The key to success with your corn crop is fertilization. Corn requires large amounts of nitrogen throughout the season and phosphorus is crucial during corn's development. After you've fertilized the bed at planting, foliar applications, once the seedlings get growing, can boost yields, according to Denny Eilers in the Corn & Soybean Digest. Apply the first foliar feeding when the corn plants are 4 to 6 inches tall. Spray the corn in the early morning or late evening hours and during a period of time when there will be no rain.
Things You'll Need
- Liquid organic corn fertilizer
- Field sprayer or tank sprayer
- Turbo flood jet nozzle
Add 1 to 3 gallons per acre of liquid corn fertilizer to 30 to 75 gallons of water in the field sprayer. If you are fertilizing a backyard-grown corn, use a tank sprayer and mix the fertilizer and water according to label directions.
Adjust the nozzle on the tank sprayer to a fine mist. Use a turbo flood jet nozzle on the field sprayer, for a wide angle, flat spray.
Spray the corn with enough of the fertilizer solution to thoroughly cover all the foliage on each plant. Observe the plants as you spray and stop spraying when the fertilizer begins to run off the foliage.
Repeat the fertilizer application, in the same manner, when the corn reaches 10 to 12 inches tall and again when the plant is 18 to 24 inches tall. Allow at least 10 days between applications.
Tips & Warnings
- If you have any questions on how much fertilizer is required, contact your county cooperative extension agent.
