Reference soil Slovakia 07: Gleysol

SK007

Gleysols occur throughout the world where groundwater comes near to the surface, causing soils to become wet for a prolonged part of the year. They are particularly abundant in the low-lying river basins.

Characteristics

Soils having gleyic properties (properties associated with prolonged wetness) within 50 cm from the soil surface. They have no diagnostic horizons other than an anthraquic, histic, mollic, ochric, takyric, or umbric horizon at the surface, or an andic, calcic, cambic, gypsic, plinthic, salic, sulfuric, or vitric horizon within 100 cm from the soil surface.
