2020 FREP Conference

Annual FREP/WPHA 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 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 2020 FREP/WPHA Nutrient Management Conference will be held on October 27-29 in Modesto, California.

Call for Posters

A poster session will be held on October 29, after the conference presentations. Posters must have scientific subject matter relevant to the efficient use of fertilizing materials in California conditions, such as climate, crops, and soils. Posters should describe scientific projects that emphasize improved nutrient and irrigation management practices in California agriculture. Anyone, whether funded by FREP or other entities, may submit an abstract.
If you would like to present a poster, submit your abstract to FREP@cdfa.ca.gov by October 21, 2019. Submissions must include poster title, author names and affiliations, and an abstract that is no more than 350 words. One presenter per poster will receive free conference registration.
We encourage preparing the abstracts according to the American Society of Agronomy Tips for Writing Abstracts. To learn more about poster preparation, evaluation criteria, time and location of the poster session, please see Poster Guidelines and Session Details.

Poster Competition: This year, there will be student poster competitions for two categories: undergraduate and graduate students. Posters will be evaluated by judges, and top presentations will receive awards in each category. Prizes include $200 (1st), $150 (2nd), and $100 (3rd). If you are planning to participate in the poster competition, please indicate your intent in your email and whether you are a current graduate or undergraduate student.


The Proceedings include a synopsis of FREP’s latest achievements, summaries of current FREP-funded projects and relevant research, and a list of completed FREP projects. See past Conference Proceedings.
