The Value of a N Mgt. System.
• N must move into plant with soil water
• When it rains crop N uptake can be shallow
• When it doesn’t rain crop N uptake deeper
• When applied early risk of loss higher
• When applied late risk of no rain greater

Doing the Math - 2011
• 17 Bu/A x $6/Bu = $102/A
• Less Cost of N: $50/A = $52/A
• $52/A x 1200 acres = $62,400
• $62,400 x 3 = $187,200
• What will it be in 2012?
