Area producers gathered at Lanehaven Farms near Waterloo on September 18 to get their first look at a couple of conservation practices that are still relatively new in the state of Iowa- the denitrification bioreactor and saturated buffer. In an event hosted by the Black Hawk County Conservation Soil and Water District, the Iowa Soybean Association and Hollis Farms, farmers learned two ways they can significantly reduce the number of nitrates running off their farm fields into neighboring creeks, streams and rivers. Such a reduction will help improve the overall water quality in the state and help reduce the chemicals that ultimately wind up in the Gulf of Mexico, where they feed massive algae blooms that result in large areas where no aquatic life can survive.
