They are interested in the decomposition process of manure, either put directly on the grassland from the cattle, or sprayed on it after storage in a silo. They are also interested in the breakdown of N from fertilizer. In fact the role of N in manure is the main interest. Has anybody ever modelled this process and who has any suggestions ? _______________________________________________________________________ Onno M.
