Management Tips for Soybeans

Tip #1 I would strongly recommend that you consider adding 10 lbs. s/a to the fall dribble band fertilizer application. Our normal P&K recommendation for 60 bu/a soybeans would be a 17-40-80. Over a thirteen year time period (2001-2013), the addition of 10 lbs of sulfur enhanced yields by an average 2.2 bu/a per year. With soybeans…
