Current research interests & achievements

Research interests: My research focuses on the soil-plant transfer of phosphorus in agro-ecosystems. My objectives are a better understanding and modelling of processes that govern soil P availability, root P acquisition and crop growth response. Accordingly, I will develop new tools to improve P use efficiency by crops and to limit P losses to environment.

Tools: for this I develop numerical models that describe soil P availability, root P uptake and crop P response. These models are based on experiments in field and controlled condition to test some hypothesis on effects of P limitation. One of my main expertise is on the use of radioisotope (32P) to trace the P transfer from soil to the plant and within plant compartments. The other one is the numerical modelling of soil-plant transfer.


Phosphorus, plant nutrition, biogeochemistry, plant P response, modelling, phosphorus fertilization, environment, P recycling, P use efficiency.
