Agronomy Tip: Plan for In-Season Fertility and Tissue Sampling
Ryan Moeller, Technical Seed Agronomist with WinField United, recommends tissue sampling in-season and making any micronutrient applications or side dressing as necessary. “What we find in early Spring through V10, or the grand growth phase, is usually manganese, zinc, and boron that are the most efficient micronutrients,” says Moeller.
The ideal stage to start tissue sampling is five leaf corn because at V6, corn starts building the ear. Understanding what the crop needs and prioritizing any applications on your most productive acres may take precedence over other tasks.
