摘要: The availability and spatial distribution of oxygen (O2) in agricultural soil are controlling factors in the production and emission of nitrous oxide (N2O) to the atmosphere, but most experiments investigating the effects of various factors on N2O emissions in soil have been conducted without determining the content and distribution of O2. This complicates data interpretation and leads to speculative conclusions about which nitrogen transformation processes are responsible for N2O production. Using an O2–specific planar optode, this …
