Surprising Test Results
Studies at the University of Minnesota have found little difference in the level of phosphorus in storm runoff water when comparing areas using lawn fertilizers with phosphates versus areas where phosphates are not in use.
Fertilizer containing phosphate does its harm when homeowners fertilize too closely to the street, don’t close the hopper when turning their drop spreaders on the street, and keep it open over any paved area. It’s a part of the problem, you bet. Applied correctly, however, lawn fertilizer is not the culprit many think it is.
If you are interested or curious about eutrophication, however, I encourage you to go this column for more information. Parts of it are pretty decent slogging.
