Evaluating the 4R Nutrient Stewardship Concept and Certification Program in the Western Lake Erie Basin
IPNI-2014-USA-4RN09
Since the mid-1990s, the frequency and extent of algal blooms and loadings of dissolved phosphorus (P) in the Western Lake Erie Basin (WLEB) have been on increasing trends. Agricultural crop management has been identified as a primary source of P to the Lake. Over the past 2-3 years, educational programs directed at growers and nutrient service providers (e. g.

Interpretive Summary
The increase in harmful algal blooms in Lake Erie since the mid-1990s is correlated with an increasing trend in dissolved phosphate loading. This multi-disciplinary research project, initiated in July 2014 with an end date of June 2019, aims to quantify the water quality benefits of 4R initiatives in the Western Lake Erie Basin (WLEB). As of January 2018, 37 retail locations reaching almost two million acres, had achieved certification in 4R Nutrient Stewardship.
The increase in harmful algal blooms in Lake Erie since the mid 1990s is correlated with an increasing trend in dissolved phosphate loading. A considerable proportion of this dissolved phosphate comes from cropland. This multi-disciplinary research project, initiated in July 2014, aims to quantify the water quality benefits of 4R initiatives in the Western Lake Erie Basin.
