Topsoil physico-chemical properties from the Glastir Monitoring and Evaluation Programme, Wales 2013-2016
This data set includes a range of physico-chemical properties measured from topsoil within a wide range of land use types across Wales, collected as part of the Glastir Monitoring and Evaluation Programme (GMEP). The properties included are: soil organic matter (loss on ignition (LOI)), derived carbon concentration, total soil organic carbon (SOC), nitrogen, total soil phosphorous, Olsen-phosphorous (within improved land only), pH, electrical conductivity, soil bulk density of fine earth, fine e

What's in it
- Data offered docs-verified
- soil organic matter (loss on ignition, LOI) · derived carbon concentration · total soil organic carbon (SOC) · nitrogen · total soil phosphorous · Olsen-phosphorous (improved land only) · pH · electrical conductivity · soil bulk density of fine earth · fine earth volumetric water content when sampled · soil water repellency (water drop penetration time)
- Coverage docs-verified
- Wales · 2013-04-01 to 2016-10-31
- Resolution docs-verified
- Spatial resolution 10000 m (sample locations generalised to centres of 10 km OS grid squares); single topsoil samples per location, not a continuous grid

Useful for
- Use cases llm-inferred
- Baseline topsoil carbon and bulk density context for soil carbon or peat-related assessments in Welsh EIA or land-management projects · Soil water repellency and volumetric water content inputs for SuDS infiltration or runoff screening on Welsh sites · Background topsoil pH, nitrogen and phosphorus values for ecological or agricultural land-quality baselines · Soil bulk density screening input for earthworks or soil reuse assessments in Wales
- Audience llm-inferred
- ecologists · hydrologists · drainage engineers · geotechnical engineers · soil scientists · environmental consultants
Limitations
- Constraints llm-inferred
- Wales only · Fixed survey period 2013-2016; no later updates listed · Sample locations generalised to centres of 10 km OS grid squares for confidentiality · Olsen-P measured only on improved land · Topsoil cores only (15 cm long), from up to five random locations per 1 km square
