农业土壤是一氧化二氮（N2 O）、一氧化氮（NO）和氨（NH3）的主要来源。关于在不同土壤含水量下施用有机肥的土壤中这些气体的排放量的资料很少。在新鲜桑迪壤土的大规模培养中测量N2 O、NO和NH3的排放，并与四种有机肥料（家禽垫料（PL）、堆肥植物残留物（CP）、污水污泥颗粒（SP）和牛农场粪肥（CM））、尿素肥料（UA）或零N对照（ZR）一起进行38天的修正。将肥料以40%、60%或80%的水填充孔隙（WFPS）添加到土壤中。结果表明，尿素和有机肥是N2 O和NO的重要来源，尿素的N2 O和NO排放量分别占施氮量的0.04 ~ 0.62%和0.23 ~ 1.55%。有机肥处理的N_2O和NO排放总量为0.01 ~ 1.65%，
Agricultural soil is a major source of nitrous oxide (N2O), nitric oxide (NO) and ammonia (NH3). Little information is available on emissions of these gases from soils amended with organic fertilizers at different soil water contents. N2O, NO and NH3 emissions were measured in large-scale incubations of a fresh sandy loam soil and amended with four organic fertilizers, [poultry litter (PL), composted plant residues (CP), sewage sludge pellets (SP) and cattle farm yard manure (CM)], urea fertilizer (UA) or a zero-N control (ZR) for 38 days. Fertilizers were added to soil at 40, 60 or 80% water-filled pore space (WFPS). The results showed that urea and organic fertilizer were important sources of N2O and NO. Total N2O and NO emissions from UA ranged from 0.04 to 0.62%, and 0.23 to 1.55% of applied N, respectively. Total N2O and NO emissions from organic fertilizer treatments ranged from 0.01 to 1.65%, and
