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. 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.

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 understand and quantify the water quality benefits of 4R (right source, rate, time, and place) initiatives in the Western Lake Erie Basin (WLEB).

Since the mid 1990s, soluble P entering Lake Erie has shown an increasing trend, as have the frequency and severity of nuisance and harmful algal blooms. Evidence indicates that a considerable proportion of this soluble P comes from cropland. The 4R principles of nutrient stewardship have been promoted in the western Lake Erie basin (WLEB) and adoption is “catching on.
