The following is part of a series featuring the results of student research on water quality in the Red Cedar Watershed:

For my research done over summer 2017, we analyzed the Minnesota Phosphorus-Free Lawn Fertilizer Law’s effects on surface water quality. Essentially, we set out to determine if Minnesota’s statewide law had produced its intended effect of reducing phosphorus content in surface waters like lakes, rivers, streams.

We wanted to find out whether a policy of the Minnesota law’s caliber should be implemented in the state of Wisconsin. The Wisconsin state legislature enacted a similar statewide policy in 2010. But the Wisconsin law pales in comparison to the stringency of the Minnesota law. For example, it is still possible to purchase phosphorus fertilizer in Wisconsin, the sale of which has been completely eliminated in Minnesota.
