Oxygen availability in soils is largely defined by drainage characteristics of soils. The determination of soil drainage classes is based on procedures developed at FAO (FAO 1995). These procedures take into account soil type, soil texture, soil phases and terrain slope. Apart from drainage characteristics, the soil quality of oxygen availability may be influenced by soil and terrain characteristics that are defined through the occurrence of specific soil phases. These include for the FAO 74 classification soil phases indicating phreatic conditions, and for the FAO 90 classification soil phases indicating respectively phreatic, anthraquic, inundic, or placic conditions. Soil qualities have been estimated for the sequence 1 soils [...]
