Sweet corn is a fast-growing vegetable that is usually low-maintenance when it comes to fertilizer. Fertilizer helps raise the level of nutrients in the soil to harbor a beneficial growing environment for corn. Corn enjoys a nitrogen-rich soil environment with enough phosphorus. Growing well-fertilized corn involves attention to preparing the bed for the corn seeds and a keen eye to watch for signs of nutrient deficiency during growth.
Spread a 2-inch layer of compost over the area in which you will plant the corn.
Lightly sprinkle organic nitrogen fertilizer over the layer of compost.
Mix the compost and nitrogen fertilizer mix with the ground soil until the compost/soil mix is about 5 to 7 inches deep.
Plant the corn according to planting instructions for your strain of corn.
Fertilize the plants with a natural liquid corn fertilizer when the corn plants have reached a height of 4 inches. Fertilize the plants again when they are around 10 inches tall.
