What is Nitrous oxide emissions in soils cropped with maize under long-term tillage and under permanent pasture in New Zealand about?
Information on the in ̄uence of tillage on nitrous oxide (N 2 O) emissions is needed by researchers, policy makers and farmers for assessment of global rami®cations of warming potential of greenhouse gas N 2 O. This research evaluates the effects of continuous long-term tillage and seasonal changes in N 2 O emissions in New Zealand temperate climate. The experiment was conducted in a Kairanga silty clay loam (Eutric Gleysol) where maize (Zea mays L.) was grown continuously for either 17 (K17) or 34 (K34) years, with conventional tillage. An adjacent permanent ryegrass (Lolium perenne L.) and clover (Trifolium sp.) pasture (PP) was used as a control. Mean N 2 O emissions under K17 and K34 and PP ranged from 0.04 to 1.35, 0.03 to 1.13, and 0.03 to 0.99 g N 2 O-N/ha/h, respectively. Average annual N 2 O emissions from K34 were slightly lower than those in the K17 ®elds although there were no differences in N 2 O emissions between PP and K17. Depleted organic C, total N and microbial biomass C in K34 as compared with K17, possibly limited denitri®cation process and decreased N 2 O emissions. Soil water content (SWC) was a key factor controlling N 2 O emissions in both pasture and cropp
