I have been using SumaGroulx for the past 4 years now, but this year was the first that I used it on winter wheat. I applied SumaGroulx in early spring and had a 13% yield increase. I reduced my application of nitrogen to almost nothing. I will apply SumaGroulx this fall to help reduce residue and am expecting a 20% increase for my wheat in Summer 2013 by applying this way. My soybeans have more and larger pods even in poor, sandy soil and the bean itself is taller and has pods all the way to the top of the plant. I also grow soybeans, sugar beets, and black beans.
