4R Certification

4R Certification provides recognition for farmers who complete and apply 4R Nutrient Stewardship grower plans.

Sustainable farming is the future

By helping Canadian agri-retailers and crop advisors become 4R Certified, we can count acres under 4R Nutrient Stewardship to demonstrate how the Canadian agricultural industry is a leader in sustainable farming.

The 4R Certification Program is a voluntary program for Nutrient Service Providers, which include agricultural retailers, agricultural service provides, and certified professionals. The 4R Certification program translates 4R Nutrient Stewardship into a set of auditable criteria. To become 4R Certified, a Nutrient Service Provider must complete a third-party audit every two years to maintain certification. The Agri-Chemical Warehouse Standards Association (AWSA) is the third-party audit body conducting the 4R Certification Program audits in Canada.

The 4R Certification program evaluates retailers on sustainable 4R Nutrient Stewardship practices in the areas of training & education, nutrient recommendations & nutrient application, and documentation.

The 4R Certification program was first brought to Canada through the implementation of the program in Ontario in close collaboration with the Nutrient Stewardship Council, the Ohio Agri-Business Association and The Fertilizer Institute in the U.S. to ensure alignment between cross-border efforts.

In addition to Ohio and New York, the program is now available and implemented in the following Canadian province:
