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.
Crop: Corn (Zea mays)
Locations: 47 trials across the US and Canada – IA, IL, IN, KS, KY, MB, MI, MN, MO, MS, ND, NE, OH, ON, SC, SD, WI
Data Source: Field studies conducted by independent third-party researchers.

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.
