As corn grows, water loss through evapotranspiration (ET) drives both cooling and nutrient movement. Our latest blog post explains how ET shifts from soil evaporation early to plant transpiration later, why peak demand occurs around tasseling and silking, and how water stress at key growth stages reduces yield. Understanding ET timing helps optimize irrigation for stronger roots, better nutrient uptake, and higher yields.

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.
