MicroEssentials® S10® Phosphorus Uptake (Greenhouse Trial)

Objective

Quantify the increase of phosphorus (P) uptake with MicroEssentials® S10® (12-40-0-10S) applied to corn compared to DAP (18-46-0) and DAP-based blends that supply the same rate of nitrogen (N), P and sulfur (S).

OVERVIEW

  • Balanced crop nutrition is critical for corn production.

  • MicroEssentials® S10® supplies N, P and S in one nutritionally balanced granule.

  • Two forms of S, sulfate sulfur (immediately available) and elemental sulfur (slowly available), provide season-long S availability.

  • 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

Locations and Crop Management:

Crop: Corn (Zea mays)

Year: 2013

Locations: SabancI University, Turkey

Data Source: Dr. Ismail Cakmak

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

Treatments: DAP (18-46-0), DAP + ammonium sulfate (21-0-0-24S), MicroEssentials® S10® (12-40-0-10S)

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

Results

Phosphorus Uptake by P Fertilizer Source

SUMMARY

  • MicroEssentials® S10® increased P uptake by 23% compared to the DAP and 14% compared to DAP + AS.

  • MicroEssentials® S10® increased P uptake through increases in both plant dry matter (biomass) and P concentration (%).

  • MicroEssentials® with Fusion® technology combines N, P and S into one nutritionally balanced granule and promotes improved P uptake.
