GloSIS Ontology Specification Draft

Abstract

This ontology is one of the modules comprising Global Soil Information System (GloSIS) ontology. The GloSIS ontology was developed part of the SIEUSOIL project, which aims at implementing and testing a shared China-EU Web Observatory platform that will provide Linked (Open) Data to monitor status and threats of soil and land resources. The GloSIS ontology enables the representation of soil related data in semantic format. The ontology has been derived from the UML GLOSIS data model v1.0, and it has been created in line with best practices and methodologies, reusing existing standard models and ontologies, including sosa/ssn for the representation of measurements, or SKOS for the representation of codelists.

Introduction back to ToC

This module contains the classes and properties to describe soil surfaces (a subtype of a plot with surface shape. Surfaces may be located within other surfaces).

SaltCoverc back to ToC or Class ToC

IRI: http://w3id.org/glosis/model/surface/SaltCover

Salt cover is the visible accumulation of salts on the soil surface, typically forming a crust. This can occur in areas of high evaporation, leading to the upward movement of soluble salts from deeper soil layers. Source: US Salinity Laboratory Staff. (1954).

SaltPresencec back to ToC or Class ToC

IRI: http://w3id.org/glosis/model/surface/SaltPresence

Salt presence refers to the occurrence of soluble salts within the soil, typically measured by electrical conductivity (EC) or ion concentrations (e.g., sodium, calcium). High salt concentrations can lead to soil salinity, which affects plant growth and soil structure. Source: Brady, N.C., & Weil, R.R. (2008). The Nature and Properties of Soils (14th ed.).

SaltThicknessc back to ToC or Class ToC

IRI: http://w3id.org/glosis/model/surface/SaltThickness

Salt thickness describes the depth of the soil profile where significant salt concentrations are found, which may be determined using soil core samples or electrical conductivity measurements. Salt thickness is crucial in arid regions where salt accumulation occurs due to evaporation. Source: Rhoades, J.D., & Kandiah, A. (1992). Soil Salinity Management in Agriculture. Springer.

SealingConsistencec back to ToC or Class ToC

IRI: http://w3id.org/glosis/model/surface/SealingConsistence

Sealing consistence refers to the soil's ability to resist compaction and the formation of a surface crust, often caused by wetting and drying cycles, or rainfall impact. Soils with low sealing consistence are more prone to surface sealing. Source: Soil Science Society of America (SSSA). (2008). Glossary of Soil Science Terms. Soil Science Society of America.

SealingThicknessc back to ToC or Class ToC

IRI: http://w3id.org/glosis/model/surface/SealingThickness

Sealing thickness refers to the depth of the compacted or sealed layer within the soil, which can hinder water infiltration, root growth, and soil aeration. This layer is often formed in fine-textured soils under intense rainfall or drying conditions. Source: Pagliai, M., & Vignozzi, N. (2002).

Named Individuals

saltCoverPropertyni back to ToC or Named Individual ToC

IRI: http://w3id.org/glosis/model/surface/saltCoverProperty

Salt cover refers to the accumulation of salts on the surface of the soil, often visible as a crystalline crust. This phenomenon occurs when capillary action causes soluble salts to move upwards through the soil, where they crystallize as water evaporates. Salt cover can interfere with seed germination, plant growth, and water infiltration, and is commonly found in arid and semi-arid regions with high evaporation rates.

saltPresencePropertyni back to ToC or Named Individual ToC

IRI: http://w3id.org/glosis/model/surface/saltPresenceProperty

The salt presence property of soil refers to the concentration of soluble salts, such as sodium, calcium, and magnesium, within the soil profile. High salt levels can lead to soil salinity, negatively affecting plant growth by altering water availability and soil structure. The presence of salts is typically measured using electrical conductivity (EC) or specific ion concentration tests. Soils with high salt presence are often found in arid regions where evaporation exceeds precipitation, leading to salt accumulation at or near the surface. Source: Rhoades, J.D., & Kandiah, A. (1992). Soil Salinity Management in Agriculture. Springer.

SaltThicknessPropertyni back to ToC or Named Individual ToC

IRI: http://w3id.org/glosis/model/surface/saltThicknessProperty

Salt thickness refers to the depth of the soil profile at which soluble salts are present in significant concentrations. This property is particularly important in regions subject to evaporation and capillary rise, where salts accumulate near the surface or at specific depths. Salt thickness can impact soil fertility and water retention, as the concentrated salts can inhibit root growth and water uptake. This property is commonly determined through soil sampling and electrical conductivity measurements at various depths. Source: United States Salinity Laboratory Staff. (1954).

sealingConsistencePropertyni back to ToC or Named Individual ToC

IRI: http://w3id.org/glosis/model/surface/sealingConsistenceProperty

The sealing consistence property of soil describes the resistance of the soil to the formation of a surface crust or compacted layer, which can impede water infiltration and root penetration. This phenomenon typically occurs in fine-textured soils, such as clays and silts, where the particles are tightly bound, leading to a hardened surface layer upon wetting and drying. Sealing consistence affects water movement and can lead to surface runoff and erosion in agricultural soils. Source: Soil Science Society of America (SSSA). (2008). Glossary of Soil Science Terms.

IRI: http://w3id.org/glosis/model/surface/sealingThicknessProperty

The sealing thickness property refers to the depth of the compacted or sealed layer within the soil, which is typically a result of intense rainfall, drying, or tillage practices. This layer, which forms in fine-textured soils, can significantly reduce water infiltration and root growth, leading to reduced soil aeration and potential surface runoff. The sealing thickness property is crucial for understanding soil erosion risks and water management in agricultural systems. Source: Pagliai, M., & Vignozzi, N. (2002).
