Question Answer
a980a623-5135-4c19-a1a0-1d688078edd7.png (image/png) Soils which possess either a Bs horizon (visible dominance of iron compounds), a Bhs horizon (organic-aluminium and iron compounds), or a Bh horizon (organic-aluminium compounds). These horizons may occur singly in a profile or in combination.
202bfca8-b2af-4f3b-96ef-df5cdae282cc.png (image/png) Soils other than organosols, podsols, and vertosols in which the greater part of the profile is saturated for at least 2-3 months in most years. Wet soils in low lying plains and basins.
01681cd9-6867-4eb4-b16f-fe9c5014a0ea.png (image/png) Soils with the following: 1) A clay field texture or 35% or more clay throughout the solum except for thin, surface crusty horizons 0.03 m or less thick and. 2) When dry, open cracks occur at some 6me in most years 3) Slickensides and/or len6cular peds occur at some depth in the solum.
e6a7beb7-a490-4435-a919-3f3d5b873120.png (image/png) Soils that are not regularly inundated by saline tidal waters and have more than 0.4 m of organic materials (in upper 0.8m soils or to parent rock).
93fdbf48-48da-4704-a9fb-86960012cd34.png (image/png) Soils resulting from human activities which have led to a profound modification, truncation or burial of the original soil horizons, or the creation of new soil parent materials by a variety of mechanical means.
75f74ae5-c893-49db-af0d-91cfeafec798.png (image/png) Soils other than hydrosols with a clear or abrupt textural B horizon and in which the major part of the upper 0.2 m of the B2 horizon (or the major part of the ensure B2 horizon if it is less than 0.2 m thick) is strongly acid. The relevance of sodicity in strongly acid soils is open to question as in theory the presence of aluminium in such soils should counterbalance the usual deleterious effect of sodium (via dispersion) on soil physical properties.
d449700e-0912-4a37-9cb8-b8c76c206d58.png (image/png) Soils with a clear or abrupt textural B horizon and in which the major part of the upper 0.2 m of the B2 horizon (or the major part of the en6re B2 horizon if it is less than 0.2m thick) is sodic and not acidic.
be15f8bf-b2e0-4cf7-a693-21ab5a6e73b3.png (image/png) Soils other than Hydrosols with a clear or abrupt textural B horizon and in which the major part of the upper 0.2 m of the B2 horizon (or the major part of the en6re B2 horizon if it is less than 0.2 m thick) is not sodic or acidic.
92c4cb53-b184-4283-a992-307641bf429f.png (image/png) Soils that are calcareous throughout the solum – or calcareous at least directly below the A1 or Ap horizon, or a depth of 0.2 m (whichever is shallower). Carbonate accumulations must be judged to be pedogenic (either current or relict), and the soils do not have clear or abrupt textural B horizons.
052547ba-7e0d-4e9f-a1df-b40bb7d46323.png (image/png) Soils that: Have B2 horizons in which the major part has a free iron oxide content greater than 5% Fe in the fine earth frac6on (<2 mm), and Do not have clear or abrupt textural B horizons
416c16f9-5e92-4733-86b0-00659957c51e.png (image/png) Soils which: Have B2 horizons with structure more developed than weak throughout the major part of the horizon, and Do not have clear or abrupt B horizons
d55f19e1-a900-46e0-847f-c0006d02a396.png (image/png) Soils other than Hydrosols which have all of the following: - B2 horizons in which the major part is massive - A maximum clay content in some part of the B2 horizon which exceeds 15% - Do not have a tenic B horizon - No clear textural B horizon - Not calcereous
7778b0d7-3a8e-41b6-b259-e79be602b0ea.png (image/png) Soil with negligible (rudimentary) pedologic organisa6on apart from (a) minimal development of an Al horizon or (b) the presence of less than 10% of B horizon material (including pedogenic carbonate) in fissures in the parent rock or saprolite.
b2d42a24-86fb-4fa7-a1fd-c181afb01da0.png (image/png) Soils that do not fit the requirements of any other soil orders
