How Well Does Your Irrigation Canal Hold Water?, Robert Hill

All Current Publications

Irrigation canals placed in native soil or lined with earth can have seepage water losses varying from 20 percent to more than 50 percent. Well designed, new compacted earth lined canals can have reduced seepage losses similar to concrete lined channels. However, consistent and regular maintenance is required to keep seepage losses low. Older concrete lined canals with deteriorated joints and frost heave or settled sections may also have high seepage losses and require rehabilitating.

Energy Conservation With Irrigation Water Management, Robert Hill

All Current Publications

Irrigators in Utah experienced rapidly increasing energy costs from the mid 1970s to the late 1980s. These costs remain relatively high. Those who are pumping from deep wells are particularly interested in ways to cut back on energy use without doing away with profitability or production

Best Management Practices To Minimize Nitrate Leaching For Irrigated Potatoes, Robert W. Hill, Ahmad Y. Ranjha

All Archived Publications

Nitrate nitrogen (N03-N) leaching is becoming an alarming threat to ground water in many areas in the U.S. In one study in North Carolina, over 9000 domestic wells were sampled for nitrate. Over 3 percent (288 wells) contained N03-N at levels exceeding the Environmental Protection Agency (EPA) safe drinking water standard of 10 mgIL (Jennings, et aI., 1991). Ground water quality concerns in central Nebraska surfaced in the mid 1950s when scientists observed increasing N03-N concentrations in the ground water of some river valleys (Olson et aI., 1962). In Utah also, excessive N03-N contamination has been found in private wells. …

Pesticide Movement In Response To Furrow Irrigation And Pesticide Parameters, Richard C. Peralta, Robert W. Hill, Howard Deer

All Archived Publications

Production of adequate supplies of food and fiber currently requires that pesticides be used to limit crop losses from insects, pathogens, weeds and other pests. The term pesticide refers to a large number ofchemical compounds. Pesticides include acaricides, fungicides, herbicides, insecticides, nematicides, algicides, arboricides, zoocides, and many more.

Alfalfa Production As Related To Irrigation Scheduling: An Economic Perspective, Craig L. Israelsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study analyzed the economics of irrigation scheduling for alfalfa hay in the Cache Valley, Utah area. Yield, evapotranspiration (ET) and irrigation drainage loss, along with the costs and returns per acre attributable to irrigation scheduling, were simulated through the use of a computerized plant growth model. The model created yearly "irrigation schedules" for alfalfa hay based on actual climatic, soil and plant characteristic data from the Utah State University Greenville Experiment Station. The model calculated the irrigation schedules based on a soil-water balance equation which never allowed the available soil water to go below the crop stress point.

Irrigating For Rainbows, Jack Keller

Faculty Honor Lectures

Quite simply. irrigation is the act of applying water to land. It is usually done to improve plant growth and it lies somewhere between an art. a science. and plain hard work. Even though we do not often think about it. irrigation is very important to the well-being of the world. It is important because we need basic foods to survive. and luxury foods and pleasant views to enjoy this survival. For the many people directly involved in irrigation. especially farmers. it provides a livelihood which is both satisfying and peaceful. And for the few of us lucky enough to …

Irrigation And Non-Irrigation Alternatives For Reducing Sugar Cane Transportation Costs In Santa Cruz, Bolivia, Lee M. Bailey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The major objective of this study was to investigate various alternatives for lowering the cost of transporting sugar cane in Santa Cruz, Bolivia. These alternatives included both irrigation and non-irrigation possibilities. Production costs for sugar cane were determined by using studies completed by the USAID-Utah State University study team, budget studies of Senor Carlos Castro of the Guabira' sugar cane mill in Santa Cruz and a study undertaken by Senor Enrique Gomez, a graduate student at Utah State University.

A cane registry commissioned by the National Sugar Cane Commission was used in conjunction with a least-cost transportation model in order …

Estimating Agricultural Production Functions From Experimental Data For Different Crops In Relation To Irrigation, Fertilization And Soil Management In Northern Utah, Subramaniuam Swami Nathan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Estimates of agricultural production functions from experimental data for four different crops in relation to six variable inputs are calculated by this study. There are four basic sections in the study. The first section covers the review of production function concepts and the procedures and problems that specifically pertain to this study. Also the importance of joint economic-agronomic research efforts, methodologies and applications of agricultural production functions are cited.

The second section includes the presentation data and postulated functional relationships in estimating production functions. Model building programs are used in developing three dimensional figures, which aid in the selection of …

The Secondary Benefits Of Irrigation Water: An Economic Appraisal, Erik Bruce Godfrey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The secondary or external benefits of increasing the availability of water for irrigation and changing the allocation of an existing water supply was analyzed from a theoretical point of view.

"Input-output" models for Cache County, Utah, and for the state of Utah were used to indicate the intersectoral relationship of water used by agriculture and other sectors in each economy.

The indirect value of water used by agriculture in Cache County was estimated. A method that extended the procedure used in this thesis was proposed that could be used to estimate the value of water in ether sectors. A "water …

Irrigation Water Values In Cache County, Utah, Marlyn Fife

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In Utah all water, both on or below the ground surface, is considered public property. The right to use water is obtained by following certain subsiding procedures of appropriation through the office of the State Engineer. Any right to the use of water may be changed to some other beneficial use with the approval of the State Engineer; however, there must be no interference with other rights, unless proper compensation has been made.

Agriculture still uses most of the available water in Utah; However, farmers' needs for water are not exactly the same. When allocation per acre is the same …

Utah's Future Water Problems, Wayne D. Criddle

Faculty Honor Lectures

Utah is rapidly changing from what was once predominately an agricultural state to an urban and industrial state. This shift is not decreasing our water needs; it is often intensifying these needs and creating many new problems. Perhaps we should ask ourselves-are we prepared to recognize and accept these changes? Are we really facing up to the problems that are developing or are we turning our heads and hoping they will go away? These changes involve technical, legal, and sociological problems never before encountered, some of which I should like to discuss.

Before attempting to look at Utah's water problems …
