In July, 2003, Jonathan, a recent Ph.D. graduate from Utah State University, joined the newly formed Greenhouse Production Research Group (GPRG) of the USDA-ARS Application Technology Research Unit as a Research Horticulturist. As one of the original members of the GPRG group, and one of two scientists initially located at the University of Toledo worksite, Dr. Frantz has contributed tremendously to the development and progress of the GPRG. However, his time with us has come to an end as he recently accepted a position effective January 2013 with DuPont Pioneer in Iowa as a Research Scientist.
Over the years Jonathan has researched plant nutrition including the use of silicon and its effects on plant stress as well as different nutritional and production issues of local and national floriculture growers. Other areas of research included hydrogels, alternative soilless media components, and the use of sensor technology in plant production. One of his most distinguished accomplishments with the GPRG is the innovation of Virtual Grower, a software program that brings together several existing models to assist greenhouse users predict heating and energy use specific to their location, greenhouse design, crop produced, and management preferences.
During his nine years with USDA-ARS, Jonathan has received numerous awards, been a member of several local and national associations, dedicated service to different organizations, invited as speaker/presenter at different locations around the country and the world, received and collaborated on different grant projects, and has published an abundance of articles and in peer-reviewed journals numerous trade articles and books.
Jonathan says, "We have done a lot of good things, I think, in our time here. The industry has been very good to us and I hope we've responded in kind to them. It's never easy leaving a place, especially when it is full of good people and good times. I'll miss the team in Toledo!"
Dr. Frantz will be greatly missed by the entire GPRG team and we extend to him and his family best wishes in all his endeavors.
