Soil strength

Definition (http://www.usyd.edu.au/agric/ACSS/sphysic/strength.html)

Stated qualitatively, soil strength is the capacity of a soil to withstand forces without experiencing failure, whether by rupture, fragmentation or flow. Consideration of the strength of a soil is very important, especially for agricultural purposes. There is an upper and a lower limit that is ideal for a soil, and if the strength exceeds either of these extremes, it has a detrimental effect. If a soil is too weak, it will be unable to adequately anchor the plant, as well as not being ablle to withstand the forces of wind and water. On the other hand, if a soil is too strong, plant roots, as well as organisms such as earthworms, will not have the required strength to penetrate the soil. (USYD)
