How this service works
Mean SoilGrids total nitrogen for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Bulgaria; results outside it are rejected before payment.
Output
Returns the mean total nitrogen value (from SoilGrids) for the 0-5 cm soil depth layer at the queried coordinate. The coordinate is validated against the Natural Earth boundary for Bulgaria; if the point falls outside Bulgaria, the request is rejected before any payment is charged.
Example use cases
Agricultural site soil fertility check
“I'm evaluating a farm plot near Plovdiv, Bulgaria — can you pull the mean soil nitrogen for the 0-5 cm layer at latitude 42.15 and longitude 24.75?”
Environmental baseline for land survey
“I need to document baseline soil conditions for a nature reserve in Bulgaria at coordinates 43.2, 25.6 — specifically the total nitrogen in the surface soil layer.”
Crop suitability analysis for Bulgarian field
“We're planning a nitrogen-sensitive crop at latitude 41.98, longitude 25.33 in Bulgaria — what does SoilGrids say about the total nitrogen content in the top 5 centimeters there?”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/bg-soil-nitrogenWhen to prefer
Choose this endpoint when you need surface-layer (0-5 cm) total nitrogen data specifically for a coordinate within Bulgaria, backed by SoilGrids. It is ideal for agricultural assessment, environmental monitoring, or land suitability analysis within Bulgaria. The built-in boundary validation ensures you only pay for valid Bulgarian coordinates. Prefer alternatives if you need nitrogen data for other countries, deeper soil horizons, or other soil properties.
Side effects
- Coordinate outside Bulgaria boundary — request rejected with boundary validation error before payment
- Latitude or longitude out of the stated European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Missing latitude or longitude parameters — request rejected with input validation error
- SoilGrids data unavailable for the given coordinate — no data returned
- Network timeout or service unavailability — HTTP 5xx error
