Abstract

Fertilizer nutrient requirements for corn are based on expected yield and nutrient levels in the soil. Nitrogen is the nutrient most often required for growing corn. Nearly all corn in Nebraska will need some nitrogen fertilizer unless there is substantial nitrogen in the soil from sources. Phorphorus is the second nutrient most likely to be needed, and needs are best determined with a reliable soil test. Potassium, sulfur, zinc, and iron fertilizer may be needed for growing corn on certain soils. Crop needs for calcium, magnesium, boron, chlorine, copper, manganese, and molybdenum are adequately supplied by Nebraska soils.
