Abstract

New model of belowground competition is proposed. The model is operating on simulation grid and can simulate growth of root systems in mixed stands taking into account the irregularity in horizontal and vertical distribution of roots’ biomass. The main outputs are the density of roots in each cell and amount of nutrients captured by each tree.
