How this service works
Mean SoilGrids total nitrogen for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Slovenia; results outside it are rejected before payment.
Output
A numeric value representing the mean total nitrogen concentration in the 0-5 cm soil layer at the queried coordinate, sourced from SoilGrids, expressed in standard soil nitrogen units (cg/kg or equivalent). Only coordinates validated as falling within Slovenia's Natural Earth boundary are accepted; out-of-bounds coordinates are rejected before any charge is applied.
Example use cases
Agricultural field suitability assessment
“I'm evaluating a field near Maribor for crop planting — can you tell me the topsoil nitrogen level at latitude 46.55, longitude 15.65 so I know how nutrient-rich the soil is?”
Environmental baseline mapping
“For an environmental study in Slovenia, I need the SoilGrids total nitrogen reading at the 0-5 cm depth for the coordinate 45.82 latitude, 13.98 longitude.”
Precision farming data enrichment
“Can you pull the mean soil nitrogen content for the surface layer at lat 46.12, lon 14.85 in Slovenia? I want to add it to my farm management dataset.”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/si-soil-nitrogenWhen to prefer
Use this endpoint when you need topsoil (0-5 cm) total nitrogen data specifically for a coordinate within Slovenia and require automatic boundary validation to avoid wasted calls. It is ideal for agricultural analysis, soil health assessments, or geospatial enrichment pipelines scoped to Slovenia. Prefer this over general SoilGrids API access when you want a pay-per-call micropayment model with built-in geographic guardrails.
Side effects
- Coordinate outside Slovenia boundary: request rejected before payment with a boundary validation error
- Coordinate outside overall European coverage range (lat 34–72.5, lon -31.5–40.5): rejected with validation error
- Missing or malformed latitude/longitude fields: returns a schema validation error
- SoilGrids upstream data unavailable: may return a service error or null value
