How this service works
Mean SoilGrids total nitrogen for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Greece; results outside it are rejected before payment.
Output
Returns the mean total nitrogen value from the SoilGrids dataset for the 0–5 cm surface soil layer at the queried coordinate. The response is only provided for points that fall within the Natural Earth boundary of Greece; out-of-boundary requests are rejected before any payment is charged.
Example use cases
Farmland soil fertility assessment
“I'm evaluating a plot of agricultural land near Thessaloniki — can you tell me the mean total nitrogen in the 0–5 cm soil layer at latitude 40.63, longitude 22.94?”
Vineyard site suitability check
“We're considering planting a vineyard in Crete near coordinates 35.22 latitude, 25.11 longitude — what is the topsoil nitrogen content there?”
Environmental baseline for reforestation
“Before we start a reforestation project in the Peloponnese at latitude 37.50, longitude 22.37, I need the mean surface soil nitrogen level for the 0 to 5 cm layer.”
Technical details
Endpoint
POSThttps://suedland.halowerk.com/v1/gr-soil-nitrogenWhen to prefer
Choose this endpoint when you need SoilGrids-derived mean total nitrogen specifically for a surface (0–5 cm) soil layer at a point location within Greece. It is ideal for precision agriculture, land valuation, environmental assessments, and site suitability analyses in Greece. Prefer it over generic soil APIs when you need a Greece-validated, pay-per-call micro-service with guaranteed boundary enforcement.
Side effects
- Coordinate outside Greece boundary — request rejected before payment, no result returned
- Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Missing latitude or longitude parameter — schema validation error
- Service unavailable or upstream SoilGrids data not accessible — API error
