Agroecology, Hydrogeochemistry, Media & Resources (UP2018.C101) (AGHYLE)

Research unit


The research unit AGHYLE (Agro-ecology, Hydrogeochemistry, Milieux & Ressources) is a unit of the Unilasalle Polytechnic Institute, certified by the HCERES. His research focuses on the study of the ecological interactions between plants, abiotic factors (of soils and climates) and edaphic organisms in order to understand their role in the functioning of the soil, nutrient dynamics and availability (N&P), pathogen cycles, and agroecosystem productivity.
The AGHYLE unit is supported by the development of three industrial research and training chairs: «biomes», «plant breeding» and «agromachinism and new technologies».
