A discussion paper examines Ottawa’s plan to reduce nitrous oxide emissions from nitrogen fertilizer use at the farm level by 30 per cent within eight years.

The target was announced in December 2020 and remains a priority for the federal government. The discussion paper indicates the required technologies already exist—it is a matter of how to increase their usage.

One of those practices is Fertilizer Canada’s 4R Nutrient Stewardship program—right source, right rate, right time, right place. Other common measures include soil testing and split nitrogen application. The discussion paper also mentions replacing synthetic fertilizer with manure, compost or digestate, as well as the use of enhanced efficiency fertilizers.

Farmers and farm groups are concerned about the possibility that new targets could result in policies restricting the volume of fertilizer used. The discussion paper mentions the government does not see this as the primary method for reducing the 30 per cent reduction target.

The discussion paper was posted on the Agriculture and Agri-Food Canada website on late Friday afternoon. Public comments can be made until June 3rd. Industry stakeholders have been told that a town-hall style meeting is planned for early April.
