  Définition

  A mineral rich, chalk deficient, generally acid fine moder, consisting predominantly of animal droppings (of Julidae, Glomeridae, insects, small earthworm species, etc.) and their residues.

  Notes :

  The humus has a similar external appearance to mull, but it is distinguished from a true mull in that the humus and the mineral particles are present as distinctly separable elements. The binding, however, is sufficient for soil crumbs to be formed. Generally the mull-like moder can easily be distinguished from common moder by its high mineral content and from mull by its usual sandy texture, also by a certain rawness and lack of uniformity.
  
  A micro-fabric that is characterized by discrete, loosely aggregated feacal pellets generally about 0.15-0.2 mm in diameter, and brown in colout resembling those of enchytraeids. The mull-like plasma is very high in finely comminuted organic matter combined fairly intimately with any clay that is present. The fabric also contains fine mineral grains, mainly quartz, most of which are enclosed in the droppings.
  
  Mull-like moder (in a narrower sense).
  
  A term to indicate terrestric humus forms which are characterized by: - The external appearance of mull. - A relatively weak vinding tegether of organic matter and the mineral soil particles. - Little or no clay, and a relatively high percentage of silt-sized and sandsized mineral grains.
  
  Fabrics of mull-like moder humus forms (micromorphologic characteristics): leached mull-like rendzina moder, mull-like moder, mull-like rendzina moder.
