When Bob Recker sees odd patterns in cornfields from the air as he flies across farmland in northeastern Iowa, he can’t wait to land and investigate up close. As owner of Cedar Valley Innovation, Waterloo, Iowa, he uses digital and GPS technologies, along with well honed engineering analytical skills to identify yield-loss problems.
Tim Dritz didn’t hesitate to drive 350 miles from his western Minnesota farm for a day and a half August meeting in Waterloo, Iowa. Neither did Charlie Hammer from Beaver Dam, Wisc., whose drive was about 250 miles one-way. The veteran strip-tillers didn’t mind because they were going to a peer meeting they valued – in meetings and online. They met on an invitation-only Facebook page dedicated to strip-till, which quickly branched out to technologic ways to boost agronomic efficiency, says Loran Steinlage, one of the group’s early members.
Your choice of nitrogen (N) comes down to when you apply, your equipment, handling preferences, availability and costs. And the weather wild card often determines whether you’re happy with your choice in any given year.
Nitrogen management is entirely about risk management, especially this year. “There’s an economic risk of wasting money and being seen as environmentally reckless by applying too much N, and a risk of corn yield loss from applying too little,” says Dan Frieberg, president of Premier Crop Systems, LLC, in West Des Moines, Iowa. “But there’s also a risk that’s not talked about much — allowing nitrogen-management decisions to adversely affect other crop-production operations.”
