##### Definition

Grade of pedality is the degree of development and distinctness of peds. In virtually all material that has structure, the surface of individual peds will differ in some way from the interior of peds. The degree of development expresses the relative difference between the strength of cohesion within peds and the strength of adhesion between adjacent peds. Determination of grade of structure in the field depends on the proportion of peds that hold together as entire peds when displaced and also on the ease with which the soil separates into discrete peds. Grade of pedality varies with the soil water status. It is important to record the soil water status of the described profile, and it is desirable that the grade of pedality be described at the soil water status most common for the horizon.
