From the data gathered by the questionnaires, the main manure management practices and their prevalence can be reasonable established across some countries of the EU 27. The distribution and the analysis of the questionnaires allowed us to capitalize on 176 replies. This wasn't enough to fully represent management practices across all regions of the EU. Nevertheless, in support to inventories' projects, the analysis of the questionnaires provides information on management practices which will allow a support in the methodology to complete such inventories. Especially for certain criteria, we emphasize the importance of conducting surveys at the regional level. Consequently, the inventories that are derived from such questionnaires at regional or national levels would be more accurate. Such on-line questionnaire should be kept open in order to get a continuous improvement on data collection related to manure management.
