MicroEssentials® S15® Durum Wheat Fertility


Evaluate the yield response of MicroEssentials® S15® (13-33-0-15S) in durum wheat compared to MAP (11-52-0).


  • Durum wheat is a common crop grown in the Northern Great Plains and Western Prairie Provinces of Canada.

  • MAP is commonly used as a phosphorus fertilizer source applied to durum wheat.

  • In wheat, sulfur and nitrogen are needed in a proper balance for desirable milling and baking qualities.

  • MicroEssentials® S15® provides N, P and S in one nutritionally balanced granule.

Yield MicroEssentials S15 vs MAP

Sulfur deficiency in wheat


  • Averaged across 3 years and 12 replicated trials, MicroEssentials® S15® outyielded MAP by 1.2 bu/ac.

  • This data demonstrated a statistically significant yield response to the sulfur in MicroEssentials® S15®.

  • MicroEssentials® S15® provides uniform nutrient distribution, increased phosphorus uptake and season-long sulfur availability for additional yield and return on investment.
