Granular

A soil ped, which is sub-divided into Granular and Crumb, having rounded surfaces and is common in topsoil (A Horizons). A Granular structure is relatively small and compact within an aggregate, being less porous than a Crumb structure which is more porous, and this is represented by a good topsoil that has good organic matter content and an active soil fauna and micro-organisms. This is the best structure for most soils, especially turfculture.
