Glossary of terms on livestock manure management

"Manure management, utilisation and the potential impacts on the environment are topics of high relevance across Europe. It is well recognised that internationally coordinated research and development and exchange of experience can greatly benefit science, technology transfer and the development of the corresponding policy framework across Europe. A major handicap in international collaboration, and a major source of misunderstandings, in these areas is the lack of a standardised terminology.
