Aspire® Soybean High-Yield Management

Objective

Evaluate the yield response of Aspire® (0-0-58-0.5B) compared to MOP (0-0-60) in high-yield soybean management systems.

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.

Results

Soybean Yield

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.
