  1. 1Gleysol diagnostic designation is a [blank_start]g[blank_end]. Gleying must occur within the top [blank_start]50[blank_end]cm of the soil surface.

    Other key characteristics:
    Chroma [blank_start]<1[blank_end] or hues bluer than [blank_start]10Y[blank_end].
    Prominent mottles [blank_start]>2%[blank_end] of area.
    If hue is redder than 5YR, chroma [blank_start]<2[blank_end]
    If hue is yellower than 10YR, chroma [blank_start]<3[blank_end].

    - [blank_start]Water saturation[blank_end] to the surface for at least a [blank_start]month[blank_end] without being [blank_start]frozen[blank_end].
    - Can have an [blank_start]organic[blank_end] horizon ([blank_start]<40cm[blank_end] Om/Oh or [blank_start]<60cm Of[blank_end])
    - [blank_start]Hydrophytic[blank_end] vegetation, such as [blank_start]willows[blank_end] [blank_start]sedges[blank_end], [blank_start]spike rush[blank_end], etc.,
