Overview
- Phosphorus (P), potassium (K), and sulfur (S), along with zinc (Zn) and boron (B), are all essential nutrients needed for a balanced crop nutrition program in winter wheat.
- MicroEssentials SZ supplies nitrogen (N), P, two forms of S for season-long availability and Zn into one nutritionally balanced granule to promote uniform nutrient distribution and higher yields.
- Aspire is an innovative K fertilizer that uses Nutriform® technology to combine potash along with two forms of B (fast and slow-release) into every granule. This combination delivers B uniformly for uptake throughout the growing season and provides a flexible application window.
Trial Details
Crop Management:
CROP: Winter Wheat (Triticum aestivum)
YEARS: 2020-2021 LOCATIONS: 19 site years
DATA SOURCE: Replicated small-plot field trials conducted by university and/or independent third-party researchers.
CROPPING CONDITIONS: All trials conformed to local cropping practices.
N Rate: Applied according to local recommendations. P Rate: 40 lbs P2O5/ac applied as MicroEssentials SZ or MAP.
K Rate: Either 30 or 60 lbs K2O/acre applied equally as Aspire or MOP based on trial location and local practices.
Application Timing: Preplant
Application Method: Broadcast and incorporated
Results
Summary
• MicroEssentials SZ + Aspire increased yield 3.4 bu/ac over MAP+MOP across 19 trials in 2020 & 2021.
• Higher yields are achieved by using MicroEssentials SZ and Aspire together and demonstrate the value of uniform nutrient distribution, as well as the efficiency that two forms of sulfur and two forms of boron both have in providing season long nutrient availability.
