MicroEssentials® S15® vs. MAP Blend


Evaluate the yield response of canola to MicroEssentials® S15® (13-33-0-15S) compared to MAP (11-52-0) + AS (21-0-0-24S) and MAP.


  • Proper applications of phosphorus (P) and sulfur (S) are critical for optimum canola yields.

  • A blend of MAP + AS (ammonium sulfate) is commonly used as a primary fertilizer source in canola-growing regions of North America.

  • MicroEssentials® S15® is a proprietary fertilizer that combines nitrogen (N), P and S fused into one nutritionally balanced granule.
