an actinomycetes Histic organo-mineral horizon, mostly formed by microorganisms (actinomycetes), dark coloured, with plastic and massive structure, both high and low base saturation is possible A 1984  
l limnic HS horizon with a high percentage of mineral particles (clay, silt and sand). The mineral fraction is more than 50%. The mineral component may occur in the form of thin layers. The bioactivity is comparable to szoH HS 1984  
ma biomacrostructured mixed biogenic organo-mineral peds dominate A 1984  
me biomesostructured composed of coloured organic (dark) or/and organo-mineral biogenic peds A 1984  
mi biomicrostructured composed of fine mineral grains mixed with fine organic particles and dark-coloured biogenic peds (holorganic or hemiorganic) A 1984  
ms massive structure material is a coherent mass (but not necessarily cemented), biological aggregation absent or involving less than 5% of the soil volume A 1984  
n new new litter (age<1year), neither fragmented nor transformed/discoloured leaves and/or needles OL 1984  
noz non-zoogenic To the naked eye, or with the help of a hand lens, this horizon does not show relevant signs of animal activity (absence of burrows; droppings, mucus coatings, animal remains, etc. < 5% of soil volume). Zoological agents are not involved in soil aggregation. Fungus- and root-derived aggregates can be visible. OF, OH, HS, A 1984  
sg single grain structure entirely non-coherent (e.g., loose sand), biological aggregation absent or involving less than 5% of the soil volume A 1984  
szo slightly zoogenic   OH 1984  
v vetustus, verändert, verbleicht or viellie old litter (age>3 months), slightly altered, discoloured, bleached, softened up, glued, matted, skeletonized, sometimes only slightly nibbled by fauna OL 1984  
zo zoogenic   OF, OH, HS, A 1984
