A court dispute requires precise definition of the subject of the soil science examination. The condition of soil on a site, the quality of delivered soil and comparison of soil traces require different objects, samples and specialist knowledge.

Subject of examination

  • Soil cover, earth materials and individual samples
  • Case materials and information on sample provenance
  • Inspection, sampling and laboratory test data

Sample questions for the expert

  • Which soil properties and changes are confirmed by the materials?
  • Are the samples sufficient to answer the questions posed?
  • Which causes of changes in properties can be investigated?
  • Which sampling, storage or access limitations affect the conclusions?

The final questions are formulated according to the objects and circumstances of the particular task.

What to prepare

  • A court order or draft questions
  • Site plans, use history and documents on work performed
  • Records of sample collection, packaging and transfer
  • Laboratory test reports and previously prepared opinions

How the examination is conducted

The examination is planned around specific questions. When comparing soil traces, the provenance, preservation and comparability of comparison samples are checked separately. Ordinary site fertility or contamination testing does not replace this task.

Scope and limitations

Comparative forensic examination of soil objects requires a separate assessment of expertise and feasibility. Geobotanical description and determination of land boundaries are not automatically included in this work.

What the deliverable records

The opinion states the objects, methods, reasoned answers and limitations. Any inability to answer from the available samples is stated expressly.
