MicroEssentials® SZ® Phosphorus Uptake (Greenhouse Trial) vs MAP and MAP Blend in V6 Corn

Objective

Quantify the increase of phosphorus uptake with MicroEssentials® SZ® (12-40-0-10S-1Zn) applied
to corn compared to MAP (11-52-0) and MAP + Ammonium Sulfate (AS, 21-0-0-24S) + Zinc Sulfate (ZnSO₄ ,17.5-0-0-35.5Zn) blends in V6 corn.

OVERVIEW

  • Balanced crop nutrition is critical for corn production.

  • MicroEssentials SZ supplies nitrogen, phosphorus, sulfur, and zinc in one nutritionally balanced granule.

  • The MicroEssentials 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: 2023
LOCATION: Sabanci University, Turkey 
DATA SOURCE: Dr. Ismail Cakmak

EXPERIMENTAL DESIGN: Pot trials were conducted under greenhouse conditions and averaged across two soil types and two fertilizer rates:

  • Loam (7.9 pH, 4 ppm P, 0.1 ppm Zn) 

  • Sandy Clay Loam (7.8 pH, 13 ppm P, 0.2 ppm Zn)

  • Phosphorus fertilizer was applied representing a low and high P rate to each soil and balanced among fertilizer sources 

  • MAP + AS + ZnSO₄ blend was balanced to match phosphorus, sulfur, and zinc rates

TREATMENTS:

  • No phosphorus (UTC)

  • MAP + AS + ZnSO₄

  • MAP

  • MicroEssentials SZ

STUDY DETAILS:

  • Fertilizers were homogeneously mixed with soil, simulating broadcast and incorporated applications.

  • Above-ground dry matter and nutrient uptake was determined on 32-day-old/V6 corn.

RESULTS

MicroEssentials SZ vs. MAP Results

SUMMARY

  • Corn phosphorus uptake was greater with MicroEssentials SZ than any other treatment.

  • MicroEssentials SZ treated plants had 20% greater phosphorus uptake at V6 growth stage than plants treated with MAP.

  • MicroEssentials SZ treated plants had 9% greater phosphorus uptake at V6 growth stage than plants treated with the MAP + AS + ZnSO₄  blend.
