Faculty, staff, and students from the Appalachian Laboratory, the Horn Point Laboratory, and Washington College and a local farmer were featured on a Maryland Public Television segment on Maryland Farm and Harvest, describing their on-farm research on the Delmarva Peninsula. Their research shows that the water level in drainage ditches can be managed to reduce nitrate leaching to the Chesapeake Bay, where it contributes to harmful algal blooms. However, they are also measuring emissions of the potent greenhouse gas, nitrous oxide, to make sure that the increased nitrate reduction that reduces water pollution isn't coming as a trade-off with increased greenhouse gas production. As shown in this video, preliminary results suggest only a small increase in the greenhouse gas emissions is being measured, while nitrate leaching is strongly curtailed.
With soils contributing almost one quarter of worldwide greenhouse gas emissions, researchers expanded the DAMM model to better understand microsite soil production and consumption of carbon dioxide, methane, and nitrous oxide.
