  abstract = {{T}he modeling of carbon ({C}) and nitrogen ({N}) fluxes between microorganisms and plants in pure and associated cultures of durum wheat and faba bean demonstrated a close link between the {C} and {N} cycles in agroecosystems. {T}he {MOMOS} (microorganisms and organic matter of soils) model integrates simplified descriptions of photosynthesis (origin of organic {C} in soil), {N} microbial exchange (soil origin for {N}), {N} fixation (atmospheric origin for {N}), and plant growth with an organic matter decomposition core that has the soil microbial community at its center. {T}his work provides estimates of the exchange parameters between plant organs and microbes, which were compared to literature data when available. {I}n a connection with photosynthesized {C}, the root demand for inorganic {N} can be adjusted by its microbial production. {O}ur approach is a new methodology for improving plant production, by optimizing the interactions with soil microorganisms. {A}dditionally, the coupling of plant growth and microbial processes enabled determining changes of the organic compartments of soil. {I}n the unfertilized limestone soil of this study, sequestration was found to be located in the labile microbial metabolites for one year, then significantly transferred to stable humus during 6-year intercropping. {T}hus, we propose the {MOMOS} mathematical tool, not only for guiding ecological intensification, but also related to the management of agroecosystems for climate change mitigation.},
