This service intends to provide timely and unbiased information on these products for farmers. In 2015, we tested submitted products from the following companies:AgZyme® by Ag ConceptsBAM-FX by Zero Gravity SolutionsMethods: Corn and soybean trials were planted at three sites on Ohio State University Research Farms: 1) Clark County at the Western Agricultural Research Station in S. Charleston, 2) Wayne County at the Ohio Agricultural Research and Development Center in Wooster, 3) Wood County at the Northwest Agricultural Research Station in Custar.Data collected include: 1) Complete soil sample analysis prior to planting, 2) Emergence counts at V5 for corn and soybean, 3) Whole plant sampling at V5 for total biomass and complete nutrient analysis, 4) Leaf sampling at R1 for corn and soybean for complete nutrient analysis, 5) Final stand counts at maturity for corn, and 6) Harvest grain yield with complete grain nutrient analysis.Results: Across all three sites, no consistent trends were found with any of the tested products. No products significantly affected a measured property at more than 1 site. For both corn and soybean, no product treatment yielded significantly greater grain than the control. This was only one year of field data, so interpretations should be made with caution, especially considering the dry weather encountered in the 2016 field season.The summary report can be found here: go.osu.edu/SAFAFor 2017, we have adjusted our pricing for this service, collecting less data but hopefully making the service more affordable to vendors and retailers.
