Sidedressing nitrogen: What should growers keep in mind when applying in-season?

In the 4th episode of the Advancing Nitrogen Smart series, we’re talking in-depth about sidedress. What are the growth stages critical to growers when sidedressing? What are options for assessing whether to add supplemental N, and how should they be used? How do wet conditions affect yield, and are rescue treatments economically advantageous? What sensing methods are available (such as drones) and what are their pros and cons?
