Manitoba Co-operator: Precision 4R cuts farm greenhouse gas emissions

Precision crop maps can help canola producers apply 4R nutrient management if their fields have a lot of up and down, a researcher with the University of Manitoba says.

There’s been growing interest in precision 4R fertilization over the past few years, said Mario Tenuta during the Canola AgriScience Cluster Research Roundup webinar in June.

The 4R movement has been key framework for Fertilizer Canada, gotten official support from Manitoba Agriculture and has been touted and incentivized by various provincial and federal commodity groups, funding programs and organizations like Farm Credit Canada.

But Western Canada and even individual farms have a lot of variation in their soils and topography, Tenuta noted, and that’s a challenge for farmers looking to adopt 4R.
