MicroEssentials® S15® Canola Fertility

Objective

Evaluate the yield response of canola to MicroEssentials® S15® (13-33-0-15S) compared to a MAP (11-52-0) + AS (21-0-0-24S) blend.

OVERVIEW

  • Proper applications of phosphorus (P) and sulfur (S) are critical for optimum canola yields.

  • A blend of MAP + AS (ammonium sulfate) is commonly used as a primary fertilizer source in canola-growing regions of North America.

  • MicroEssentials® S15® (13-33-0-15S) is a proprietary fertilizer that combines nitrogen (N), phosphorus (P) and sulfur (S) 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

Crop: Canola (Brassica napus)

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

Experimental Design: Small-plot RCBD with 4 replications.

Cropping Conditions:: Trials conformed to local cropping practices.

P Rate: 33 lbs P₂O₅/ac

S Rate: 15 lbs S/ac

Application Timing and Method: Fertilizer was applied with the seed at planting.

SUMMARY

  • In 2011, 2012 and 2013, MicroEssentials® S15® increased yield by 1.0 bu/ac, 1.6 bu/ac and 3.7 bu/ac, respectively.

  • The 3.7 bu/ac (6.1%) yield advantage of MicroEssentials® S15® in 2013 demonstrates its superior performance under excellent growing conditions.

  • The three-year average across 24 trials shows the statistically significant yield advantage of 2.6 bu/ac with MicroEssentials® S15® compared to MAP + AS. This data demonstrates the value of uniform nutrient distribution and season-long sulfur availability provided by MicroEssentials®.

Individual results may vary, and performance may vary from location to location and from year to year. This result may not be an indicator of results you may obtain as local growing, soil and weather conditions may vary. Growers should evaluate data from multiple locations and years whenever possible.
