What are the safe limits for corn when placing fertilizer with seed?

The safe limits for placing fertilizer with corn seed are typically around a 5 cm x 5 cm band. This distance helps to ensure that the fertilizer is close enough to promote early plant growth without risking damage to the emerging seedlings. Fertilizers contain nutrients that are vital for corn development, but if placed too close to the seed, they can cause injury due to salt concentrations or ammonia toxicity. The 5 cm x 5 cm spacing strikes a balance, allowing the seedlings to access nutrients while minimizing the risk of harm, particularly during the critical early stages of growth when the plant is sensitive.
