Agricultural Water Conservation Clearinghouse
Permanent URI for this community
The Agricultural Water Conservation Clearinghouse (AWCC) was superseded by the Irrigation Innovation Consortium in April 2018. The AWCC was a comprehensive information resource system with a central focus on agricultural water management and conservation. Subject areas covered Irrigation Systems, Ag Water Conservation Policy, Cropping Systems, Drought Tolerance, Water Supply and Storage, and more. These digital collections include topic specific conference proceedings, government documents, white papers, and reports.

Libraries, 1973) Morel-Seytoux, Hubert J., author; Young, R. A. (Robert Alton), 1931-, author; Radosevich, George, author; Colorado State University, Environmental Resources Center, publisherEven though the word Economics was left out of an already lengthy title, its importance was recognized in the study. The report, the outcome of a one-year study, is made of three parts dealing respectively with the hydrologic, legal and economic aspects of conjunctive surface-groundwater management. Hydrologist, lawyers and economists have become increasingly and even painfully aware of the complex degree of interaction of their respective disciplines and as a result they have attempted to establish a connection. This report emphasizes. the fact that the solution of the problem requires not just a mere juxtaposition of parts (a procedure acceptable as a start) but a complete integration from concepts down to coding details.Item Open Access Improvements in moving sprinkler irrigation systems for conservation of water(Colorado State University.

Libraries, 1976-07) Nabors, Murray W., author; Environmental Resources Center, Colorado State University, publisherMuch successful work has been done on altering the environment by irrigation to increase the amount of land in agricultural production, however the costs may increase as suitable water becomes more difficult to develop. The alternative may be to adjust the plants to accept lower quality water through selection for appropriate spontaneous mutants. Methods for the selection of desirable spontaneous mutants require the application of environmental pressure to give the mutant a competitive advantage and also require the examination of millions of individual plants. To accomplish this in field trials is time consuming and costly. Instead this project employs individual cells in tissue culture where ten million cells occupy 100 ml and each cell effectively is a plant, because a plant can be regenerated from an individual cell. Plant properties such as salt tolerance which is exhibited on the cellular level can be selected in tissue culture at much less cost due to the small scale required. The focus of this project has been toward the selection of salt mutants. Two lines of tobacco cells, tolerant to NaCl levels of 8000 ppm, have been selected while normal tolerance to NaCI in this species is 800 ppm. Plants have been regenerated from the tissue cultures at many levels of NaCI tolerance between these extremes, and these plants are currently being tested for NaCl tolerance and for mutation inheritability. Although practical tolerance needs may not exceed 2000-3000 ppm, the higher ranges of salt tolerance may yield mutants with better yields at the moderate tolerance levels. Considerable progress has been made toward tissue culture mutant selection systems for oats, wheat, soybean, corn, and sugar beets. Selection for salt tolerant mutants is currently underway for both oats and wheat.Item Open Access Water use and management in an arid region: Fort Collins, Colorado, and vicinity(Colorado State University.
