Particle Size Distribution measurements for 419 archived topsoil samples from arable and grassland habitats across Great Britain in 2007. Laser granulometry was used to derive aggregate stability metrics from the difference in Mean Weight Diameter before and after sonication. The data was collected by the Countryside Survey monitoring programme to study soil quality indicators across agricultural land management gradients.
Use Cases
- Analyze the relationship between Mean Weight Diameter differences and soil aggregate stability across different habitats.
- Model soil quality indicators using Particle Size Distribution measurements from the 419 archived topsoil samples.
- Compare aggregate stability metrics between arable and grassland habitats sampled across Great Britain.
- Investigate how soil resistance to perturbations varies based on laser granulometry measurements of 1–2 mm aggregates.
Strengths
- Contains measurements from 419 distinct topsoil samples.
- Data originates from the Countryside Survey, a long-term monitoring programme of UK natural resources.
- Includes derived aggregate stability metrics calculated from laser granulometry.
Limitations
- Limited to a single year (2007), providing a snapshot rather than temporal trends.
- Sample size of 419 may limit granular geographic or habitat-specific analysis.
- Aggregate stability is inferred from a single method (difference in Mean Weight Diameter), which may not capture all stability dynamics.
