with known tenderometer values which will indicate the quality of peas. Present methods of field harvesting are costly and time consuming which tend to limit the number of varieties that can be satisfactorily evaluated for trial.

A comparison of sampling techniques with present harvesting …

Streamflow Forecasting For Blacksmith Fork River, Utah, Yu-Si Fok

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The method for streamflow forecasting by using Fourier Series and Multiple Regression as a mathematical model have been suggested and proved with high accuracy for the streamflow forecasting on Logan River, Utah by Professor Cleve H. Milligan and Dr. Rex L. Hurst. ^1/

In this thesis the method is extended to the forecasting for the Blacksmith Fork River, south of the Logan River.

Because the climatological data are not available in the Blacksmith Fork watershed, this thesis also provides a technique for using the available data from adjacent watersheds.

A Comparison Of Internal Bicarbonate Of Some Chlorosis-Resistant And Chlorosis-Susceptible Plants, Ralph Barlow Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Iron chlorosis has been a srious problem for many years. This physiological disease has occurred so frequently on calcareous soils that it has been called lime-induced chlorosis by many of the workers. Because the western United States has so many soils of this type, the chlorosis problem has been of primary concern. Untold economic losses have been the result of this physiological disease.

Interveinal yellowing of the leaves along with loss of plant vigor and retarded growth characterize the disease. In severe cases die-back of the terminal growth and eventual death of the plant result. No single factor has been …

Development And Evaluation Of Laboratory Methods For Determining The Nitrogen Supplying Power Of The Irrigated Soils Of Northern Utah, Jerald Ross Wight

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nitrogen is the most widely needed and the most widely used of the fertilizer elements. Yet, in spite of the voluminous research work of evaluating the nitrogen status of soils, laboratory tests for the purpose of predicting need of nitrogen fertilizer are not very widely used. In general, laboratory tests for nitrogen supplying power have not given satisfactory results. Methods currently employed by a few laboratories can be classified either as biological or chemical. In the former method, the soil is incubated under optimum conditions and the amount of nitrate released over a given period of time is measured and …

The Influence Of Age On The Cation Exchange Capacity Of Plant Roots, Einard S. Haniuk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A yellowing which develops in some plants growing on naturally calcareous soils is called lime-induced chlorosis. The problem is complex, as indicated by Brown and Holmes (1956) and Porter and Thorne (1955). Species and varieties of plants differ in their iron requirements, susceptibility to lime- induced chlorosis, and inter acting soil f actors which affect iron supply (Thorne et al 1950). Chlorosis of plants does not appear, therefore, to stem from a common causative factor. At least a part of this difference has been found to be associated with the plant roots. Thus, through the use of resistant root stock …

A Manometric Method For The Determination Of Soil Carbonates In The Field, N. A. Polyzopoulos

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In soil survey work the method now generally used to evaluate the carbonate content of the soil in the field is to observe the amount of effervescence that takes place when the soil reacts with dilute acid. The four degrees of effervescence usually recognized are designated by the symbols eo, e, es, ev and correspond roughly to a lime content of 0-0.5, 0.5-3, 3-15, and above 15 per cent, respectively. This, or course, is a very rough estimate and therefore a method is needed for the quantitative determination of carbonates in the field with a fair degree of accuracy. If …

Ferrilegoglobin As An Oxidizing Agent For Hydrazine, Donald B. Larson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The system in which atmospheric nitrogen succumbs to enter Nature's cycle has a yet proven evasive with respect to the actual chemical reactions. At present several types of systems are proposed but their chemical makeup is practically unknown.

A Study Of The Sequence Of The Professional Education Program For Elementary School Teachers At Utah State University, Christopher Lee Colston

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Education, like any other profession, is responsible for constant improvement. The professional teacher education institutions are constantly looking for ways of improving professional teacher education programs. The course sequence of the teacher education program is an area for continual improvement. Every teacher educator has a theory as to what is the best teacher education program and what is the best sequence for this theory program. The literature has revealed very little in the area of a sequence for the teacher education program.

Geology Of The Northern Part Of Wellsville Mountain, Northern Wasatch Range, Utah, Stanley S. Beus

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wellsville Mountain forms the extreme northern end of the Wasatch Range in northern Utah. It lies at the western margin of the Middle Rocky Mountain province and is bordered by valleys of the Basin and Range province. Many geologic investigations have been made in this region. Much of the Wasatch Range has been studied and mapped as well as parts of the Bear River Range, east of Cache Valley, and the Malad Range which extends north from Wellsville Mountain; however, the geology of Wellsville Mountain has not been studied or mapped in detail. Some reconnaissance mapping has been done and …

A Study Of The Holding Power Of Utah State University With Respect To A Selected Group Of Superior Entering Freshmen, Dan J. Workman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Current literature may not agree, but it seems safe to say that to the educator, the academically superior student has always held a great deal of interest. All institutions of learning desire to attract and retain students with high scholastic potential. This is evidenced by the present concern as to whether or not superior students are being adequately provided for in the schools.

Geology Of The Southern Part Of Wellsville Mountain, Wasatch Range, Utah, Ronald H. Gelnett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wellsville Mountain is 10 miles west of Logan, Utah, at the northern extremity of the Wasatch Range. Paleozoic rocks form a northeast-dipping homocline bounded in part by northwest-trending high-angle faults and cut by a series of northeast-trending high-angle faults. A major transverse fault, with a stratigraphic displacement of 4,500 feet, divides the mountain into two distinct blocks.

The rock units of the area are comparable to those of the Logan quadrangle immediately to the east. Pre-Cambrian rocks crop out in Box Elder Canyon, just east of Brigham City, and are overlain by at least 20,000 feet of northeast-dipping Paleozoic rocks …

Horizontal Movement Of Moisture In Soil, D. W. L. Read

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The movement of water in soils is of great importance to all of us but especially to agriculturalists. If it were not for this movement plants would not be able to survive in soil. If the moisture moves too freely in the soil insufficient water can be stored to supply plants during dry periods. The movement of water through soil may remove plant nutrients or accumulate salts in soil horizons.

The flow of water in soil has been studied extensively for many years. Water movement can occur in either saturated or unsaturated soil. Darcy's law can be used with a …
