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.
Locations and Crop Management:
CROP: Potato (Solanum tuberosum)
LOCATIONS: 6 trials (MB, MN, ND)
DATA SOURCE: Field studies conducted by independent third-party researchers.
EXPERIMENTAL DESIGN: Small-plot RCBD with 4 replications.
Cultivar: Russet Burbank
N Rate: Followed local recommendations
P Rate: 80 lbs P₂O₅/ac applied as MAP or MicroEssentials® SZ®
K Rate: 300 lbs K₂O/ac as MOP to the entire trial
Application Method: Preplant broadcast and incorporated
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.
