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

• 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

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.”
