Training For ITRC Certified Fertigator

Online class option coming soon!


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 – a key topic for California growers. Seating is available on a first come, first served basis.


An online Certified Fertigator course is currently under development and will soon be available to take for certification on your own time, at your own pace. A certificate of completion will be available for download for participants who pass the exam at the end of the course with a score of 70% or higher. Until then, feel free to utilize our fertigation video playlists on our YouTube channel, available in English and in Spanish.
