Low soil pH and certain metals are causing glyphosate to release phosphorus from the soil, which is responsible for about 25% of dissolved reactive phosphorus runoff in the Maumee watershed.
Scientists now know that the increase in dissolved reactive phosphorus (DRP) runoff that’s been plaguing the western Lake Erie basin is mostly coming from farms located in the Maumee watershed.
