How this service works
Mean SoilGrids total nitrogen for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Estonia; results outside it are rejected before payment.
Output
A numeric value representing the mean total nitrogen content (in g/kg or cg/kg, per SoilGrids convention) for the 0–5 cm soil layer at the queried coordinate. Returns an error or rejection if the coordinate falls outside Estonia's boundary.
Example use cases
Precision agriculture soil nutrient mapping
“I'm planning crop fertilization for a field in Estonia near Tartu — can you look up the topsoil total nitrogen at latitude 58.37, longitude 26.73?”
Environmental land suitability assessment
“I need to assess soil fertility for a nature restoration project at coordinates 59.12 latitude, 24.85 longitude inside Estonia — what's the mean total nitrogen in the 0 to 5 cm layer?”
Real estate and land valuation enrichment
“Can you pull the SoilGrids topsoil nitrogen value for a parcel of land at 57.89°N, 27.01°E in Estonia to help evaluate its agricultural potential?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/ee-soil-nitrogenWhen to prefer
Use this endpoint when you need point-level SoilGrids total nitrogen data specifically within Estonia and want boundary pre-validation (so no charge for out-of-bounds queries). Prefer this over generic SoilGrids API access when you need a low-cost, pay-per-call micropayment model and Estonia is the geographic scope. Choose sibling endpoints on the same domain for other Estonian soil or land surface properties.
Side effects
- Coordinate outside Estonia boundary — request rejected before payment is processed
- Latitude or longitude outside European coverage range — schema validation error
- Coordinates on water or non-land area — may return null or rejection
- Network timeout or provider unavailability — HTTP 5xx error
- Malformed request body — HTTP 4xx validation error
