Nitrous Oxide Chamber Methodology Guidelines

The Nitrous Oxide Chamber Methodology Guidelines was identified as a priority project by the Livestock Research Group of the Global Research Alliance at its meeting in Amsterdam in 2011.

The New Zealand government requested proposals in December 2011 for the compilation of comprehensive guidelines for non-steady-state N2O chambers, to detail the current state of knowledge of N2O chamber methodologies and provide guidelines and recommendations for their use. In developing the guidelines, each chapter covers one of the key aspects – including design, deployment, air sample collection, storage and sample analysis, data analysis and data reporting –with additional chapters on automated systems and Health and Safety. The project was co-ordinated by AgResearch, a Crown Research Institute in New Zealand, who invited scientists from around the world to participate.

The guidelines aim to provide practitioners with information on best practice and factors that need to be considered in design and operation of N2O flux measurement programmes. Areas where there is no current consensus are described as ‘evolving issues’
