    MicroEssentials® S10® Soybean Study – AgriFacts

    2.5 BU/AC

    Increased yield with MicroEssentials S10 over MAP

    1.4 BU/AC

    Objective

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

    OVERVIEW

    • 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.


    TRIAL DETAILS

    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.

    TREATMENTS:

    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


    RESULTS


    SUMMARY

    • 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.
