Key Findings of the Canadian 4R Research Network

The purpose of this report is to present the findings of the Canadian 4R Research Network (also referred to as the ‘4R Research Network’). After a three-year independent research project engaging nine researchers across the country, the 4R Research Network has provided much needed scientific evidence to support the efficacy of the BMPs associated with 4R Nutrient Stewardship. As outlined in the subsequent pages, 4R Nutrient Stewardship enables Canadian growers from regions across the country to increase the profitability of their farms through higher yields or enhanced economic efficiencies while also improving their environmental sustainability by reducing greenhouse gas emissions, leaching of nutrients through the soil or harmful impacts on surrounding water resources.
