Scientists have developed a new edge-of-field water-treatment system that reduces the load of excess nutrients washing into waterways from farm drainage systems. Their method combines a woodchip bioreactor with a two-step biochar water-treatment module. A one-year field trial demonstrated that the system reduced both nitrogen and phosphorus runoff from farmland.
