OVERVIEW
- Winter canola is typically grown in the south-central region of the United States.
- Proper applications of phosphorus (P) and sulfur (S) are critical for optimum canola yields.
- Blends of MAP + AS (ammonium sulfate) are commonly used as a primary fertilizer source in canola-growing regions of North America.
- MicroEssentials® SZ® is a premium P fertilizer that contains nitrogen (N), P, S and zinc (Zn) fused into one nutritionally balanced granule, leading to uniform nutrient distribution.
- MicroEssentials® SZ® contains two forms of S. Sulfate S (SO₄²⁻) is available early in the season while elemental S provides season-long availability.
TRIAL DETAILS
Locations and Crop Management:
Crop: Canola (Brassica rapa cv. ‘Canola’)
Year: 2015–2016
Data Source: Field studies conducted by third-party, independent and university researchers.
Experimental Design: Small-plot RCBD with 4 replications.
Cropping Conditions:
P Rate: 33 lbs P₂O₅/ac
K Rate: As recommended by the soil test.

RESULTS
LOCATIONS: 6 trials across the United States – KS, OK, TX
SUMMARY
- MicroEssentials® SZ® showed a 5.4 bu/ac (13.3%) yield advantage over MAP.
- MicroEssentials® SZ® increased yield by 4.1 bu/ac (9.8%) over MAP + AS + ZnSO₄.
- This research demonstrates the benefits of balanced crop nutrition and a season-long supply of S from MicroEssentials® SZ®.
