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
A grassed buffer between a field and a stream provides important benefits to the environment but underground a tile pipe can send nitrogen straight to the stream. 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.

Transforming Drainage: Saturated Buffers
The Transforming Drainage project brings together research from experimental saturated buffer sites across the U.S. Midwest to evaluate the full potential of this new and exciting practice, and develop tools and resources that will help farmers, drainage contractors, conservation staff, and others locate, design, and install saturated buffers within tile-drained landscapes.
