    Objective

    Evaluate sugar beet yield and RSA (Recoverable Sugar per Acre) response to MAP (11-52-0), MAP + APP (10-34-0), and MicroEssentials® SZ® (12-40-0-10S-1Zn) + APP.

    Overview

    • MAP and MOP are commonly used as primary phosphate and potash sources in sugar beet-growing regions of North America.
    • In lower soil test phosphorus situations, a liquid starter of APP (Ammonium Poly Phosphate [10-34-0]) may be recommended in addition to fall MAP applications.
    • University research will often discourage the use of secondary or micronutrient sources in sugar beet production.
    • MicroEssentials® SZ® is a performance phosphate source that supplies multiple nutrients fused into one nutritionally balanced granule, providing uniform nutrient distribution, increased nutrient uptake, and season-long S availability.

    Trial Details

    Locations and Crop Management:

    CROP: Sugar beet (Beta vulgaris)

    YEARS: 2018-2019

    LOCATIONS: 6 trials conducted in MN and MI

    DATA SOURCE: Field studies conducted by third- party, independent researchers.

    EXPERIMENTAL DESIGN: Small-plot RCBD with 4 replications.

    CROPPING CONDITIONS:

    Application Rates, Timing, and Method

    P Rate: 40 lbs P₂O₅ /ac applied in the Fall as either MAP or MicroEssentials® SZ®.

    K Rate: 40 lbs K₂O /ac (MN) and 180 lbs K₂O /ac (MI) applied in the Fall as MOP.

    S Rate: 10 lbs S/ac applied from MicroEssentials® SZ®.

    Zn Rate: 1 lbs Zn/ac applied from MicroEssentials® SZ®.

    Liquid Starter: 3 gal/ac as 10-34-0 applied at planting.



    Summary

    • Along with fall applications of MAP, liquid APP starter (10-34-0) at planting increased total yield by 0.4 ton/ac and RSA by 44 lbs/ac.
    • Replacing MAP with MicroEssentials® SZ® resulted in a yield increase of +1.5 ton/ac and +450 lbs/ac of RSA.
    • The addition of S and Zn provided by MicroEssentials® SZ® boosted total tonnage and recoverable sugar, indicating the benefits of secondary macronutrients and micronutrients in sugar beet production.
