Clean Lakes Alliance, USGS, and Madison city researchers have determined leaves from yard waste piled up on the street are causing phosphorus loading in the Yahara watershed and beyond. Leaves release phosphorus as they break down, and by doing so, are labeled one of the largest sources of urban phosphorus pollution. A community member can decrease phosphorus pollution by 40% from just keeping the piles of leaves on their lawn (or in yard waste bags) while waiting for waste removal. The phosphorus will naturally fertilize the lawn, and filter the nutrients after rainfall as well. Read the full article with video here.
