OVERVIEW
- High-yield management practices for soybean (crop protection, full-season variety, increased seeding rate, etc.) have heightened the need for balanced crop nutrition.
- MOP is commonly used as a potassium (K) source in soybean production.
- Micronutrients such as boron (B) are essential for plant growth and often overlooked in the effort to achieve balanced crop nutrition.
- Granular B products can be blended with K, but application of these blends leads to undesirable distribution.
- Aspire® is the first-of-its-kind micronutrient-enhanced potash fertilizer. Formed using Nutriform® technology, Aspire® combines K and B in each granule to help achieve uniform nutrient distribution.
TRIAL DETAILS
Locations and Crop Management:
Crop: Soybean (Glycine max)
Years: 2015–2016
Data Source: Field studies conducted by third-party, independent researchers.
Locations: 12 trials across the U.S. and Canada United States – IL, KY, MI, OH, WI Canada – ON
Experimental Design: Small-plot RCBD with 4 replications.
Cropping Conditions:
P Rate: 50 lbs P₂O₅/ac
K Rate: 120 lbs K₂O/ac
B Rate: 1 lb B/ac
Application Timing and Method:Preplant broadcast incorporated
Results
SUMMARY
- The application of K and K + B both resulted in increased soybean yield.
- MOP outyielded the check by 1.5 bu/ac (2.3%).
- Aspire® outyielded MOP by 2.7 bu/ac (4.0%).
- These results demonstrate the benefits of Aspire® to maximize soybean yield.
