Data was collected and analyzed from 15 farmers for the 2019-2021 crop years to demonstrate the impact of conservation on soil and water quality.

Underground trenches filled with woodchips, called bioreactors, are gaining traction as viable edge-of-field tools to remove nitrogen (N) from the water that drains from agricultural fields. A new study from Iowa State University looked at how woodchip degradation affected the performance and lifespan of these bioreactors.

University of Minnesota Extension explains the nitrogen cycle, how nitrogen can transform and end up leaving the soil through the atmosphere or local waterways.
