Last year I invited Dr. Tom Isenhart to speak at a field day about saturated buffers. He shared with us how they work (they re-route drainage tile water along buffers) and their effectiveness (on average they filter out about 50% of the nitrate), but then he surprised me by talking about the benefits of good old-fashioned buffers. This was noteworthy because Dr. Isenhart literally invented saturated buffers! He collaborated with a colleague at the USDA Agriculture Research Service, Dr. Dan Jaynes, to pencil out the idea (rumor has it, on a cocktail napkin) over ten years ago. But here he was at a field day espousing the benefits of the old-school – some might say vintage – buffers of yore.
