 Farming 101: What you need to know about tiling runoff

September 14th, 2015

For decades, farmers across Iowa have installed a network of drainage tubes known as tiles under the lush soil to create some of the world’s most productive farmland. But that same underground drainage system is also being blamed for environmental problems, including excess nitrates in Iowa’s waterways. Here’s a quick look at the problem and how tiling works.
