In every episode of Corn College TV, the Farm Journal Field Agronomists tackle a farmer’s question from the field. In episode 6, the team answers a question about nitrogen application timing and potential loss.

With an early harvest and warm weather through the fall, strip-tillers welcomed the cooperative weather. But, many were asking when is the right time to hook up the tanks and apply nitrogen when building strips that early?

“We’re on the right track in building the strips when the soil conditions are fit,” says Farm Journal Field Agronomist Ken Ferrie. “But this fall, in September when many were heading to the field, they realized it was too warm to apply nitrogen with that pass.”

“In these types of conditions, build the strip without nitrogen and return in the spring to apply the nitrogen,” he says.
