Two-stage ditches reduce nitrogen pollution while draining farm fields


Sara McMillan at Purdue University and Jennifer Tank at University of Notre Dame are monitoring nitrogen and phosphorus loads coming from two-stage ditches in farmland waterways to document how effective restored floodplains are at holding nutrients in place. “By restoring mini-floodplains on each side of these formerly channelized ditches, you add the potential for enhanced biology and hydrology to cleanse the water through nutrient and sediment removal,” said Tank, whose primary work is in ecology and environmental biology.
