Performance Acre - Soybean Balanced Crop Nutrition


Evaluate soybean yield response to MAP (11-52-0) + MOP (0-0-60) and a combination of MicroEssentials® S10® (12-40-0-10S) + Aspire® (0-0-58-0.5B).


  • Phosphorus (P) and potassium (K), along with sulfur (S) and boron (B), are essential nutrients needed for a balanced crop nutrition program in soybeans. 

  • MicroEssentials S10 supplies multiple nutrients fused into one nutritionally balanced granule, promoting uniform nutrient distribution, increased nutrient uptake, two forms of S for season-long availability and higher yields.

  • Aspire combines potash along with two forms of B (fast and slow release) in every granule for uniform distribution, season-long B availability, and a flexible application window.

Performance Acre™ - Soybean Balanced Crop Nutrition - Results


  • Soybean yield increased with the addition of S and B.

  • MicroEssentials S10 + Aspire increased soybean yield 3.7 bu/ac over MAP + MOP.

  • Higher yields with the Performance Acre demonstrate the value of a variety of macro- and micronutrients, uniform nutrient distribution, increased nutrient uptake, and two forms of S (sulfate and elemental) and B (sodium and calcium borate) for a balanced crop nutrition program in soybeans.
