The study looked at 19 different combinations of nitrogen sources, timing and placements and compared the yield advantage of each form, where SUPERU ranked no. 1.
SUPERU is a granular urea fertilizer that uniformly incorporates both a urease and nitrification inhibitor to provide protection against all three forms of nitrogen loss – providing growers with a peace of mind when it comes to their nitrogen investment.
