2017 FREP Conference

Annual FREP/WHPA Conference

For 25 years, FREP has presented its pioneering fertilizer research at annual conferences. Since 2007, FREP has collaborated with the Western Plant Health Association (WPHA) 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 2018 conference will on October 23-24 in Seaside, California. If you would like to be notified when the 2018 agenda and registration are available, email with your preferred email address and/or mailing address.
