How many tons of nitrogen (N) per bushel of planned yield corn should be recommended?

The recommendation of 1 ton of nitrogen (N) per bushel of planned yield corn reflects established agricultural guidelines for optimizing corn production while minimizing environmental impact. Research shows that a nitrogen application rate around this level aligns with the needs of the corn crop during the growing season, providing sufficient nutrients for optimal growth and grain fill.

When managing nutrient application, especially nitrogen, it is crucial to base recommendations on average yield expectations and ensure that plants have the necessary nutrients at critical growth stages. This balance helps achieve maximum productivity without excessive nitrogen application, which could lead to nutrient runoff and soil degradation.

The other figures presented in the choices suggest higher application rates, which may lead to diminishing returns in corn growth and increased risk of nutrient leaching into waterways, thus deteriorating water quality. The guideline of 1 ton of nitrogen per bushel maintains this essential balance, emphasizing both yield optimization and environmental stewardship.
