      abstract     = {The application of organic materials to agricultural lands
                      is considered good practice to improve soil organic matter
                      content and recycle nutrients for crop growth. The anaerobic
                      treatment of food waste may have environmental benefits,
                      particularly with regard to greenhouse gases (GHGs)
                      mitigation and enhancement of carbon sequestration.This work
                      presents the results from a field experiment to evaluate
                      CO(2) , CH(4) and N(2) O emissions from grassland amended
                      with digestate produced by anaerobic fermentation of food
                      waste. Experimental plots, located close to Rothamsted
                      Research-North Wyke, were established using a randomized
                      block design with three replicates and two treatments, added
                      digestate (DG) and the unamended control (CNT). The
                      digestate was applied on three occasions at an equivalent
                      rate of 80 kg N ha(-1) .The application of digestate led
                      to an increase in CO(2) emissions, especially after the
                      2(nd) application (74.1 kg CO(2) -C ha(-1)  day(-1) )
                      compared with the CNT soil (36.4 kg CO(2) -C ha(-1)
                       day(-1) ), whereas DG treatment did not affect the
                      overall CH(4) and N(2) O emissions. The total grass yield
                      harvested on a dry matter basis was greater in the DG
                      treated plots (0.565 kg m(-2) ) than in the CNT plots
                      (0.282 kg m(-2) ), as was the (15)  N content in the
                      harvest collected from the DG plots.The results suggest that
                      the digestate can be applied to agricultural land as a
                      fertilizer to grow crops. Our study was conducted in an
                      exceptionally dry growing season, so conclusions about the
                      effect of digestate on GHG emissions should take this into
                      account, and further field trials conducted under more
                      typical growing seasons are needed.},
