Suitable Fertilizer Sources For Canola
As a sensitive crop, canola requires careful management to grow to its full potential, including selecting the right fertilizer source, rate, time, and placement. The following research compiled by the Canadian Canola Council examines various studies on suitable fertilizer choices and 4R nutrient management for canola.
Benefits polymer-coated urea can have over standard urea
- A multi-year Canadian study by Robert Blackshaw comparing the impacts of polymer-coated urea (ESN) with standard urea on canola.
Improved nitrogen-use efficiency and reduced nitrous oxide emissions using nitrogen inhibitors
- A 2019 study by Richard Farrell analyzing the factors that contribute to nitrous oxide emissions from canola residues and canola meal.
The impact of source and placement of nitrogen and sulfur fertilizer sources
- A 2017 study by Ramona Mohr investigating the right source and right placement of various nitrogen and sulfur fertilizer sources on canola.
Yield response to sulfur fertilizer sources
- A Canadian study led by Cynthia Grant evaluating practices to improve sulfur nutrient management in canola.
Evaluation of enhanced efficiency phosphorus fertilizers
- A 2008-2010 study led by Cynthia Grant comparing traditional and enhanced efficiency phosphorus fertilizer sources on canola emergence, yield, maturity, and quality.
