  Définition

  A pedotubule is a pedological feature consisting of soil material (skeleton grains or skeleton grains plus plasma, as distinct from concentrations of the plasma), and having a tubular external form, either single tubes or branching systems of tubes; the external boundaries are relatively sharp.

  Notes :

  Most pedotubules are crotovinas.
  
  A type of bioformations.
  
  Terms indicating the degree of adhesion of a feature to the encasing soil material (used for the description of e.g. cutans, glaebules and pedotubules): discrete, weakly adhesive, moderately adhesive, strongly adhesive.
  
  Kinds of pedotubules according to internal fabric: aggrotubule, lowstructure, chamber pedotubules, cleavage striotubule, compound pedotubule, fragmotubule, granotubule, isotubule, modexotubule, scatotubule, scato-striotubule, segmented isotubule, segmented striotubule, striotubule.
  
  Other important characteristics of pedotubules are: the composition of the plasma, external form (e.g. branching patterns) and distinctness.
  
  On the basis of origin of the composing material pedotubules can be classified into: orthotubules, metatubules, paratubules.
