 Using roots to tap into production potential
 | |  Learn more about the basics and benefits of soil health. | In many parts of the country, there are reservoirs of water and nutrients below cropland's "legacy plow-pan." But there's a problem. That dense layer of soil virtually locks out most cash crops, keeping their roots from reaching those vital resources. So how can farmers tap into that reservoir? At one time, plowing deeper was the answer. But plowing is only a temporary fix that requires bigger tractors, more fuel, and more time, which can make the plow-pan problem even worse. Here's a natural solution – use cover crops. Dr. Ray Weil, author of the 15th edition of The Nature and Property of Soils, explains how cover crops can help cash crops reach a treasure trove of production resources below the top few inches of soil. Watch the video (2:50), the second in a three-part series. It's science you can really dig! | | |
