Upgraded versions of decision support systems for a better estimation of grassland DM production and better decisions by farmers

Several decision support systems are available in Europe regarding grassland management and most use the DM production as a key element. Various prediction models are available for DM production, with different precisions, especially because of the range of soil and climate conditions that can be met across Europe.A synthesis will be made of existing tools, with a precise description of strengths and weaknesses and their domain of optimal utilization. They will also be made easily accessible through the right links. We will not upgrade them as for most of them they were not developed by members of our consortium.
