    Objective

    Quantify the increase of phosphorus uptake with MicroEssentials® SZ® (12-40-0-10S-1Zn) applied to corn compared to DAP-based blends that supply the same rate of nitrogen, phosphorus, sulfur and zinc.

    OVERVIEW

    • Balanced crop nutrition is critical for corn production.
    • MicroEssentials® SZ® supplies nitrogen, phosphorus, sulfur and zinc in one nutritionally-balanced granule.
    • The MicroEssentials® proprietary Fusion® technology process creates a unique chemistry that results in increased nutrient uptake and crop yield compared to alternative sources.

    TRIAL DETAILS

    Crop: Corn (Zea mays)

    Year: 2013

    Location: Sabanci University, Turkey

    Data Source: Dr. Ismail Cakmak

    Experimental Design: Pot trials conducted under greenhouse conditions on a clay loam soil.

    Cropping Conditions:

    Treatments: MicroEssentials® SZ®, DAP + AS + ZnSO₄, DAP + AS, DAP

    Study Details: All sulfur in the blend was supplied in the sulfate form.
    Fertilizers were homogeneously mixed with the soil, simulating broadcast incorporation.
    Corn above-ground dry matter and nutrient uptake were determined 20 days after planting.


    RESULTS


    SUMMARY

    • Corn phosphorus uptake was significantly higher for MicroEssentials® SZ® than any other treatment.
    • MicroEssentials® SZ® increased P uptake by 28% compared to the DAP + AS + ZnSO₄ blend.
    • MicroEssentials® SZ® resulted in a 100% phosphorus uptake increase compared to DAP and the DAP + AS blend.
    • Through the MicroEssentials® proprietary Fusion® manufacturing process, nitrogen, phosphorus, sulfur and zinc are combined into one nutritionally balanced granule—creating a single source for balanced crop nutrition.
    • The unique formulation of MicroEssentials® SZ® increases phosphorus uptake.
