4R Advisory Committee LogoThe 4R Advisory Committee - Western Lake Erie Basin is seeking comments on the DRAFT 4R Nutrient Stewardship Certification Standard for Nutrient Service Providers. The 4R Advisory Committee welcomes comments on the draft as part of the process of creating a rigorous standard for Nutrient Service Providers working in the Western Lake Erie Basin.

This Draft Standard will be available for comment for a review period of 30 days, ending April 7, 2013.


The Standard is intended to encourage the adoption of 4R nutrient stewardship by specifying best practices for nutrient recommendations and nutrient application.  The Standard also includes an education component to ensure that new practices related to nutrient stewardship are adopted by Nutrient Service Providers and shared with their growers/customers.

The 4Rs of nutrient stewardship refer to using the Right Source of nutrients at the Right Rate and Right Time in the Right Place. 4R nutrient stewardship provides a science-based framework for plant nutrition management while also considering site-specific needs of a particular farm. The Standard applies to Nutrient Service Providers, including agricultural retailers, agricultural service provides, and certified professionals.  Grower customers (farmers) are NOT included under the scope of the Standard.

In creating a 4R Certification Program, the 4R Advisory Committee Western Lake Erie Basin has sought to provide guidance and direction for a consistent, recognized program for agricultural retailers, agricultural service providers, and certified professionals to help ensure that 4R nutrient sustainability goals are adopted and that in turn lead to long term positive impacts on water quality in the Western Lake Erie Basin.
