Image Number D176-20 Soil scientist Norm Fausey collects bottom sediments from a constructed wetland. This wetland, located alongside a crop field, removes nitrate and sediment from field drainage water so they won't end up in streams. In dry years, water from the wetlands can be recycled back onto fields to boost yields.  Photo by Peggy Greb.  640 pixels wide: (d176-20.jpg)   Please visit our Image Gallery
