OVERVIEW
- 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® (12-40-0-10S-1Zn) is a proprietary fertilizer that combines nitrogen (N), phosphorus (P), sulfur (S) and zinc (Zn) fused into one nutritionally balanced granule.
- Growing conditions in North Dakota and the Canadian Prairie Provinces varied greatly across 2011, 2012 and 2013.
TRIAL DETAILS
Years: 2011-2013
Crop: Canola (Brassica napus)
Locations: 24 locations across the U.S. and Canada
United States – ND
Canada – AB, MB, SK
Data Source: Field studies conducted by third-party, independent researchers.
Experimental Design: Small-plot RCBD with 4 replications.
Cropping Conditions::
P Rate: 33 lbs P₂O₅/ac
S Rate: MAP + AS: 15 lbs S/ac
MicroEssentials® SZ®: 8.25 lbs S/ac
Zn Rate: 0.825 lb Zn/ac
Application Timing and Method: Fertilizer was applied with the seed at planting.
RESULTS
SUMMARY
- Across 2011, 2012 and 2013, MicroEssentials® SZ® increased yield over the MAP+AS blend by 0.6 bu/ac, 0.8 bu/ac and 2.4 bu/ac, respectively.
- The 2.4 bu/ac (5.1%) yield advantage with MicroEssentials® SZ® in 2013 demonstrates its superior performance under excellent growing conditions.
- The three-year average across 24 trials shows the statistically significant yield advantage of 1.5 bu/ac with MicroEssentials® SZ® compared to MAP + AS. This data demonstrates the value of uniform nutrient distribution and season-long sulfur availability provided by MicroEssentials®.
