Abstract
The EC land information system has been combined with meteorological, topographical and crop parameter data, and with historical agricultural statistics, to produce an integrated database suitable as input to a European-level crop growth modelling system. The selection of variables to be included in the database was based on both data consistency and availability throughout the continent, and on the relevance to the distribution of crop growth on that scale. The data in the integrated database are pre-processed to assign values to grid squares of 50 km x 50 km, which form the basic modelling units of the MARS crop growth model, although the simulation process also takes into account the variability of soils within the grids.
