An Investigation Of Methods For Estimating Marginal Values Of Irrigation Water, Richard L. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Marginal values of water used in irrigation are needed if water is to be optimally allocated among alternative uses. Cobb-Douglas production function analysis and linear programming methods were studied in this investigation to find their fruit-fulness in predicting these marginal values. The theoretical properties of both methods indicate that they are conceptually capable of yielding valid marginal value estimates for irrigation water.

Further investigation of the two methods was carried out as an empirical test in the Milford area of Utah. Marginal values of water used for irrigation in that area were estimated by both procedures. Although inviolable criteria for …

Experiments On The Inactivation Of Zinc By The Mineral Fractions Of The Soil, John J. Hassett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Zinc deficiency, in many cases, is closely related to organic matter decomposition. DeRemer and Smith (1964) studied the effects of decomposing sugar beet tops on the reactions of Zn⁶⁵ in a Portneuf soil. They found that with time the Zn⁶⁵ associated with lime minerals, exchangeable, and water soluble fractions of the soil decreased, while that found with the organic and mineral fractions increased. This increase in the mineral fraction is of particular interest, since the majority of the Zn⁶⁵ was found to be with this fraction after a period of time. They also showed that the increase …

Design Optimization Using Model Estimation Programming, Richard Kay Brimhall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Model estimation programming provides a method for obtaining extreme solutions subject to constraints. Functions which are continuous with continuous first and second derivatives in the neighborhood of the solution are approximated using quadratic polynomials (termed estimating functions) derived from computed or experimental data points. Using the estimating functions, an approximation problem is solved by a numerical adaptation of the method of Lagrange. The method is not limited by the concavity of the objective function.

Beginning with an initial array of data observations, an initial approximate solution is obtained. Using this approximate solution as a new datum point, the coefficients for …
