Corn has only one strict requirement: High nitrogen. This will mean the the soil will be slightly acidic, and contain high amounts of nitrogen. Any high nitrogen fertilizer with no potassium and phosphorus will be needed, as well as applied again throughout the season. Corn are heavy feeders, and will require constant feeding.
