Package ANZSoilML.ANZSoilML_Soil

Notes:The ANZSoilML_Soil Package contains classes representing notional soil units, soil profiles and soil layers whose complete and precise extent is inferred to exist. Explicit spatial properties are available through association with a SpatialEntity via the AbstractSoil generalization.

Soils includes both formal units (i.e. formally adopted and named in the official lexicon) and informal units (i.e. named but not promoted to the lexicon) and unnamed units (i.e. recognisable and described and delineable in the field but not otherwise formalised).

Class Summary

<<FeatureType>>AbstractSoilName: AbstractSoil

AbstractSoil is an abstract soil domain feature that provides a link between the SoilFeatures and the Landscape features, via landscapeContext, the spatial distribution of the SoilFeatures via the occurrence property, and the metadata properties.

<<FeatureType>>PedsPeds is a specialization of SoilMaterial to allow describing individual natural soil aggregates consisting of a cluster of primary particles (peds). Peds are separated from adjoining peds by surfaces of weakness that are recognizable as natural voids or by the occurrence of cutans (ASLS Field Handbook p 171).

Properties different from those of SoilMaterials include the ped type (platy, prismatic, columnar, angular blocky), and the grade (degree of development and distinctness of peds, e.g. single grain, massive, weak, moderate, strong).

Inherited property particleGeometry:particleType is used to specify that the particle is an artificial fragment of type 'clod' or 'fragment' and its ConstituentPart:role is ped.
ConstituentPart:relatedMaterial is used to identify parting between peds.
<<CodeList>>PedTypeTermTerms to describe the type of Ped

<<CodeList>>SegregationTypeTermTerms to describe the nature of the segregations ASLS Field Handbook p196
<<FeatureType>>SoilSoil is a natural body consisting of layers (soil horizons or layers) of primarily mineral constituents of variable thicknesses, which differ from the parent materials in their texture, structure, consistence, colour, chemical, biological and other physical characteristics
(after wikipedia).
<<CodeList>>SoilClassificationTermA term from an appropriate soil classification (In Australia the 'Australian Soil Classification").
<<FeatureType>>SoilFeatureThe abstract SoilFeature class represents a conceptual feature that is hypothesized to exist coherently in the world.
* this corresponds with a "Soil Unit", comprising a set of similar soil profiles with a mappable distribution in some "Soil Landscape", a Soil Profile or its constituent parts;

The implemented SoilFeature instance acts as the "description package"

* the description package is classified according to its purpose as an Instance, TypicalNorm, or DefiningNorm.
<<FeatureType>>SoilHorizonA SoilHorizon is a layer of soil, approximately parallel to the land surface, with mostly homogenous morphological properties different from layers below and/or above it. (p148)
Distinguished from SoilLayers in that it is developed in a parent material layer through pedogenic processes or made up of in-situ sedimented organic residues of up-growing plants (peat) (INSPIRE), and therefore can be classified with a horizon notation.
<<FeatureType>>SoilLayerDocumentation from INSPIRE:
-- Name --
Soil layer

-- Definition --
domain of a soil with a certain vertical extension developed through non-pedogenic processes, displaying an unconformity to possibly over- or underlying adjacent domains.

-- Description --
NOTE1 Different kinds of layer concepts are covered by this definition.

EXAMPLE 1 Geogenic layers: These are domains, resulting from e.g. sedimentation (as non-pedogenic) processes, that display an unconformity to possibly over- or underlying adjacent domains.

EXAMPLE 2 Topsoil and Subsoil: These can be domains that group different soil horizon types (e.g. A vs. B horizons), or a special case of fixed depths with only two depth ranges (e.g. 0-15 cm: topsoil and, 15-75 cm: subsoil).

EXAMPLE 3 Depth intervals: They are often used in soil monitoring, sampling of contaminated sites and in modelling and include: (i) depth increments (also called fixed depths) that are often used for sampling, e.g. 0-30cm, 30-60cm, and so on, (ii) a single depth range in which a soil sample (”specimen”) is taken and for which the analytical result is valid, and (iii) soil slicing, that is, profile segmentation according to a specified vector, for instance, either regularly spaced intervals (1cm), or a user-defined vector of segment boundaries (i.e. 0-10, 10-25, 25-50, 50-100). Slicing is used in modelling to generate continuous depth functions for soil properties.

