Апстракт:
By solving the diffusion equation using the explicit finite difference method, the concentrations of the oxygen inside the soil are determined for various periods of time. Two different cases are investigated, with constant and daily changing air oxygen concentration. We have obtained that the influence of the periodical change of the air oxygen concentration on the oxygen concentration in the soil is more pronounced for smaller diffusion times at smaller lengths of the soil profile.
