Biogeochemistry of pollutant transfers in cultivated environments

The module content is divided into six sequences:

1) Introduction by the EU: scientific and operational challenges of biogeochemical and water quality issues in agricultural watersheds;

2) Physicochemical and hydrological processes determining the availability and mobility of pesticides in a watershed;

3) Tutorial: guided modeling work on the transfer of plant protection products;

4) Biogeochemical cycle of phosphorus in agricultural systems;

5) Nitrogen cycle and balance in agricultural watersheds;

6) TD: Assessment of nitrogen balance in a watershed, diagnosis of surface water contamination

The objective of this module is to present the biogeochemical functioning of watersheds, focusing on the analysis and modeling of processes that determine the chemical quality of surface water, soil water, and groundwater in relation to agricultural activities. To this end, emphasis is placed on three chemical compounds with significant environmental and health implications: plant protection products, and compounds in the nitrogen and phosphorus cycles.
