How this service works
Mean SoilGrids total nitrogen for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Spain; results outside it are rejected before payment.
Output
A single numeric value representing the mean SoilGrids total nitrogen concentration (likely in g/kg or cg/kg) for the 0–5 cm soil layer at the queried coordinate within Spain. Coordinates outside the Spain boundary are rejected before payment is processed.
Example use cases
Vineyard site soil fertility check
“I'm scouting a potential vineyard plot near Logroño — can you look up the SoilGrids topsoil nitrogen level for latitude 42.46 and longitude -2.45 in Spain?”
Precision agriculture planning
“For our new test field in Andalusia at 37.39 latitude and -5.99 longitude, what's the mean total nitrogen in the 0 to 5 centimetre soil layer according to SoilGrids?”
Environmental research baseline data
“I need the surface soil nitrogen reading from SoilGrids for coordinates 41.65 latitude, 0.87 longitude in Spain as a baseline for our ecosystem restoration study.”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/es-soil-nitrogenWhen to prefer
Choose this endpoint when you need point-specific SoilGrids total nitrogen data for a location confirmed to be within Spain and want a single authoritative topsoil (0–5 cm) reading. Prefer it over generic soil APIs when Spain-scoped validation, micro-payment per-call pricing, and SoilGrids provenance are required. It is part of a suite of sibling endpoints covering other soil and land-cover metrics for the same region.
Side effects
- Coordinate outside Spain boundary – request rejected before charge; returns an error indicating the point is out of coverage
- Latitude or longitude outside the accepted European range (34–72.5°N, -31.5–40.5°E) – schema validation failure
- Missing required latitude or longitude parameter – request rejected with validation error
- SoilGrids data unavailable for the specific pixel – may return null or data gap error
- Network timeout or upstream SoilGrids service unavailability
