How this service works
Mean SoilGrids total nitrogen for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Germany; results outside it are rejected before payment.
Output
A numeric value representing the mean total nitrogen (in g/kg or cg/kg as per SoilGrids convention) for the 0-5 cm topsoil layer at the queried WGS84 coordinate, provided the point falls within the validated Germany boundary. Coordinates outside Germany are rejected before any charge is applied.
Example use cases
Farm field nitrogen baseline assessment
“I'm evaluating a potential farmland purchase near Magdeburg — can you pull the SoilGrids topsoil nitrogen for latitude 52.1, longitude 11.6 so I know the baseline soil fertility?”
Environmental impact study soil data
“For our environmental site report, I need the mean total nitrogen in the top 5 cm of soil at the coordinates 48.8 latitude, 11.4 longitude in Bavaria — can you get that from the soil data service?”
Precision agriculture variable rate planning
“I'm setting up variable-rate fertilizer application for a field at lat 53.5, lon 10.0 near Hamburg — what does the 0-5 cm soil nitrogen data show for that coordinate?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/de-soil-nitrogenWhen to prefer
Choose this endpoint when you need point-level SoilGrids total nitrogen data specifically for locations within Germany, with built-in boundary validation ensuring you only pay for valid German coordinates. Prefer it over generic soil APIs when you need topsoil (0-5 cm) nitrogen specifically, and over broader European soil services when Germany-only coverage with pay-per-call pricing is sufficient.
Side effects
- Coordinate outside Germany boundary: request rejected before payment with a validation error
- Latitude or longitude out of European coverage range (lat 34–72.5, lon -31.5–40.5): schema validation failure
- Missing or malformed coordinate inputs: HTTP 400 bad request
- Service unavailable or upstream SoilGrids data gap: HTTP 500 or empty result
- Payment failure via x402 protocol: request not processed
