Our Focus Stewardship 4R’s Across Canada


4R Nutrient Stewardship has been promoted and applied across Canada through a number of provincial and regional programs and initiatives.

Ontario represents a portion of the Canada’s most viable and productive farmland. Ontario has been a leader in nutrient management planning for crop production. The province has embraced 4R Nutrient Stewardship (Right Source @ the Right Rate, Right Time, and Right Place®) as a valuable tool for meeting the province’s agricultural and environmental goals. 4R Nutrient Stewardship is a recognized part of the Ontario Government’s strategy to reduce nutrient runoff.

4R Nutrient Stewardship Certification


In 2015, a Memorandum of Cooperation (MOC) was signed between Fertilizer Canada, the Government of Ontario’s Ministry of Food Agriculture and Rural Affairs, and the Ontario Agri Business Association. This formalized a commitment to sustainable agriculture and environmental action in the province. The Ontario MOC mandates to implement, maintain and evaluate 4R Nutrient Stewardship programming to meet the needs of the government, farm groups, industry, and conservation groups. With a common commitment to improve the long-term quality of Lake Erie and the Great Lakes basin, the 4R Ontario Steering Committee is developing and implementing a 4R Nutrient Stewardship Certification program for Ontario agri-retailers.

4R Certification

This new, voluntary 4R Nutrient Stewardship Certification Program encourages agricultural retailers, service providers and other certified professionals to adopt proven best practices through the 4Rs, which refers to using the Right Source of nutrients at the Right Rate and Right Time in the Right Place.

In 2016, the 4R Ontario Certification Pilot Project was launched to evaluate the validity, suitability and accountability of the Ohio 4R Certification model for implementation in the Ontario marketplace. Pilot audits were conducted by the lead auditor from the 4R Ohio program. With feedback from the 4R Ontario Certification Pilot Project, the 4R Ontario Steering Committee developed and approved a list of requirements that form the proposed Ontario 4R Certification Standards.Visit our 4R Certification toolkit to find out more about becoming 4R Certified.


The Ontario 4R Certification program will be published by April 1, 2018 and implemented Fall 2018.

4R Nutrient Stewardship: Implementation in Ontario

4R Nutrient Stewardship offers agri-retailers in Ontario credibility and provides a strategic opportunity for farmers to help meet provincial objectives to improve the water quality of the Great Lakes and contributing watersheds while increasing agricultural productivity. Findings suggest significant benefits when compared to traditional practices. This will continue to ensure the effective protection and conservation Ontario’s agricultural soils, water quality, and ecosystem health as they relate to nutrients. Because every farm is different, the implementation of 4R Nutrient Stewardship practices are being adapted to Ontario’s agricultural production and unique conditions in order to maximize these results.

To date, more than 113,000 acres of farmland in Ontario can be attributed to 4R Nutrient Stewardship, with roughly 67 per cent of farms implementing some form of this nutrient planning and management method.  In 2016, there are four 4R Demonstration farms active in the province. To date, more than 20 4R Demonstration farms have been present in Ontario, validating the good nutrient stewardship and benefits to farmers and society. The 4R Demonstration Farm trials were originally developed in partnership with the Grain Farmers of Ontario to build a demonstration farm network in Ontario.
