Overview
• Corn needs sulfur (S) all season long. MicroEssentials includes two forms of S, providing both early and late-season S, along with nitrogen (N) and phosphorus (P) in each granule.
• MicroEssentials S10 uses technology that creates a unique chemistry around the fertilizer granule which results in increased nutrient uptake and increased crop yield compared to TSP.
• TSP contains 15% calcium (Ca), increasing the opportunity for P fixation, especially in calcareous soils.
Trial Details
Locations and Crop Management:
CROP: Corn (Zea mays L.)
YEARS: 2019-2024
DATA SOURCE: Replicated small-plot field studies conducted by university and/or independent third-party researchers yielding over the 2024 national yield average of 179 bu/ac
CROPPING CONDITIONS: All trials conformed to local cropping practices
N Rate: Balanced across treatments and applied according to local recommendations
P Rate: 60 or 80 lbs P2O5. /ac applied as MicroEssentials S10 or TSP. Treatment comparisons balanced for P
Application Timing: Preplant
Application Method: Broadcast
Results
Summary
• MicroEssentials S10 increased yield 6.2 bu/ac over TSP averaged across 23 site-years.
• Phosphate from MicroEssentials is more available than P from TSP, especially as soil pH increases.
• With N, P, and S, MicroEssentials provides complete crop nutrition in each granule. The result is uniform nutrient distribution and more effective delivery of essential crop nutrients than TSP or TSP blends can provide.
