In a deep-dive episode of Crop Cast, host Sean Nettleton sat down with Dr. Richard Mulvaney of the University of Illinois to challenge long-held assumptions about nitrogen (N) management. If you're still basing fertilizer decisions on yield goals alone, it's time to rethink how you're managing one of the most critical and expensive crop inputs.

Another agronomy deep-dive brought to you by Crop Cast. In Episode 38, host Sean Nettleton along with Jason Schley and Jaren Schley takes us beyond the basics and into the underground world of roots—specifically, the nodal roots that form during the V4 to V6 stages of corn development. This period marks a major physiological transition in the plant’s life, and the insights shared in this episode are essential listening for anyone who’s serious about maximizing yield potential. Let’s unpack the episode—and dig deeper (pun intended) into why nodal root development during this stage is such a game-changer.
