Agenda: Boundaries And Water: Allocation And Use Of A Shared Resource, University Of Colorado Boulder. Natural Resources Law Center

Boundaries and Water: Allocation and Use of a Shared Resource (Summer Conference, June 5-7)

Conference organizers and/or faculty included University of Colorado School of Law professors David H. Getches, Lawrence J. MacDonnell and Charles F. Wilkinson.

Boundaries and Water: Allocation and Use of a Shared Resource is the topic of the Center's annual summer program on water this June. Most of the major rivers in the western United States are shared between two or more states. Often tribal governments play an important role in water allocation and use decisions. International considerations also may be involved in some cases. These interjurisdictional issues extend to groundwater as well as surface water.

This conference will provide the …


Improving Irrigation Scheduling And Water Use Efficiency In Cotton, Derrick M. Oosterhuis Jun 1989

Improving Irrigation Scheduling And Water Use Efficiency In Cotton, Derrick M. Oosterhuis

Technical Reports

Cotton (Gossypium hirsutum L) is an important crop in the southern United States. The crop is grown in both irrigated and rainfed situations and is seldom free from periods of water shortages at some stage during the season. In recent years the need for consistency in yields and a stable cash flow has resulted in a rapid expansion in the number of irrigated acres of cotton in the Mississippi Delta. Irrigation research has, however, not kept pace with this expansion. This project represents a start at meeting this urgent need. The influence of weather patterns necessitates that these studies be …

Reversible Tile Subsurface Drainage And Irrigation, Monroe Rasnake, Lloyd W. Murdock Feb 1987

Reversible Tile Subsurface Drainage And Irrigation, Monroe Rasnake, Lloyd W. Murdock

Soil Science News and Views

There are more than 900.000 acres of cl ass IIw land and 800,000 acres of class IIIw land in Kentucky. All of this land is suitable for row crop farming if it can be drained. Most of the problems are with internal drainage, some of which can be improved by installing drainage title.

Effect Of Soil Water Stress And Irrigation On Growth, Yield And Quality Of Burley Tobacco, Ronald E. Phillips, J. E. Leggett Jul 1986

Effect Of Soil Water Stress And Irrigation On Growth, Yield And Quality Of Burley Tobacco, Ronald E. Phillips, J. E. Leggett

Soil Science News and Views

An experiment was conducted for a period of three years, 1982, 1983 and 1984, in order to evaluate the effects of soil water stress and irrigation on growth, yield and quality of burley tobacco at Spindletop Farm, Lexington. The variety KY 21 was grown all three years. Three treatments were used in the experiment: (1) check, rainfall only, not irrigated, (2) well watered, rainfall plus supplemental irrigation, and (3) water stressed beginning 50 days after transplanting. The soil of treatment 3 was covered with black plastic to prevent rainfall from entering the soil.

Boron Composition Of Alfalfa In Utah As Related To Soils And Irrigation Waters, Robert N. Radtke Jr. May 1986

Boron Composition Of Alfalfa In Utah As Related To Soils And Irrigation Waters, Robert N. Radtke Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Eighteen field plots at 15 locations were selected throughout the state to evaluate the status of the boron content in irrigation waters, soils, and alfalfa (Medicago sativa) plant tissue under irrigated conditions.

No boron deficiency symptoms were observed in any of the alfalfa plants at any of these locations, nor were any of the plant tissue boron levels inadequate. Only two locations were found in which the alfalfa plants exibited toxicity symptoms. These locations were along the Indian and Antelope Creeks in Duchesne County which contain high boron levels in the water. All the alfalfa and soil tested …


Draining Irrigation Areas, K S. Cole, J P. Middlemas Jan 1985

Draining Irrigation Areas, K S. Cole, J P. Middlemas

Journal of the Department of Agriculture, Western Australia, Series 4

Many irrigation schemes throughout the world have turned into unproductive saline flats and swamps. This dramatic change can occur within a few years of irrigation starting and has been part of irrigation schemes from earliest times up to the present day.

The main cause of this salinisation is normally excess irrigation water use combined with poor drainage. Any form of waterlogging will have an adverse effect on plant growth.

Effect Of Irrigation On Corn, Soybeans And Alfalfa Yields In Kentucky, Lloyd W. Murdock Dec 1983

Effect Of Irrigation On Corn, Soybeans And Alfalfa Yields In Kentucky, Lloyd W. Murdock

Soil Science News and Views

Irrigation is not widely used in Kentucky for two reasons: 1) high average yearly rainfall, and 2) lack of easily accessible and dependable water sources. However, even with the high yearly rainfall, droughts do occur during the growing season. According to past history, they are more likely to occur in West Kentucky than Central Kentucky and least likely to occur in East Kentucky.
