As we move into 2026, we want to kick off a year of informative blog posts to help guide water and nitrogen management for producers. At Sentinel Ag we are dedicated to bringing real solutions to the industry for optimal nitrogen management and now water management. Profitability is achievable and we have the tools to get you there. Check out our blog to find helpful information and insights throughout the year and check out our other resources to stay up to date!

Maximizing corn yield depends on a strong “solar collection system” of healthy upper canopy leaves and sufficient nitrogen during reproduction. Research shows upper leaves drive 80–90% of photosynthesis, while lower leaves serve as nutrient reserves. Effective nitrogen management—especially during grain fill—helps prevent stress, maintain kernel weight, and protect yield potential.

A little stress at the right time can actually help corn grow stronger. Early-season water limits encourage deeper roots, letting plants reach more nutrients and moisture. Waiting on some nitrogen pushes corn to tap natural soil nitrogen first. Done carefully—avoiding stress during key growth stages—this approach can boost yields and make crops more resilient to challenges later in the season.
