Carbon (C) and nitrogen (N) sequestration in plants and soil micro-organisms
is considered as a major phenomenon against global warming. The modeling of this phenomenon
aims at highlighting the role that the legumes-cereals mixed crop can play in the reduction of
greenhouse gases. It is based on field experiments in maize (Zea mays L.)-common bean
(Phaseolus vulgaris L.) intercropped system of the cereal agroecosystem in Setif region of
Algeria. For this purpose, the MOMOS model was selected and validated in a calcareous soil and
low phosphorus (P) conditions. It revealed some mechanisms that control the C and N
sequestration in the compartments of the complex soil-plant-atmosphere-microorganism system.
CN modeling results show that the daily growth of intercropped maize with common beans is
positively correlated with the microbial CN transformation during the cropping cycle, under
limited P and N conditions. Thus, this approach revealed the functional role of rhizobial
symbiosis in maintaining the balance between the different C and N exchanges from soil to
atmosphere and from atmosphere to soil.
