What it is Derived, awaiting review

This meta-model describes soil as a mapped, sampled and classified resource and the agricultural capability that follows from it: profiles and horizons, laboratory chemistry and physical properties, capability and suitability ratings, and the degradation, contamination and management history that change land condition over time.

Note: First sentence of the legacy card introduction.

Why it exists Filled

Soil quality and agricultural capability

Distinguishing features Derived, awaiting review

  • It is its own model because soil is a slow-moving stock that is measured at points, mapped as units and managed as fields, three grains that must be reconciled explicitly.

Owners Filled

Steward

An ecology and agronomy commons steward keeps the soil register: it maintains the map, accredits laboratories, publishes capability and condition and curates the long profile archive.

Links to other meta-models Filled

references

  • world.landParcelAndCadastre - fields and units are located within registered land units and their holders resolve there
  • world.terrainAndLandform - slope, aspect and relief are limiting factors in capability and erosion assessment
  • world.subsurfaceAndMineralResource - parent material links the weathering profile to bedrock
  • world.waterBodyAndHydrology - infiltration, runoff and nutrient loading connect soil state to water response
  • world.ecosystemAndBiome - soil condition is an input to ecosystem condition and process accounts
  • world.agricultureAndHusbandry - cropping, grazing and amendment operations are described there and reference fields here
  • world.materialAndSubstance - contaminant identity, hazard class and thresholds resolve there
  • world.emissionAndEnvironmentalFlux - soil carbon change and nutrient losses are accounted as fluxes there
  • world.officialStatisticsAndIndicators - published land statistics respect the cohort grain defined there
  • world.privacyAggregationAndCohortFloor - published land statistics respect the cohort grain defined there

What else AI and robots need to interact with it Incomplete

Identity and identifiers required Derived, awaiting review

  • soilUnit: a mapped soil unit; key attributes: unit identifier, geometry, dominant classification term, component proportions, map scale, purity
  • soilSample: material taken for analysis; key attributes: sample identifier, source horizon reference, depth interval, sampling date, laboratory reference, analysed determinands

Direct properties not applicable Not applicable

Not applicable

Institutional or informational subject: no invented physical properties.

Recognition optional Missing, in the backlog

Not described yet. This gap is in the card backlog.

Capabilities and actions required Derived, awaiting review

  • soilProfileDescribed: a pit or auger site was described and classified
  • soilSampleAnalyzed: laboratory results were returned and attached to a horizon
  • soilMapUnitRevised: unit boundaries or component proportions changed after new evidence
  • capabilityClassReassessed: the general capability rating for a unit changed
  • erosionEventRecorded: a measurable loss of topsoil was observed after rainfall, wind or cultivation
  • salinizationDetected: salinity crossed the threshold defined for a unit or field
  • contaminationConfirmed: a contaminant exceeded its threshold at a sampled location
  • remediationCompleted: works to restore soil condition finished and post-works results were recorded

Legacy events listed as state transitions.

Hazards and failure modes optional Missing, in the backlog

Not described yet. This gap is in the card backlog.

Standards and interfaces required Derived, awaiting review

  • laboratoryAnalysisContract: terms for submitting samples and returning results, including method declaration, detection limits and reanalysis
  • farmSoilDataSharingContract: terms under which field-level results held by a holder are shared with the steward, including the grain at which they may be republished
  • contaminationDisclosureContract: terms for disclosing a confirmed contamination finding to an entitled party such as a prospective occupier or a land registrar
  • publicSoilMap: soil units, dominant classification and capability class; omits sample-level results and any holder-linked field data
  • holderFieldReport: the complete profile, laboratory and condition record for the fields of one holder; omits neighbouring holdings
  • landCapabilityStatistics: area by capability class, suitability and degradation status; omits unit geometry and holder identity

Context of use required Filled

  • Field-level data contributed by a holder remains that holder's under S1, republication happens only at the grain agreed in an S2 access contract and constrained by S5 cohort rules, and reads of holder-linked records are logged in S4.

Sources Missing, in the backlog
