Lake Erie Watershed Soil Phosphorus Study Shows Glyphosate Link

Mobilization and runoff of phosphorus to streams and lakes is associated with toxic algae blooms in Lake Erie and the Gulf of Mexico Dead Zone. For decades, soil scientists have understood phosphorus to form low-solubility compounds …
