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.

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.
