How this service works
Mean SoilGrids pH in H2O for the 0-5 cm layer. The service evaluates the bounded polygon supplied by the caller and returns standardized units across all 30 covered countries.
Output
A standardized mean soil pH value (H2O method) for the 0–5 cm depth layer, aggregated over all SoilGrids raster pixels falling within the submitted polygon. The result is consistent across all 30 covered European countries.
Example use cases
Crop suitability check for new farmland
“I'm evaluating a field near Poznań, Poland for potato farming — can you get the SoilGrids topsoil pH for the polygon with corners at [16.92, 52.41], [16.95, 52.41], [16.95, 52.39], [16.92, 52.39]? I need to know if the soil acidity is suitable.”
Vineyard site selection in southern France
“We're considering two plots for a new vineyard in Languedoc. Can you pull the mean soil pH for the 0–5 cm layer for the polygon [3.21, 43.58], [3.24, 43.58], [3.24, 43.56], [3.21, 43.56] so we can compare acidity levels?”
Carbon credit land audit in the Netherlands
“For a carbon sequestration project audit, I need the baseline topsoil pH reading for a parcel near Wageningen — coordinates are [5.66, 51.97], [5.69, 51.97], [5.69, 51.95], [5.66, 51.95]. Please fetch the SoilGrids H2O pH for the 0–5 cm layer.”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-soil-ph-parcelWhen to prefer
Choose this endpoint when you need standardized SoilGrids topsoil pH data for a precise, user-defined polygon boundary within Europe — especially for agricultural due diligence, precision farming, environmental assessments, or land valuation workflows where a parcel-level (rather than circular buffer) query is required. Prefer this over point-based or circular-buffer soil APIs when exact cadastral or field boundaries are available.
Side effects
- Polygon exceeds 0.25-degree maximum span — returns validation error
- Fewer than 3 coordinate pairs provided — polygon invalid
- Coordinates outside supported European bounding box (lon: -31.5 to 40.5, lat: 34 to 72.5) — out-of-coverage error
- Malformed coordinate array (non-numeric values, wrong nesting) — schema validation failure
- No SoilGrids data available for very remote or island areas — may return null or empty result
