Summary:SOMM, a simulation model of soil organic matter mineralisation, humification and nitrogen release, has been elaborated. The model takes into account the rate of the processes depending on litter fall's nitrogen and ash content, temperature and moisture. The functioning of the main groups of soil decomposers is reflected in the model. The model represents a system of linear differential equations with variable coefficients. The model has been verified on a basis of independent data of short-term laboratory and field experiments. The results of the simulation show the applicability of SOMM for a wide range of environmental conditions from tundra to tropical rain forest. The model can be used for modelling soil system and natural ecosystems' dynamics mostly.
