Aerating soil could become a key strategy for reducing agricultural emissions of atmosphere-damaging nitrogen oxides, according to a research team led by William R. Horwath of the University of California, Davis (Proc. Natl. Acad. Sci. USA, DOI: 10.1073/pnas.1219993110). Nitric oxide (NO) leads to health-harming ground-level ozone, and nitrous oxide (N2O) is a greenhouse . . .
