6 Table A-2b Soil Horizon Symbol Definitions Symbol Major Mineral Horizon Symbol (a) A B C Definition This mineral horizon forms at or near the surface in the zone of leaching or eluviation of materials in solution or suspension, or of maximum in situ accumulation of organic matter or both. This mineral horizon is characterized by enrichment in organic matter, sesquioxides, or clay; or, by the development of soil structure; or, by a change of colour denoting hydrolysis, reduction, or oxidation. This mineral horizon is comparatively unaffected by the pedogenic processes operating in A and B horizons. Lowercase Mineral Horizon Suffix g h j m y z 1 A horizon characterized by gray colours, or prominent mottling, or both, indicating permanent or periodic intense reduction. A horizon enriched with organic matter. A modifier used to denote an expression of, but failure to meet, the specified limits of the suffix it modifies. A horizon slightly altered by hydrolysis, oxidation, or solution, or all three to give a change in colour or structure, or both. A horizon affected by cryoturbation as shown by disrupted and broken horizons, incorporation of materials from other horizons, and mechanical sorting in at least half of the cross section of the pedon. A frozen layer. Uppermost subdivision is indicated by the numeral 1; each successive subdivision with depth is indicated by the next numeral. A second subdivision is indicated by the numeral 2; each successive subdivision with depth is indicated by the next 2 numeral. Major Organic Horizon Symbol (b) Organic horizon developed mainly from mosses, rushes, and woody materials, and divided into the following O subhorizons. Organic Subhorizon Code Of Om This O horizon consists largely of fibric materials that are readily identifiable as to botanical origin. A fibric horizon has 40% or more of rubbed fiber by volume and a pyrophosphate index of 5 or more. Fibric material usually is classified on the von Post scale of decomposition as class 1 to class 4. This O horizon consists of mesic material, which is at a stage of decomposition intermediate between fibric and humic materials. The material is partly altered both physically and biochemically. It has a rubbed fiber content ranging from 10% to less than 40%, and has a pyrophosphate index of >3 and <5. Mesic material usually is classified on the von Post scale of decomposition as class 5 or 6. Source: SCWG (1998). a) Mineral horizons contain 17% or less organic carbon (about 30% organic matter) by weight. b) Organic horizons occur in organic soils and commonly at the surface of mineral soils. They may occur at any depth beneath the surface in buried soils or overlying geologic deposits. They contain more than 17% organic carbon (about 30% or more organic matter) by weight. Two groups of these horizons are recognized, the O horizons (peat materials) and the L, F, and H horizons (folic materials). % = percent; < = less than; > = greater than. A-4
