2014 Irrigated Pasture Workshop-4-3-14 Los Molinos CA
2013 Orchard Irrigation Presentations
BASIC RRIGATION MANAGEMENT TOOLS - 23 SLIDES This presentation introduces three different types of tools and approaches to help decide when to irrigate orchard crops and how much water is needed.
IRRIGATION SCHEDULING IN ALMONDS AND WALNUTS - 22 SLIDES This presentation expands on the basic presentation above. It focuses on specific examples in almonds and walnuts. ET (Evapotranspiration) water budget, soil moisture monitoring, and pressure chamber measurements of midday stem water potential are applied to demonstrate how each irrigation scheduling method may help make irrigation management decisions.
IRRIGATION MANAGEMENT TOOLS FOR DEVELOPING ORCHARDS - 34 SLIDES This presentation focuses specifically on the pressure chamber to measure midday stem water potential and soil moisture monitoring to guide irrigation management decisions in young, developing orchards. ET estimates for young developing trees ranging from 1st through 4th leaf development are also provided. These ET estimates are site specific and influenced by management of orchard floor vegetation and the method of irrigation.
REVIEW OF RESEARCH: WATER MANAGEMENT IN DECIDUOUS ORCHARD CROPS - 82 SLIDES This presentation provides a more comprehensive review of irrigation research that has been conducted in almonds, prunes and walnuts over the past two or three decades. It also provides suggestions for further reading.
