How this service works
Mean SoilGrids total nitrogen 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
A numeric value representing the mean SoilGrids total nitrogen content (in g/kg or cg/kg) for the 0-5 cm topsoil layer at the queried coordinate. The response is only returned for coordinates that pass validation against the Natural Earth boundary of Poland; out-of-boundary coordinates are rejected before any charge is applied.
Example use cases
Agricultural field fertility assessment
“I'm evaluating a farming plot near Poznań — can you look up the topsoil nitrogen level at latitude 52.41, longitude 16.93 in Poland?”
Environmental soil quality monitoring
“For a nature reserve monitoring project, I need the mean total nitrogen in the 0-5 cm soil layer at coordinates 50.06 latitude, 19.94 longitude in Poland.”
Precision agriculture input planning
“We're planning fertilizer applications and need to know the baseline soil nitrogen at latitude 51.75, longitude 19.45 — that's a field in central Poland.”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/pl-soil-nitrogenWhen to prefer
Choose this endpoint when you need point-level SoilGrids total nitrogen data specifically for locations within Poland and want coordinate boundary validation built in before payment. It is ideal for agricultural analysis, environmental monitoring, or land-use planning workflows focused on Poland. Prefer this over generic SoilGrids API calls if you want pay-per-query pricing with automatic Poland-boundary enforcement and consistent topsoil (0-5 cm) depth standardization.
Side effects
- Coordinate outside Poland boundary — request rejected before payment, error indicating invalid location
- Latitude or longitude out of the European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Missing required latitude or longitude — schema validation failure
- SoilGrids data unavailable for remote or edge-boundary locations — null or error response
- Network timeout or service unavailability — HTTP 5xx error
