MicroEssentials® S10® — Potato Study

Objective

Evaluate the yield response of potato to MAP (11-52-0) and MicroEssentials® S10® (12-40-0-10S).

OVERVIEW

  • Phosphorus (P) management is a critical component of potato production systems and MAP is commonly used as a P source.

  • Additionally, sulfur (S) has been shown to increase tuber yield and quality.

  • MicroEssentials® S10® is a premium P fertilizer that provides uniform nutrient distribution, increased nutrient uptake, and two forms of S (sulfate + elemental) for season-long S availability.

Results

Potato Yield

SUMMARY

  • The addition of a premium phosphate source containing two forms of S can increase marketable potato yield.

  • Averaged across 10 site-years, MicroEssentials® S10® outperformed MAP by 27 cwt/ac.

  • These results demonstrate the benefit of higher yield from key features of uniform nutrient distribution, increased nutrient uptake and season-long supply of S (sulfate + elemental).

Individual results may vary, and performance may vary from location to location and from year to year. This result may not be an indicator of results you may obtain as local growing, soil and weather conditions may vary. Growers should evaluate data from multiple locations and years whenever possible.
