Timing nitrogen efficiently: How to maximize yield while mitigating risk

In the 8th episode of the Advancing Nitrogen Smart series, we’re taking about timing. What makes understanding timing so important to using nitrogen efficiently? Should growers apply in fall, and if so, what source should be avoided? Between which growth stages does corn take up the bulk of a field's N? What do weather extremes teach us about optimal timing? Do some timing decisions negatively affect farmers' finances? In what ways?
