Résumé : Plant roots are the most important part for taking up nutrients and water to the main stems. Roots grow in the path of minor resistance and they extend in the porous spaces of soil. The roots change their directions when they find Peds that are aggregates of resistant soil. Besides, following the path of minor resistance, roots also grow where the media is better. The roots can avoid the dry and arid soil while they grow in the moist and fertile soil. In this paper, we are interested in how the roots grow in the soil volume based on nutrient concentration. The roots seek the maximum nutrient concentration and find the best direction and elongate to that direction. During the roots penetrate to the soil volume, the nutrient is changing by diffusion process. The roots can also uptake the nutrient to root stems when the roots reach the soil voxel (volume element). At each time step, the uptake nutrient by root can be calculated. The visualization of root growth is presented in the paper.
