Monthly chemical soil solution data from 46 Swiss forest sites collected since 1997. The sites cover gradients in elevation (290-1870 m), precipitation (915-2211 mm), and nitrogen deposition (10-81 kg ha⁻¹a⁻¹). Measurements include pH, conductivity, anions, cations, and DOC, providing a basis for assessing forest soil quality changes.
Use Cases
- Modeling soil acidification trends based on pH and cation/anion measurements.
- Assessing nitrogen leaching and deposition impacts based on NO₃⁻ and NH₄⁺ concentrations.
- Evaluating critical thresholds for forest health based on BC/Al ratios and pH values.
- Correlating soil solution chemistry with environmental gradients like elevation and precipitation.
Strengths
- Long-term monthly monitoring since 1997.
- 46 sites covering a broad range of Swiss forest conditions.
- Detailed chemical indicators including pH, anions, cations, and DOC.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
