MicroEssentials® S10® Soybean Study


Evaluate soybean yield response 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 in soybean production.

  • New university research highlights the need for sulfur (S) management in soybean due to higher grain yields and lower atmospheric deposition. Data also emphasize 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.

MicroEssentials S10 Soybean Study


Crop: Soybean (Glycine max)

Years: 2018-2020

Locations: 21 trials - AR, IL, MI, OH, ON, TN, WI

Data Source: Field studies conducted by independent, third-party researchers.

Experimental Design: Small-plot RCBD with 4 replications.

Cropping Conditions: All trials conformed to local cropping practices.


Treatment (Trmnt) / Rates / Timing:

  1. P Rate: 40 lbs P₂O₅/ac applied as MAP or MicroEssentials S10

  2. K Rate: 60 lbs K₂O/ac applied accross all treatments

  3. S Rate: 10 lbs S/ac applied as AS or MicroEssentials S10

  4. Application Timing: Spring Preplant

Application Method: Broadcast Incorporated


MicroEssentials® S10® Soybean Study


  • Soybean yield increased with the addition of S.

  • Averaged across 21 site-years, MicroEssentials S10 increased soybean yield 2.5 bu/ac over MAP and 1.4 bu/ac over MAP + AS.

  • MicroEssentials S10 demonstrates the value of uniform nutrient distribution, increased nutrient uptake, and two forms of S (sulfate and elemental) for season-long S availability.
