If there were not already enough reasons why you should stop applying phosphorus-based fertilizers on your lawn, garden, or field here’s one more. You are helping harm the Great Lakes. It also harms smaller ponds and lakes, as well as wetlands, streams, and rivers.
The vast majority of lawns need no phosphorus – zero, nothing, nada. But too many property owners and lawn applicators keep piling it on. Fortunately, in Minnesota, Wisconsin, and Michigan, laws have been passed which ban the application of fertilizers containing phosphorus. Wondering why your neighborhood pond looks like the photo in this post – phosphorus in fertilizers.
Hopefully, all the other states in the Great Lakes watershed and the Province of Ontario will follow. This spring go green and save some greenbacks by allowing you lawn to be less green.
