Gleization is the process by which soil forms in regions with high rainfall or in low-lying areas associated with poor drainage. This process involves the accumulation of organic matter that creates a thick, dark-colored surface layer, and an underlying layer of gray or bluish clay. The waterlogged conditions in these soils lead to the formation of anaerobic microorganisms, which produce hydrogen sulfide and other reducing agents that cause the iron in the soil to become reduced and produce the bluish-gray color.
