At a time when farm margins are extremely tight, variable-rate nitrogen application can save producers money and maximize yields. Producers can evaluate past yield history for a field along with analysis of soil types, rainfall and geography to dial in the nitrogen they need, says Stacie Buhr, a certified service provider for DuPont Pioneer’s Encirca Services.
“In one piece of the field, we may have a yield target of 250 bu., but we may have a sand pocket or a peat bog that may only yield 150 bu.,” Buhr tells Iowa producer Chris Barron of Ag View Solutions in a recent “Margin Minute” video on AgWeb.com. “Why are we applying nitrogen to 250-bu. corn if we know it’s only going to yield 150 bu.? With that in mind, we can save producers a ton of money and really go to their bottom line and manage their cost and overall productivity.”
This is a case where it can make sense to cut back on inputs.
“Let’s put the bang for the buck where we need it and reduce our inputs where we know we’re not going to get the yield,” Buhr says.
