On Farm Research

As active members of Practical Farmers of Iowa (PFI), we regularly participate in on farm research trials. In 2008 and 2009 with support from Susana Goggi, ISU Associate Professor in Seed Physiology and Rick Exner, PFI consultant we ran trials using Organic Seed Treatments.


PFI report follows:
Testing in the lab has shown that certain plant-derived oils can inhibit seed-pathogenic fungi. Susan Jutz and Norm McCoy compared peas treated with and without essential oils treatments. Susan also included in her trial seed treated with the commercial product Natural II. Ron Dunphy and Ken Choquette compared soybeans treated with and without the essential oils.

Among the results in the first year, essential oils seed treatment at Susan Jutz’s farm significantly increased pea seedling emergence, and Natural II resulted in significantly greater emergence than either the control or the essential oils treatment.
