The DATAMAN database will be expanded to include additional data from countries not funded by the DATAMAN project and to include content for the additional soil parameters for soil C modelling and for nitrate leaching. Datasets will be collated from a) existing databases (e.g. ELFE), b) project participants, c) associated Global Research Alliance partners and d) peer-reviewed and relevant grey literature. This expanded database will continue to be aligned to the ERAGAS- funded project CEDERS, which is investigating the impact of animal feeding on GHG emissions. Data from empirical investigations of mitigation strategies for CH4, N2O and NH3 will also be collated.
