How much fertilizer do I need for 1 acre of corn?
For corn, if the fertility level is good, a small amount of fertilizer (about 100 pounds of starter per acre) will provide an adequate starter response. Do not apply more than 70 pounds of N + K2O per acre if the fertilizer is placed approximately 2 inches away from the seed.
What is the best fertilizer ratio for corn?
Pre-planting fertilizers for corn should have NPK ratios of 1-4-0, 1-3-1, 1-3-3, or 1-1-1 to ensure they don’t contain too much nitrogen.
