Article by Jill Sakai, UW-Madison News

Spring in Wisconsin heralds a new growing season. But the warming temperatures also bring heavier runoff from farm fields, carrying pollution and contaminants into the state’s lakes and streams.

Wisconsin’s waters have long been known to be negatively impacted by agricultural runoff, including phosphorus, nitrogen and sediments. To date, however, attempts to mitigate the resulting damage and improve water quality have been hampered by the problem’s complexity — Wisconsin has a lot of water and a lot of farm fields, and not all interactions between the two are equal.
