How this service works
Mean SoilGrids bulk density for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Poland; results outside it are rejected before payment.
Output
Returns the mean bulk density value (g/cm³ or cg/cm³ as per SoilGrids convention) for the 0–5 cm topsoil layer at the queried coordinate. If the coordinate falls outside the validated Poland boundary, the request is rejected before payment is processed.
Example use cases
Agricultural soil compaction assessment
“I need the mean topsoil bulk density for the 0-5 cm layer at my field site in central Poland — latitude 51.9194, longitude 19.1451. I want to understand soil compaction before deciding on tillage practices.”
Construction site ground survey
“Can you check the SoilGrids bulk density of the shallow topsoil layer at coordinates 50.0647° N, 19.9450° E near Kraków? I need it for a pre-construction soil assessment.”
Environmental model data enrichment
“I'm building a runoff model and need the 0-5 cm soil bulk density value for a monitoring point at 54.3520° N, 18.6466° E in northern Poland near Gdańsk — can you pull that from SoilGrids?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/pl-soil-bulk-densityWhen to prefer
Use this endpoint when you need SoilGrids topsoil bulk density specifically for a location within Poland, and want boundary-validated results with per-call micropayment pricing. Prefer it over direct SoilGrids API calls when you need guaranteed coordinate rejection outside Poland and don't want to manage authentication or spatial validation yourself.
Side effects
- Coordinate outside Poland boundary: request rejected before payment, no result returned
- Coordinate outside European coverage range (lat 34–72.5, lon -31.5–40.5): validation error
- Missing or malformed latitude/longitude: schema validation error
- SoilGrids data unavailable for remote or unmapped location: may return null or error
