Nitrous oxide emissions from perennial grass cropping systems on a boreal mineral soil
Agriculture is the main anthropogenic source of nitrous oxide (N2O). Cultivation of perennial crops is a potential way to reduce N2O emissions. We quantified multi-year N2O emissions from two perennial cropping systems, reed canary grass (RCG) and a mixture of timothy and meadow fescue (TIM), on a b...
