Work ExperienceI have been working on soil organic matter decomposition for about 10 years. I worked for 8 years in Martinique where I was involved in a EEC project (Soil fertility of Carribean small farming systems). We had field trials in farming systems located in 4 islands of the Lesser Antilles. I was in charge of field 15 N studies. Then I looked at the location of soil microorganisms. I spent 18 months at the CSIRO in Adelaide (South Australia) with Dr. J.N. Ladd where I looked at the effects of soil-substrat relationships on the location and the turnover of soil microorganisms. I have been in Dakar since September 1995. Since then I have been in charge of microbiological characterizations of soils under different land management (red fed crop such as millet, crop-fallow rotation and more recently agroforestry systems). Our field sites are located along a rainfall gradient ranging from 300 mm per year to 1200 mm per year. Our team comprises 2 nematologists, a plant physiologist and a
