4R Designation

A professional credential for nutrient advisors delivering science-based 4R fertilizer recommendations.

What is 4R Designation?

The 4R Designation program trains professional agrologists (P. Ags) and Certified Crop Advisors (CCAs) in the principles of 4R Nutrient Stewardship. Designated specialists are qualified to develop 4R Nutrient Stewardship Plans and support farmers in implementing practices that improve nutrient efficiency, productivity, and environmental performance.

Acre Counting

Each year, Fertilizer Canada reports how many acres across Canada are under 4R Nutrient Stewardship. Acre counting recognizes growers for their commitment to sustainable nutrient management and provides the sector with credible data that supports advocacy, environmental reporting, and program development.
