Success StoryUnderstanding and Choosing the Right Nitrogen Loss Inhibitor for Corn Production



Understanding and Choosing the Right Nitrogen Loss Inhibitor for Corn Production

Author: John Grove

Planning Unit: Plant and Soil Sciences

Major Program: Grains

Outcome: Long-Term Outcome

Answered a March phone call from a corn grower who was pre-purchasing nitrogen fertilizer. Also wanted to early purchase nitrogen loss inhibitors but was confused as to what product(s) to buy. We discussed his fields (topography, drainage, irrigation), soils (texture, tilth, wetness potential, organic matter), usual corn management (planting date, row spacing, hybrid maturity, seeding rate) and usual nitrogen management (rate, fertilizer sources, timing, placement). It turns out that he was intending to purchase urease/volatilization inhibitors when his most likely mode of N loss, denitrification, could only be reduced by use of a nitrification inhibitor. Our conversation resulted in his having a much better understanding of the class of nitrogen loss inhibitor products that he needed for his corn fields/soils. He told me that the phone call was worth $30,000 to him - 2,000 acres at $15 per acre in wrong product cost. And we didn't even discuss the amount of corn yield loss that might also have resulted due to use of the wrong inhibitor.
