Irrigation System Distribution Uniformity Evaluations in the Pajaro Valley, California- Juniper publishers
Journal of Agriculture Research - Juniper Publishers The Resource Conservation District (RCD) of Santa Cruz County and the UC Cooperative Extension of Monterey County performed 25 distribution uniformity (DU) evaluations in the Pajaro Valley between September 2015 and July 2017 following a method developed by Dr. Mike Cahn from the UC Cooperative Extension of Monterey County. The evaluations were performed in collaboration with interested growers and resulted in reports with recommendations to improve the performance of the irrigation system. An estimate of the potential savings, in terms of water and costs, were also included in each evaluation. Funding for the project came from PVWMA and from DWR. Distribution uniformity is a measure of how evenly water is delivered to the crop and is an indicator of the efficiency of the irrigation system. Less water needs to be applied for a system with a high DU to meet the crop demand than a system with low DU. By impro...
