Designer/Manager School of Irrigation
The Designer/Manager School is a comprehensive educational program offering a variety of classes designed for both agricultural and landscape irrigation professionals, taught by the very people who developed them - Charles M. Burt (Ph.D., P.E., CID); Stuart Styles (D.Engr., P.E., CID); and Franklin Gaudi (Ed.D., CID, CAIS). The classes are held at the ITRC facilities at Cal Poly State University, San Luis Obispo.
Our objective is to offer you an excellent opportunity to:
- receive practical information on key irrigation design and management concepts.
- increase your competitive edge by learning what is essential versus interesting.
- work with state-of-the-art management software.
- gain "hands-on" technical experience with exceptional indoor and outdoor facilities.
- experience a comprehensive, intensive course structure that substantially improves technical expertise.

Basic Soil, Plant, & Water Relationships July 31, 2018
Soil texture and structure, water holding capacity, retention, intake rates, evaporation, transpiration, soil classification, measurement of soil moisture and tension
Irrigation Scheduling, Salinity, & Drainage August 1-2, 2018
(Suggested prerequisite: Basic Soil, Plant & Water Relationships)
ETo and crop coefficients, practical irrigation scheduling, how efficiency and uniformity influence scheduling, drainage concepts and layouts, salinity, leaching reqeuirements, reclamation.
Fertigation March 5, 2018 and August 13, 2018
The class will cover new techniques in the control and application of fertilizers through irrigation systems and strategies to conform with the intent of the new nitrogen regulations in California. Other topics will include nitrogen fertilizers, challenges with phosphorus and potassium applications, growth enhancers, and organic-compliant ways to keep drip systems clean. Increasing yields per acre-foot of evapotranspiration (ET) through better fertility management, will also be discussed.
Row Crop Drip Irrigation August 14, 2018
Design layouts, flushing, fittings, how design relates to management, hose installation, retrieval
Drip/Micro Irrigation Design August 15-17, 2018
(Suggested prerequisites: Basic Soil, Plant, & Water Relationships, Basic Hydraulics I & II, Pumps I)
Topics will include: filtration, step-by-step design procedure of hardware selection and hyraulics, drip/micro system design, SDI for trees and vines, plugging prevention. Features ITRC book Drip and Micro Irrigation for Trees, Vines, and Field Crops (4th Ed.) and software, Drip Hydraulics.
Topics will include: the unique aspects of proper irrigation timing with these irrigation methods; how to control the amount of water that infiltrates; reducing losses; tailwater return systems; pressures, sprinkler types, and spacings for sprinklers; how to get a uniform irrigation with all the methods; modifying infiltration rates; common possibilities for improving efficiencies (along with their limitations).

Landscape Sprinkler Design TBD
Hybrid course covers irrigation system components, soil/plant/water relationships, distribution uniformity, application rates, sprinkler placement & selection, and irrigation scheduling. Online portion will cover necessary prerequisites in preparation of a 2-day design example in class. The 2-day class at Cal Poly is optional.
Landscape Irrigation Auditor TBD$295
(Suggested prerequisites: Basic Soil, Plant, & Water Relationships, Basic Pipeline Hydraulics I & II)
Steps performed in an audit to determine distribution uniformity (DU) including site inspection and tune-up, system test, calculating system performance and using performance values to schedule irrigations. An irrigation audit will be conducted in class.
