Abstract

The study proposes a model of transformation and decomposition of soil organic matter, based on using the rate of matter transformation as a continual scale of its transformation degree. The model is represented by one partial derivative differential equation that has an analytical solution. This model has only two adjustable parameters, while the number of experimentally determined parameters depends on how detailed the description of the plant litter is supposed to be. The model has been tested, and model parameters have been evaluated by comparing model predictions with the literature data on the stock of soil organic matter in different types of ecosystems.