EXAMPLE 4: In the framework of soils deeply modified by human activity, artificial layers may be due to different kinds of deposits (concrete, bricks, …).

For OzSoilML a Soil Horizon is considered a further specialization of a SoilLayer
<<type>>SoilMaterialThe physical properties and appearance of the soil
<<CodeList>>SoilObservationMethodTermSoilObservationMethodTerm is aterm from a vocabulary indicating how the soil feature was determined.
(eg: soil pit, existing vertical exposure, undisturbed soil core, auger boring, outcrop)
<<DataType>>SoilPanA pan is an indurated and/or cemented soil horizon (ASLS Field Handbook p192).
However, treated as property of SoilLayer in OzSoilML as NatSoil doesn't record depth of Pan, often doesn't assign Horizon identifiers.
<<FeatureType>>SoilProfile-- Name --
soil profile

-- Definition --
description of the soil that is characterized by a vertical succession of profile elements.

-- Description --
NOTE The soil profile is abstracted from observations in a trial pit or a boring, or derived from expert knowledge using other soil profiles.
<<FeatureType>>SoilProfileElementThe elements that make up the Soil Profile
SoilRelationshipThe SoilRelationship class is used to define relationships between soilfeatures, ie. SoilProfile-SoilProfile, Soil-Soil relationships.

Relationships are always binary and directional. There is always a single source and a single target. The relationship is always defined from the perspective of the Source and is generally an active verb.

Example: a Source may point to a Soil forming a component of a soil complex. In this case, the Target would point to the appropriate Soil representing the complex and the relationship attribute would be 'soil complex component'. Other appropriate relationship attributes might include: catena component, buried soil

Two or more SoilFeatures are associated in aSoilRelationship; each has a role in the relationship. Examples of soil roles include "component part", "complex soil", "overlies", "underlies", "catena part", and so forth.
<<CodeList>>SoilRelationshipTermTerm to describe the relationship between two Soil Features.
SoilSubstrateRelationshipDescribes the relationship between the Substrate and the Soil
<<FeatureType>>SoilSurfaceThe Soil as it appears at the surface.
This can be considered as analogous to a Soil Layer with a depth of 0.
<<CodeList>>SoilSurfaceConditionTermTerms to describe the condition of the soil surface when dry
ASLS Field Handbook p189
<<FeatureType>>SoilThematicObject-- Name --
soil thematic object

-- Definition --
spatial object representing a soil related property derived from one or more soil properties.

-- Description --
NOTE Soil thematic maps can be derived directly from the involved soil database (organic matter content, pH, texture, etc.) or they can be derived by using Pedotransfer Functions (water availability…).
<<CodeList>>SoilThematicPropertyTerm-- Name --

-- Definition --
Terms from a vocabulary that are appropriate to describe the soil related property that the soil thematic results relate to within the soil thematic object.

The SoilThematicPropertyTerms shall be a phenomenon associated with soil features.
<<CodeList>>StickinessTermASLS Field Handbook p187
<<CodeList>>StrengthTermStregth of segregations
ASLS Field Handbook p197
<<FeatureType>>SubstrateMaterial and mass of the earth or rock that do not show pedological development. They are not soils but typically underlie them. The substrate includes the R horizon and that part of the C horizon that shows no pedological development. The substrate beneath the soil may or may not be the parent material of the soil.
The Substrate is clearly related to the GeoSciML GeologicUnit. However, as the observations typically made on the substrate by soil scientists are different to those made by geologists, it is considered a separate class here. Future harmonization between domains should resolve these differences.
<<CodeList>>TextureQualificationTermTerms to qualify the non-clay field texture grades.
These terms should probably be combined with the Texture grade classification, as per the clay textures.
ASLS Field Handbook p166
<<type>>VoidVoid is a general term for pore space and other openings in soils not occupied by solid mineral matter
<<CodeList>>WaterRepellenceTermTerms to describe the water repellence properties of the soil.
ASLS Field Handbook (p191)
