Introduction of root growth under mechanical stress analysis services In heterogeneous soils, the roots will experience a series of penetration resistances. The mechanical resistance has a direct and continuous effect on root growth, which in turn affects the development of the plant. There can be a complex and unique relationship between root elongation and penetration resistance. Therefore, we need to understand how the stress distribution around the roots varies between soil types and depends on the degree of radial thickening of the roots.

Much of the previous research has focused on obtaining detailed morphological and physiological information or the mechanics of soil compression around roots. Investigation of root growth under mechanical stress requires consideration of both the soil mechanics of root penetration and root growth physiology, which would bring new insights into the physiology of mechanically impeded roots. The rapid development of new technologies such as imaging, measurement and modeling techniques has contributed to the advancement of research in this area.
