How this service works
Mean SoilGrids total nitrogen for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Belgium; results outside it are rejected before payment.
Output
A numeric value representing the mean total nitrogen concentration in the 0–5 cm topsoil layer at the queried coordinate, sourced from SoilGrids. The coordinate is first validated against the Natural Earth boundary for Belgium; requests falling outside Belgium are rejected before any charge is applied.
Example use cases
Precision agriculture soil assessment
“I'm evaluating a farm plot near Ghent — can you get me the topsoil nitrogen reading for latitude 51.05, longitude 3.72? I need to know the SoilGrids nitrogen level for the 0-5 cm layer.”
Environmental impact baseline study
“We're doing an environmental baseline for a construction project in Liège — please fetch the mean soil nitrogen content at latitude 50.64, longitude 5.57 for the 0-5 cm surface layer.”
Land quality scoring for real estate
“I'm comparing agricultural land parcels in the Ardennes. Can you pull the topsoil nitrogen value for latitude 50.22, longitude 5.68 so I can include it in the land quality report?”
Technical details
Endpoint
POSThttps://atlantikland.halowerk.com/v1/be-soil-nitrogenWhen to prefer
Use this endpoint when you need point-level SoilGrids total nitrogen data specifically for locations within Belgium. It is ideal for precision agriculture, land valuation, environmental assessments, and soil fertility analyses where a pre-validated, pay-per-call lookup is preferable to managing direct SoilGrids API access. The built-in Belgium boundary validation ensures you are not charged for out-of-scope queries.
Side effects
- Coordinate outside Belgium boundary — request rejected before payment with a validation error
- Coordinate within European bounding box but outside Belgium polygon — boundary check failure
- Latitude or longitude outside the declared European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- SoilGrids data unavailable for the specific grid cell — may return null or error
- Malformed request body missing required latitude or longitude fields
