We have notice sulfur test levels going lower and lower each year.  For the past 2 years, Dr. Fernadez at University of Illinois has been researching crop response to Sulfur.  He has found as much as a 50 bushel response to sulfur.  If you have not looked at it, you probably need to find out your sulfur levels in your soil.  Some common sources of sulfur are Ammonium Sulfate, elemental sulfur, and gypsum.  15 ppm is thought to be the critical level.
