FREP/WPH Nutrient Management Conference

Fertilizer Research and Education Program

For over 25 years, FREP has presented its pioneering fertilizer research at annual conferences. Since 2007, FREP has collaborated with the Western Plant Health (WPH) to create a conference that balances technical research with discussion on practical application. Presenters from academia, industry, and agricultural consulting provide general and technical information, current research and data, and practical applications addressing statewide and regional nutrient management issues.

The 2022 FREP/WPH Conference will be held in Visalia, CA, on October 26 and 27, 2022. Registration now open!
