  abstract = {{T}his study evaluated a framework for modelling the continuous exchange of carbon ({C}) between the atmosphere, plants, humus, and microorganisms, proposing a plant {C} model coupled to {MOMOS}, an existing microbial {C} model. {C} data were collected on low fertility cereal-legume cropping systems. {P}lant {C} and microbial {C} were modelled simultaneously and the growth parameters of plants and nitrogen-fixing microorganisms were fitted to the data. {A}ll {C} exchanges were successfully predicted using the same weather correction for plant and microbial processes. {M}ost of the photosynthetic production was allocated to the roots, reducing yields. {T}he {C} losses were found modelled mainly by root respiration for cereals, probably as an energy source for nutrient explorings, and by root mortality for legumes as a growth source for decomposers and symbiotic nodules. {T}he effect of root-nodule activity on shoot growth was found non-linear. {T}he system was modelled as a sink of 4.2 {M}g {C} ha(-1) year(-1) in the soil's labile {C} reserve. {T}his paper coordinates theoretical bases for modelling the processes regulating plant productivity associated with plant {C} losses. {T}he tool appears to be robust and is now available for calculating the essential parameters of agro-ecology and climate change.},
