74-7 Canola (Brassica napus) Fertilizer Seed Safety.
Poster Number 907
Trials were designed to evaluate the yield response of MicroEssentials S15 (13-33-0-15S) compared to mono-ammonium phosphate (11-52-0) + ammonium sulfate (21-0-0-24S) in canola at different P2O5 rates when applied with the seed. Final plant populations were evaluated (15-21 days after seeding) for seed injury caused by fertilizer.
MicroEssentials S15, a patented fertilizer (Fusion Technology by The Mosaic Company) with the analysis of 13-33-0-15S was compared to a blend of mono-ammonium phosphate (11-52-0) + ammonium sulfate (21-0-0-24S) at four rates of P2O5: 0 kg/Ha, 19 kg/Ha, 37 kg/Ha and 56 kg/Ha. Nutrients were balanced across both products and all treatments. This study was conducted in 2011 and 2012 on 10 locations across regions in the U.S. and Western Canada (North Dakota, Manitoba, Saskatchewan and Alberta).
The two year study found that MicroEssentials S15 out yielded all of the mono-ammonium phosphate + ammonium sulfate treatments. The range in yield improvement was 4% at the P2O5 rate of 19 kg/Ha up to 7.1% at the rate of 56 kg/Ha. MicroEssentials S15 showed significantly less injury to germinating seedlings compared to the traditional fertilizer sources, resulting in higher yields.
