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
DAP + AS + ZnSO₄ blend was balanced for phosphorus, sulfur, and zinc rates
TREATMENTS:
No phosphorus (UTC)
DAP
DAP + AS + ZnSO₄
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
SUMMARY
Corn phosphorus uptake was greater with MicroEssentials SZ than any other treatment.
MicroEssentials SZ treated plants showed an increase in plant dry matter (biomass) when compared to DAP or a DAP + AS + ZnSO₄ blend.
MicroEssentials SZ treated plants had 39% greater phosphorus uptake at V6 growth stage than plants treated with DAP or a DAP + AS + ZnSO₄ blend.
