Nitrous oxide emission and methane oxidation potential in the pastoral soil under intensive dairy farm management

摘要：

Anthropogenic nitrous oxide ( N2 O) emissions from agricultural soils are estimated to contribute ～ 14％ of New Zealands greenhouse gas ( GHG) inventory ( New Zealand Climate Change Office 2007 ).The global annual soil sink for methane (CH4 ) was estimated to be 3‐9％ of the atmospheres removal rate (Smith et al.,2000).We report N2 O emission and CH4 oxidation rates in freely and poorly drained soils on an intensively managed dairy farm following a cattle urine application.
