MicroEssentials® SZ® Phosphorus Uptake in Corn (Greenhouse)

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

Phosphorus Uptake Rates by Source

SZCornPhosphorusUptake

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.
