Question 6

Explain the formation and properties of Gley soil.

Answer 6

vegetation is limited,
mor humus is thin and acidic
few soil biota survive due to cold climate, resulting in defined horizons
Gley is waterlogged due to being flat surfaces, with snowmelt
this creates anaerobic conditions which causes iron compounds to turn from red/brown to blue
Gley is found in areas where precipitation is greater than evaporation,
the parent material is variable and may be glacial till
