How this service works
Mean SoilGrids total nitrogen for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Denmark; results outside it are rejected before payment.
Output
Returns the mean SoilGrids total nitrogen value for the 0–5 cm soil layer at the specified coordinate. The value is derived from the SoilGrids dataset and represents nitrogen content for the surface soil horizon. Coordinates outside Denmark's Natural Earth boundary are rejected before processing.
Example use cases
Agricultural nutrient planning for Danish farm
“Can you look up the topsoil nitrogen level at latitude 56.12, longitude 10.21 in Denmark? I'm doing crop nutrient planning and need the SoilGrids mean nitrogen for the 0–5 cm layer at that field location.”
Environmental baseline for land survey
“I'm preparing an environmental baseline report for a site in Denmark at lat 55.40, lon 11.35 — can you get me the mean total nitrogen in the surface soil (0–5 cm) from SoilGrids?”
Soil health comparison across Danish sites
“I need to compare topsoil nitrogen at three Danish coordinates — start with latitude 57.05, longitude 9.92. Give me the SoilGrids mean nitrogen for the 0–5 cm layer there.”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/dk-soil-nitrogenWhen to prefer
Use this endpoint when you need point-level SoilGrids total nitrogen data specifically for a location within Denmark. It is ideal for precision agriculture, soil health assessments, environmental monitoring, and land-use planning workflows where nitrogen at the topsoil (0–5 cm) layer is required. Prefer this over generic SoilGrids API access when you want a lightweight, pay-per-call integration with built-in Danish boundary validation.
Side effects
- Coordinate outside Denmark's Natural Earth boundary — request rejected before payment is processed
- Latitude or longitude outside the European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
- Malformed or missing coordinate fields — schema validation error
- SoilGrids data unavailable for requested point — null or error response
- Network timeout or upstream SoilGrids service unavailability
