MicroEssentials® SZ® vs. DAP Blend


Evaluate the yield response of corn to MicroEssentials® SZ® (12-40-0-10S-1Zn) compared to DAP (18-46-0) + AS (21-0-0-24S) + ZnSO₄ (0-0-0-16S-36Zn).


  • Balanced crop nutrition is critical for corn production.

  • MicroEssentials® SZ® supplies nitrogen (N), phosphorus (P), sulfur (S) and zinc (Zn) in one nutritionally balanced granule.

  • The MicroEssentials® proprietary Fusion® technology process creates a unique chemistry that results in increased nutrient uptake and crop yield compared to alternative sources.
