Early planting of corn combined with increased residue cover, due to conservation tillage, often results in cooler and wetter spring planting conditions. These conditions can reduce secondary and micronutrient availability in soils, and may result in nutrient deficiencies in young corn plants.
Sulfur (S) and zinc (Zn) are two nutrients that may be limiting in corn-on-soybean rotations or during cool and wet spring soil conditions. This research project attempted to fill in the knowledge gap regarding the effects of Zn and S fertilizer in southern Minnesota and answer some of the following questions:
