Saturated Buffers

A saturated buffer resembles a traditional buffer or filter strip, but it is designed to capture and treat water from underground tile drains. As water seeps slowly through the buffer, high organic matter in the soil promotes denitrification.

University of Illinois Saturated Buffer

Dr. Laura Christianson of the University of Illinois talks about how we can modify grassed buffers to remove nitrogen from the tile drainage water before sending the water downstream.
