Improving the mechanistic understanding of nutrient dynamics remains a challenge. Despite the wealth of biological knowledge, emphasizing that composition and activity of the soil food web regulate nutrient recycling; this biotic component is still not well incorporated in nutrient dynamic models. We investigate if the soil food web needs to be included in such models to understand organic matter dynamics. Two different modelling approaches exist which describe the control over organic matter dynamics. In donor controlled models, the decomposition process is driven by substrates quality. Whereas in top-down controlled models, the decomposition process is driven by soil food web activity. We derived a set of simple models depicting both approaches. We conclude that soil food web composition and activity should be explicitly represented in models to understand organic matter dynamics.
