How this service works
Mean SoilGrids cation exchange capacity for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Denmark; results outside it are rejected before payment.
Output
A numeric mean cation exchange capacity value (cmolc/kg or equivalent SoilGrids unit) for the 0–5 cm soil layer at the requested coordinate, derived from SoilGrids data and validated to be within Denmark's Natural Earth boundary.
Example use cases
Agricultural soil fertility assessment
“I'm evaluating a farm plot near Aarhus — can you pull the topsoil cation exchange capacity for latitude 56.163, longitude 10.203 so I know how well the soil holds nutrients?”
Environmental site characterisation
“I need the SoilGrids CEC value for the 0-5 cm layer at coordinates 55.40, 8.90 in Denmark for a contamination risk report I'm preparing.”
Precision agriculture input planning
“Before recommending fertiliser rates for a Danish field, I need the mean cation exchange capacity of the topsoil at latitude 55.85, longitude 9.72 — can you get that for me?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/dk-soil-cecWhen to prefer
Choose this endpoint when you specifically need SoilGrids-derived mean CEC for the 0–5 cm topsoil layer at a point location within Denmark. It is ideal for agricultural, environmental, or geospatial workflows requiring standardised, boundary-validated soil nutrient-retention data for Danish coordinates. Use sibling endpoints on the same platform for other soil properties (pH, organic carbon, texture class) or for elevation and terrain metrics.
Side effects
- Coordinate outside Denmark boundary — request rejected before payment is processed
- Latitude or longitude out of the published European coverage range (34–72.5°N, -31.5–40.5°E) — validation error
- Invalid or missing coordinate fields — schema validation failure
- SoilGrids upstream data unavailable for the queried location — no-data response
