Ken Ferrie explains why fertility is the foundation for the Systems Approach pyramid and key to increasing corn yields.
In episode 4 of Corn College TV, Ken Ferrie encourages farmers to start off their crop year on the right foot, and that includes fertility management.
“The challenge with nitrogen management is that it is dependent on the environment, which can be unpredictable,” he says. “But we can still use an educated guess to determine our nitrogen rates, timing and placements.”
In the spring, as the ground temperatures warm, microbes become more active and immobilize nitrogen, making it unavailable to the corn plant.
“You want to have enough nitrogen available to the plant at the right times,” Ferrie says. “And even with the immobilization period, you can’t stop it from happening but you can shorten the time window.”
Ferrie says that if you routinely fight keeping corn green, it’s time to adjust your nitrogen program. This including timing and placement of nitrogen.
