A potential “Super El Niño” in 2026 could bring major shifts for growers, from drought relief to excess rainfall, saturated soils, nitrogen loss, and higher disease pressure. With weather patterns expected to change through summer and winter, flexible nitrogen and water management will be critical. Sentinel’s All-N and Nave’s Hydroflow help farmers model scenarios, monitor field impacts, and adjust decisions in real time.

As corn gets established, early nitrogen and water needs remain low. Seedlings rely mostly on moisture for germination and nutrients stored in the kernel. Too much water or nitrogen too soon can stunt roots, create anaerobic conditions, and increase nitrogen loss. Maintaining a balanced “Goldilocks” environment supports root growth, beneficial biology, and better timing for inputs as corn approaches V6.

Spring 2026 is showing sharp contrasts across the Missouri River. Nebraska’s corn is being planted into very dry soils, raising concerns about germination, irrigation timing, and nitrogen volatilization. In Iowa, wet conditions increase the risk of sidewall compaction, emergence problems, and nitrogen loss. Whether managing water or nitrogen, growers need timely guidance to protect yield potential.
