Performance Acre™ – Corn Balanced Crop Nutrition – AgriFacts

OVERVIEW

• Phosphorus (P) and potassium (K), along with sulfur (S), magnesium (Mg), and boron (B), are essential nutrients needed for a balanced crop nutrition program in corn.
• 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.
• K-Mag is a unique 3-in-1 nutrient source that features low chloride, water soluble nutrients, and does not affect soil pH; regardless of application rate.

TRIAL DETAILS

Crop: Corn (Zea mays)

Years: 2020-2021

Locations: 11 trials across the following states – IA, KS, MN, ND, NE, SD

Data Source: Field studies conducted by third-party, independent researchers.

Experimental Design: Small-plot RCBD with 4 replications.

Cropping Conditions: All trials conformed to local cropping practices.

TREATMENTS:

Treatment (Trmnt) / Rates / Timing:

1. N Rate: Applied according to local recommendations
2. P Rate: 80 lbs P2O5/ac applied across all treatments as MAP (11-52-0) or DAP (18-46-0)
3. K Rate:
   • 2020: 60 lbs K2O/ac as Aspire or Aspire (50) + K-Mag (10)
   • 2021: 50 lbs K2O/ac as Aspire or Aspire (40) + K-Mag (10)
4. Application Timing: Preplant

Application Method: Broadcast Incorporated

RESULTS

SUMMARY

• Addition of Aspire increased corn yield 8.1 bu/ac compared to the control (N+P).
• Replacing a small amount of Aspire with K-Mag increased corn yield by 4.2 bu/ac over Aspire averaged across 11 trials (2020-2021).
• Higher yields with the Performance Acre demonstrate the value of uniformly distributed macro- and micronutrients for a balanced crop nutrition program in corn.
