An Evaluation of Corn Responses to SuperCal 98G
and Nitrogen in Cedar Falls, Iowa in 2001

98G was applied at a rate of 200 lbs/A
Although there was no significant difference in yield with SuperCal 98G versus the control, at 160 lbs of N, there is a 10-bushel advantage. At an average cost of $17 for 200lbs of 98G applied that is a significant return of investment.
