Nitrogen-deficient corn is viably lighter than healthy corn seedlings.
Between the V3 and V5 growth stages, corn transitions from deriving energy directly from the
seed to acquiring energy from sunlight through photosynthesis. Visual appearances during
these stages offer clues to overall plant health.
During early corn growth, environmental conditions have a huge impact on root systems and their ability to take up nutrients, sometimes leading
growers to think their crops have a nutrient deficiency. When deficiency symptoms appear, take time to evaluate the cause. Plants often outgrow
early season symptoms as the soils warm and microbial activity releases additional nutrients. Early and correct diagnosis of problems allows
producers to manage accordingly.
