Gleyed
Gleyed is an adjective used in soil science to describe horizons that have undergone gleying, a redox process that imparts a characteristic gray coloration to the soil matrix. The term is commonly applied to horizons where prolonged water saturation reduces iron and other elements, altering color and structure.
Gleying occurs in soils that are poorly drained or periodically waterlogged. In the anaerobic conditions of
Visually, a gleyed horizon appears predominantly gray or blue-gray, often described as “gley,” and may show faint
Gleyed horizons are typical of hydric soils and wetlands, indicating prolonged saturation and poor drainage. They
