  abstract = {{W}e used the multi-agent {MIOR} simulator as an exploratory tool to discuss some basic modelling principles as regards soil organic matter ({SOM}) decomposition processes, which are viewed as the result of interactions between the soil living community (represented by {MM} micro-organisms entities) and the "dead" organic matter (the {SOM} resource represented by individualized {OM} entities). {I}n this paper we formalize the original offer-demand mechanism implemented in {MIOR} in a way that allows for the comparison of different conceptual points of view as regards the best way to couple biologically based population models (for the decomposer dynamics) and physically based first-order kinetic models (for the decomposed substrate). {W}e show that accounting for explicit interactions leads to the introduction of effective decomposition rates which vary in time as a function of the {M}/{C} living ({M}) versus dead ({C}) matter carbon content ratio. {M}ore generally, by means of numerical experiments, we show that, as soon as we account for temporal or spatial variations of the microbial biomass, it brings into question the classical way to estimate a constant {SOM} decomposition rate from soil carbon content decay data.},
