Potato

MicroEssentials® SZ® Potato Study

Objective

Evaluate potato yield response to MicroEssentials® SZ® (12-40-0-10S-1Zn) compared to MAP (11-52-0).

Overview

  • Nitrogen (N), phosphorus (P), sulfur (S), and zinc (Zn) are key components of a potato nutrition program.

  • Season-long S availability is critical for improved chlorophyll production, carbohydrate synthesis, and ultimately yield.

  • Zinc is necessary in various enzymatic reactions and therefore influences tuber starch and protein levels.

  • MicroEssentials® SZ® contains four nutrients (N, P, S, and Zn) combined into one granule, providing uniform nutrient distribution, increased nutrient uptake, and season-long S availability.

Potato Study Locations and Results

Summary

  • Potatoes responded to the addition of S and Zn.

  • MicroEssentials® SZ® increased marketable yield over MAP by 30 cwt/ac.

  • These results demonstrate the benefit of higher yield from key features of uniform nutrient distribution, increased nutrient uptake, and season-long S availability.
