When proper site conditions and design considerations are met, saturated buffers can be an effective method for reducing nitrate transport from subsurface drainage systems.

Scientists: Glyphosate Contributes to Phosphorus Runoff in Lake Erie

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.

By Laura Barrera posted on June 11, 2016 | Posted in Crop Protection, Nutrient Management

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.
