Aspire® High-Yield Management Corn


Evaluate the yield response of Aspire® with Boron (0-0-58-0.5B) against MOP (0-0-60) under highyield management systems.


  • High-yield management practices including stacked-trait hybrid technology, increased seeding rates, strobilurin fungicide applications and split applications of nitrogen have highlighted the need for balanced crop nutrition.

  • Micronutrients such as boron (B) are crucial for cell growth and reproductive development stages to increase yield.

  • Other research has shown that phosphorus (P) and potassium (K) fertilizers containing micronutrients in a single granule provide increased nutrient distribution and crop nutrient uptake compared to conventional fertilizer blends.

  • MicroEssentials® SZ® contains N, P, S and Zn fused into one nutritionally balanced granule, creating a single source for balanced crop nutrition.

  • Aspire® is the first-of-its-kind micronutrient-enhanced potash fertilizer. Manufactured using Nutriform® technology, Aspire® premium potash combines K and B in each granule to help achieve balanced crop nutrition.

Average Yield Advantage of Aspire over MOP Across 4 Years

  • Aspire® outyielded MOP by 9.5 bu/ac in 2011, 10.0 bu/ac in 2012, 9.4 bu/ac in 2013 and 4.5 bu/ac in 2014.

  • On average, corn yields increased by 8.8 bu/ac (4.3%) when Aspire® was compared to MOP.

  • Across 31 sites and 4 years, Aspire® demonstrated a 71% win rate over MOP.

  • Growing conditions varied greatly across the 4 years of study, but Aspire® showed a yield advantage in all years.

  • The results demonstrate the benefits of boron and uniform nutrient distribution in a high-yield management system.

Individual results may vary, and performance may vary from location to location and from year to year. This result may not be an indicator of results you may obtain as local growing, soil and weather conditions may vary. Growers should evaluate data from multiple locations and years whenever possible.
