The first woodchip bioreactor installed in Iowa was recently recharged with new woodchips as part of the reconditioning process. The bioreactor, located near Jefferson, was installed nine years ago. Chris Hay, an environmental scientist with the Iowa Soybean Association, says the bioreactor has done its job in reducing nitrate flow into surface water.
Bioreactors are a key component of trying to meet the state’s nutrient reduction strategy, according to Hay.
There are currently about 40 bioreactors in Iowa.
