How this service works
Mean SoilGrids total nitrogen for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Hungary; results outside it are rejected before payment.
Output
A single numeric value representing the mean total nitrogen content (in g/kg or cg/kg per SoilGrids convention) for the 0-5 cm topsoil layer at the queried coordinate, derived from the SoilGrids dataset. The coordinate is validated against Hungary's Natural Earth boundary; coordinates outside Hungary are rejected before any charge is applied.
Example use cases
Precision agriculture soil assessment
“I'm evaluating farmland near Debrecen, Hungary — can you look up the mean total nitrogen in the top 5 cm of soil at latitude 47.53, longitude 21.63 so I can assess its fertility baseline?”
Environmental research site characterization
“For my wetland study site in Hungary at coordinates 46.72 north, 17.88 east, I need the SoilGrids mean total nitrogen for the 0-5 cm layer to characterize baseline soil conditions.”
Land suitability screening for investors
“We're considering a parcel near Győr, Hungary at latitude 47.68, longitude 17.65 — can you fetch the topsoil total nitrogen value from SoilGrids so we can factor soil quality into our land valuation?”

Endpoint
POSThttps://ostland.halowerk.com/v1/hu-soil-nitrogenWhen to prefer
Use this endpoint when you specifically need SoilGrids total nitrogen data for the 0-5 cm topsoil layer at a point location within Hungary. It is the right choice for precision agriculture, land evaluation, environmental assessments, or soil science workflows scoped to Hungarian territory. For other soil properties (e.g., cation exchange capacity, coarse fragment volume) or other countries, use the corresponding sibling endpoints on ostland.halowerk.com.
Side effects
- Coordinate outside Hungary boundary: request rejected before payment with a boundary validation error
- Coordinate within European coverage range but outside Hungary: rejected by Natural Earth boundary check
- Latitude or longitude out of the European bounds (lat 34–72.5, lon -31.5–40.5): schema validation error
- Missing latitude or longitude: request rejected with a missing-parameter error
- Network or upstream SoilGrids data unavailability: service error response
