Great Britain soil data provides model-estimated mean values for topsoil carbon metrics within specific habitat and parent material combinations, derived from the 2007 Countryside Survey. The analysis is based on 2,614 soil cores collected from 591 one-kilometer squares, with estimates for loss-on-ignition, carbon concentration, and carbon density.
Use Cases
- Model carbon density (t ha-1) across different Broad Habitat types for carbon stock mapping.
- Analyze the relationship between Loss on ignition (%) and estimated carbon concentration (g kg-1) by parent material.
- Compare topsoil carbon metrics from the 2007 survey against historical 1978 and 1998 Countryside Survey data trends.
Strengths
- Data is derived from 2,614 physical soil cores, providing a substantial sample base.
- Spatially representative, covering 591 one-kilometer squares across Great Britain.
- Includes three key carbon metrics: Loss-on-ignition, carbon concentration, and carbon density.
Limitations
- Urban and littoral rock areas were not sampled, creating geographic gaps in coverage.
- Some habitat and parent material combinations had insufficient sample sizes for reliable mean estimates.
