4R Nutrient Stewardship Certified Dealers



The fertilizer industry endorses a best management practice concept known as 4R nutrient stewardship. The 4R philosophy is an innovative and science-based approach that enhances environmental protection, expands production, increases farmer profitability and improves sustainability. The concept is to use the right fertilizer source, at the right rate, at the right time, with the right placement.

This voluntary new program provides a consistent, recognized standard for agricultural retailers in Indiana, Michigan and Ohio where surrounding waters drain into Lake Erie. As regulations are being considered, it’s critical retailers and their grower customers adopt best practices to realize long-term improvements.  You can find out more about the certification program here.

This group of dealers service/apply over 475,000 acres in the Western Lake Erie Basin(WLEB) and 477,000 acres outside of the WLEB.
