Abstract:Highly‐weathered soils have low native fertility; thus, optimum nutrient management is critical, especially for a high‐input crop such as corn (Zea mays). Field studies were established in Plains and Tifton, GA (USA) to assess secondary nutrient (SN; Mg, Ca, and S) and micronutrient (MN; B, Zn, Mn, Fe, Cu, and Mo) application effects on corn fertilized with primary nutrients (PN; N, P, and K) to achieve 12.5 Mg ha−1 (low) and 25.1 Mg ha−1 (high) yields. Both Plains and Tifton have Ultisol soil. However, the Ti… Show more
