The navigation in a deformable soil is related to the determination of traction and motion resistance via the soil strength. This strength is a function of parameters that are usually estimated using the bevameter tool. However, this tool is not usually available, hence the usage of another tool called cone penetrometer. In this study a new relationship was developed to estimate the bevameter parameters. This relation combines all bevameter parameters; (shear strength parameters and load penetration parameters), with a measurement called cone index. This equation is compared to another equation existing in the literature, that use only the load penetration parameters as a function of cone index, and then validated using experimental data obtained from Waterways Experiment Station (WES). The result shows that our equation is optimal compared to others existing in the literature. Finally, this equation is used to find all bevametric parameters of the soil inside the greenhouse strawberries.
