Long term study shows grasslands can recover naturally from too much atmospheric nitrogen

(Phys.org)—A long term study conducted by managers of The Park Grass experiment at Rothamsted Research in Harpenden, UK, shows, according to a team of researchers from Germany and the U.K., that under certain conditions, grasslands are able to recover naturally from overexposure to atmospheric nitrogen. In their paper published in the journal Nature, the team describes the condition of grasses and soil at the research center over the course of the past century and a half and what has been learned from it. David Tilman and Forest Isbell with the University of Minnesota offer a News & Views piece on the work done by the team and compare it with findings in other parts of the world.
