BIOmE aims at understanding abiotic and biotic processes supporting a number of soil ecosystemic functions in the agro-ecosystems. Knowledge acquired from these basic researches is used to (i) assess and monitor the impact of different agro-ecosystems management strategies on soil ecosystemic functions and (ii) propose and develop strategies reducing the dependency of crop production to agrochemicals and enhancing biological processes supporting ecosystemic functions that soil naturally provides.

The research of BIOmE aims at:

- Understanding of the role of soil biodiversity and biotic interactions in supporting ecosystemic functions,

- Evaluating and monitoring the impact of agro-ecosystems management strategies on soil ecosystemic functions,

- Developing ecological engineering approaches promoting soil ecosystemic functions and bioindicators assessing the performance of soil ecosystemic functions.

BIOmE is studying soil regulating functions contributing to gas and nutrient regulations (i.e. C and N cycles with a focus on greenhouse gas emission), pest control (i.e. barrier effect to pathogen dispersal), water purification (i.e. agrochemicals (i.e. fertilizers and pesticides) dissipation) and soil provisioning function contributing to plant watering (i.e. water supply). BIOmE is carrying out studies at different level of biological organization (model organism, population, community), at different scales (microcosm, mesocosms, field, landscape, territory) by applying a multidisciplinary approach combining expertise in agronomy, soil science and microbial ecology. BIOmE is developing scientific collaboration with IPM and GESTAD on soil regulating function supporting biological control of pests in the crops (i.e. fungal diseases and weeds, respectively).
