摘要：
Determining soil nitrification and denitrification rates comprising introducing a soil sample into a gas- and pressure-tight vessel to leave a gas space above the soil, hermetically sealing the vessel, and measuring the pressure, and oxygen (O2) and carbon dioxide (CO2) concentrations at least at the start and end of an incubation period of 0.5-24 hours, is new. An Independent claim is also included for apparatus for carrying out the novel method, comprising a sealable gas-tight vessel having at least one pressure sensor access port and at least one sealable inlet.
