Yes, the 4R efficiency measures are important. They do a lot, but efficiency alone won't get us to where we need to go. The federal government very wisely put in a target of a 30% reduction in nitrogen-related emissions by 2030. Efficiency will get us part of the way, but really reducing absolute tonnage is going to be needed in order to meet that target. Tonnage is going the other way. I mentioned that in Saskatchewan we've quadrupled fertilizer use in just three decades. In Canada, it's doubled over about the same period of time. Those trend lines are going in the wrong direction.
We need 4R, but we need much, much more. Again, that's for things like these independent extension agrologists actually coming to the farm, standing in the field with the farmer and taking a whole-farm, whole-system lookânot just at how much fertilizer is going onto a field of canola, but at how that canola works within a larger cropping system of rotations, cover crops, soil health plans and all of that.
