Some time ago it was observed that humic products affect plant root and shoot growth and yield. In order to better understand these natural compounds a USDA team in Iowa has been conducting disciplined field trials using these materials. This talk updates attendees on the past years of research on humic products’ effects on Midwestern corn and soils. Measures of in-season plant growth and harvest yield have indicated significant effects of the humic products compared to control treatments.
