Nitrogen Uptake In Corn
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

Based on 30 years of university research showing that using nitrapyrin,
the active ingredient of Instinct® and N-Serve ®, can result in additional yield.
Adoption of N Mgt Systems GROWMARK, 2011
• 30 sites
• 2 to 3 applications of N
• 50 to 90 lbs
• Nearly all have a post-emerge application
• N enhancements commonly used

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?
FACT #3 Nitrogen Management is a System, Not Just an Application
“The only way of finding the limits of the possible is by going beyond
them into the impossible.”
