Researchers from the University of Manitoba presented ‘4R’ research at a self-guided field tour near Carman in late July.

4Rs reduce greenhouse gas emissions

Agriculture is the major emitter of nitrous oxide, researchers say

The 4Rs of nutrient stewardship can decrease emissions of the greenhouse gas nitrous oxide (N2O) anywhere from 20 to 40 per cent, according to research out of the University of Manitoba. “The vast majority of the nitrous oxide that is emitted is from agriculture,” said Mario Tenuta, professor of soil ecology at the University of

Adding more nitrogen in crop, instead of in the fall or spring before planting, is one way to use nitrogen more efficiently. The 4R tour visited Tyler Russell’s cornfield near Carman where about 60 pounds of nitrogen was applied at the V4 stage. Depending on the crop, more will be applied just before tasselling.

What is 4R Nutrient Stewardship?

Manitoba is not like other agriculture areas looking to implement 4R, the room heard during the latest 4R Nutrient Stewardship training workshop in Brandon Feb. 23. The four Rs (right nutrient source applied at the right rate at the right time in the right place) form the backbone of Fertilizer Canada’s campaign to balance environmental

4R Nutrient Stewardship taking more to the web

The 4R Nutrient Stewardship initiative has expanded training modules, 
accreditation and data logging online

Manitoba’s 4R Nutrient Stewardship is heading online. The program, announced in 2013, is a shared undertaking by the Canadian Fertilizer Institute, Manitoba government and the Keystone Agricultural Producers. It aims to balance environmental and agricultural interests. Four years later, the initiative has expanded to encompass education and tracking online. Initially packaged exclusively through day-long accreditation workshops,
