In my soybean research at the Agronology 10 Research Center, we are producing two more bushels of soybeans per acre with a 1.3 lbs./ Mn (manganese) application. This manganese is applied in our fall, dribble band fertilizer application. We are netting approximately 19.50/A with $12.00 soybeans over the last four years with this treatment.
Additionally, I have found an interesting happening in the “Critical Considerations” group, which is the top yielding 24 corn plots each year. In 2012, half of the 24 plots had a manganese application (1.3 lbs. Mn/A) applied in the previous year’s soybean fertility program.
