The Main Influencing Factors to be Represented in a Mathematical Model of Soil Respiration

For mathematical modeling of soil respiration and soil carbon accumulation, it is necessary to set off the most significant factors governing soil forming and soil organic matter transformations. As few as possible factors should be set off and represented in a mathematical model to make the model liable to analysis. The object of this study is to set off a minimum of the most significant factors governing the processes of soil respiration, soil carbon accumulation and transformation. Two modelling approaches were considered: based on kinetic equations and based on steady-state equations. The validity of the hypothesis, that the main factors governing the features of soil as a carbon reservoir are temperature and precipitation, was tested.
