There’s no better, one-size-fits-all recommendation for fertilizing corn (Zea mays) that matches all soil conditions. Some soils contain plant nutrients. The means to ascertain fertilizing needs would be to get your soil tested. There are a few general recommendations that are applicable to nitrogen-loving corn. Water-soluble granular fertilizer is recommended.
Corn is an annual which will rise in U.S. Department of Agriculture plant hardiness zones 2 through 11. Corn is wind pollinated, so it’s better for the home gardener to plant three or four rows of corn in a plants in circle or a hill rather than a row. Should you fertilize in a squarefoot, hill or circle mulch recommendations in feet are more helpful than those for duration of row. After you apply fertilizer always water the dirt.
Fertilizing Before Planting
If you do not have your soil tested, operate 6 pounds of water fertilizer before you plant the seed. If you are calculating by square feet of garden, operate 2-3 pounds of 10-10-10 fertilizer 3 to 4 inches deep to each 100 square feet before planting corn. Until or plow 25 pounds of 10-10-10 fertilizer to the upper 6 inches of 1,000 square feet.
Fertilizing Young Corn
When your plants have grown four or five fully expanded leaves, apply 1/2 into 3/4 pounds of 10-10-10 fertilizer no closer than two inches from the bottom of the plants and then rake it
Fertilizing Maturing Corn
Corn needs a lot of nitrogen. Pale green leaves indicate a lack of nitrogen in corn. Add 1/2 pound of urea, 46-0-0 mulch, to each 100 square feet of dirt when corn plants have eight to 10 leaves. Scatter the fertilizer 6 inches in the sides of the plants and water it in the soil. Repeat this with 3/4 pound of urea as soon as your plants grow. Another way to deal with the nitrogen need of corn would be to add 1 1/2 pounds of ammonium nitrate, 34-0-0 once the plants are 8 to 12 inches tall. Sprinkle this at least two inches from the bottom of the plants and then rake it two inches deep.
