What is the meaning of word Gleyed?

Gleyed is an adjective that refers to soil that has been affected by the process of gleying. Gleying is a soil-forming process that occurs in poorly drained conditions, such as in wetlands. It involves the reduction and accumulation of iron and manganese oxides, which gives the soil a bluish or greenish-gray color. Gleyed soils are often found in areas with high rainfall or flooding, and they can have poor drainage and fertility.
