MicroEssentials® S10® — Soybean Study


Evaluate the yield response of soybean to MAP (11-52-0), MAP + AS (21-0-0-24S), and MicroEssentials® S10® (12-40-0-10S).


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

  • New university research highlights the need for sulfur (S) management on soybean due to higher grain yields and lower atmospheric deposition. Data also emphasizes the need for S during both vegetative and reproductive growth (See Figure 1).

  • 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.

Cropping Conditions: All trials conformed to local cropping practices.

P Rate: 40 lbs P₂O₅/ac applied as MAP (11-52-0), MAP+AS (21-0-0-24) or MicroEssentials® S10® (12-40-0-10S)

S Rate: 10 lbs S/ac from AS or MicroEssentials® S10®

K Rate: As required by soil test

Application Timing: Spring Preplant

Application Method: Broadcast incorporated


Soybean Yield Response


  • Soybean yields increased with the addition of S.

  • Averaged across 22 site-years, MicroEssentials® S10® increased soybean yield by 1.8 bu/ac over MAP and 1.4 bu/ac over MAP+AS.

  • This research demonstrates the additional soybean yield from applying a superior phosphate source that contains two forms of S (sulfate and elemental).

  • 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.
