| CODE | NAME | DESCRIPTION | VALID_HOR_MASTER | FROM_YEAR | TO_YEAR |
|---|---|---|---|---|---|
| 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 |
