How this service works
Mean SoilGrids pH in H2O for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Sweden; results outside it are rejected before payment.
Output
A numeric mean soil pH value (H2O method) for the 0-5 cm topsoil layer at the queried coordinate, derived from SoilGrids global soil property maps and validated to fall within Sweden's Natural Earth boundary.
Example use cases
Crop suitability assessment for Swedish farmland
“I'm planning to grow blueberries on a plot near Dalarna — can you check the soil pH at latitude 60.5, longitude 15.3 in Sweden to see if the acidity is right for them?”
Forestry site characterization in northern Sweden
“We're evaluating a reforestation site in Norrland at coordinates 66.1°N, 20.5°E — what does the topsoil pH look like there according to SoilGrids?”
Environmental baseline report for a Swedish land parcel
“I need the soil pH reading for the top 5 cm at a site in Skåne, coordinates 55.7 latitude and 13.2 longitude, for an environmental baseline document.”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/se-soil-phWhen to prefer
Choose this endpoint when you need a single, authoritative SoilGrids topsoil pH (H2O) value for a specific point in Sweden and want boundary validation ensuring coordinates are within the country. It is optimized for Swedish territory, costs $0.004 USDC per call, and pre-validates coordinates against Sweden's Natural Earth boundary before charging, making it preferable to generic global soil APIs when the use case is specifically Swedish land analysis.
Side effects
- Coordinate outside Sweden boundary — request rejected before payment is processed
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Invalid or missing coordinate fields — schema validation failure
- Coordinate within European bounding box but outside Sweden polygon — boundary rejection
