MicroEssentials® S10® — Corn Study


Evaluate the yield response of corn to MAP (11-52-0) and MicroEssentials® S10® (12-40-0-10S).


  • Monoammonium phosphate (MAP) is a common phosphorus (P) source used on corn.

  • Adequate availability of sulfur (S) during vegetative and reproductive growth is critical for maximum corn yield.

  • MicroEssentials® S10® supplies multiple nutrients fused into one nutritionally balanced granule, promoting uniform nutrient distribution, increased nutrient uptake, season-long S availability and higher yields.

Application Timing: Spring Preplant

Application Method: Broadcast incorporated


Corn Yield Response


  • MicroEssentials® S10® increased corn yield by 4.7 bu/ac over MAP across 47 trials in 17 states/provinces.

  • Higher corn yields achieved by using MicroEssentials® S10® demonstrates the value of uniform nutrient distribution, increased nutrient uptake, and season-long S availability.

Individual results may vary, and performance may vary from location to location and from year to year. This result may not be an indicator of results you may obtain as local growing, soil and weather conditions may vary. Growers should evaluate data from multiple locations and years whenever possible.
