Abstract
Nitrous oxide N2O emissions and denitrification losses from an irrigated sandy loam soil amended with composted municipal solid waste MSW sheep manure SM surface applied pig slurry SPS incorporated pig slurry IPS or urea U were studied under Mediterranean conditions We quantified emissions in both the presence and absence of maize and N2O production via denitrification and nitrification pathways using varying concentrations of acetylene Discounting the N2O lost in the Control the percentages of N2O lost in relation to the total N applied were greater for urea 180 than for MSW 050 SM 046 SPS 102 or IPS 127 In general plots treated with organic fertilisers emitted higher amounts of N2O when under maize than bare soil plots On the other hand greater denitrification losses were also recorded for plots in the absence of plants between 97 and 293 kg N2ON ha−1 than for areas with plants between 71 and 241 kg N2ON ha−1 The proportion of N2O produced via denitrification was greater from fertiliser treatments than for the controls and also greater without plants between 66 and 91 of the N2O emitted than with plants between 48 and 81The authors are grateful to the Spanish Commission of Science and Technology Project AGL2000 1554−C02 for financing this research It is also a pleasure to acknowledge Ana Muelas Demetrio González and Asunción de Diego for their technical assistance We would like to thank Mark Theobald and Phil Nightingale for his useful comments
