MicroEssentials® SZ® (In-furrow) in Winter Wheat

Objective

Evaluate the yield response of winter wheat to applications of MAP (11-52-0) and MicroEssentials® SZ® (12-40-0-10S-1Zn) when placed in-furrow with the seed (Air-drill placement).

OVERVIEW

  • MAP (11-52-0) is commonly used as a phosphorus (P) source and applied with the seed in winter wheat cropping systems.

  • In addition to nitrogen (N) and P, other nutrients like sulfur (S) and zinc (Zn) are beneficial to achieve maximum yield.

  • MicroEssentials® SZ® (12-40-0-10S-1Zn) is a dry granular fertilizer that provides uniform nutrient distribution, increased nutrient uptake, and two forms of S (sulfate + elemental) for season-long availability.

TRIAL DETAILS

Crop: Wheat (Triticum Aestivum)

Years: 2017-2019

Data Source: Field studies conducted at university sites by Kansas State University.

Locations: 9 trials across 8 locations in Kansas.

ME1129 AgriFact-Map

Experimental Design: Small-plot RCBD with 4 replications.

Treatments: MAP (11-52-0) MicroEssentials® SZ® (12-40-0-10S-1Zn)

N Rate: Followed local recommendations and was balanced across all treatments.

P Rate: 40 lbs P₂O₅/ac as MAP or MicroEssentials® SZ®.

S Rate: 10 lbs S/ac from MicroEssentials® SZ®.

Zn Rate: 1 lb Zn/ac from MicroEssentials® SZ®.

Application Details: Cropping systems followed local practices. Fertilizer was placed in-furrow with the seed to simulate large-scale air-drill applications.

Results

Winter Wheat Yield Response

SUMMARY

  • Winter wheat yields increased with the addition of sulfur and zinc.

  • Averaged across 9 site-years, MicroEssentials® SZ® applied at 100 lbs product/ac outperformed MAP by +4.1 bu/ac.

  • MicroEssentials® SZ® applied with the seed at planting provides superior performance to the traditional practice of only applying MAP.
