Furthermore, an objective of this projects is also to maintain in Romania and Bulgaria the R&D potential in relation with the considered topic "Supply and operation of the tool 'modelling of farming impacts on the environment'". Indeed, the experience of the INRA and of the Agronomic Sciences Faculty of Gembloux in this field should ensure simultaneously the training or the perfecting of the Eastern and Central Europe countries' researchers and the development of recommendations and environmental-friendly agricultural practices, directly applicable by the farmer.
The European Community countries' ecological experience has emphasized the necessity of anticipating all environmental problems, notably regarding non-point source pollutions from agriculture in large-scale farming industry. The nitrates and pesticides fluxes linked to agricultural productions, and their impact on drinking water quality and on water ecosystem justify that actions be launched in such zones as the Bulgarian and Rumanian plains, which constitute the Danube's watershed, with the Black Sea as outlet.
Firstly, the study of "typical" situations, that is to say the most common crops and soils, will allow an estimation of the risk level in order to define the means to reduce nitrate and pesticides percolation downwards deep ground water and/or rivers.
The modelling of the Soil-Plant System will be used in this analysis. In that view, a first series of experiments will be performed to calibrate the model parameters. The in situ model validation will have two parts : i) a specific series of experiments and ii) a secondary validation will be performed with already available data.
From these models, both a risk evaluation and an identification of sensitive zones will be done in relation with the current agricultural practices. A frequential analysis based on long-term climatic records will be used. It aims at elaborating sustainable agricultural techniques suited to the site-specific characteristics.
