Vegetative buffers reduce herbicide runoff

Posted November 29, 2012 at 11:55 am

Research has shown that vegetative buffers are very good at controlling sediment and keeping it out of waterways. But what about reducing herbicides?

“We have a major problem with that in the claypan soils in northeast Missouri,” said Bob Lerch, a soil scientist with the USDA Agricultural Research Service and an adjunct assistant professor at the University of Missouri.

Lerch and his ARS colleagues decided to see how well buffers reduced herbicides in soils with high runoff potential.

In 2004, the researchers began working with buffer plots at the MU College of Agriculture, Food and Natural Resources’ Bradford Research Center that had been used for studies focusing on sediment and nutrients. They conducted a preliminary study to see if buffer plots would work at all for herbicides.

“We got some
