Poster discussion session on "Predicting soil N mineralization; relevance of extractable organic matter fractions" For background information on this topic see session details SSS4.2

Discussion meeting will contain:
a short 5-min presentation of the posters submitted
a discussion on the future of soil testing.

Subtopics in this discussion are:
1) define limitations of current soil testing approach (related to e.g. extraction procedure, measurement N mineralization, statistics, mechanistic understanding)
2) what are the future perspectives?
(e.g.,role of spectrophotometry, dynamic simulation modelling, use of covariates)
3) identify knowledge gaps
