How this service works
Mean SoilGrids total nitrogen for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Netherlands; 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, derived from the SoilGrids dataset, for points validated to lie within the Netherlands boundary.
Example use cases
Farm soil fertility assessment
“I'm evaluating a farm plot near Wageningen — can you get the topsoil nitrogen reading for latitude 51.97, longitude 5.66 in the Netherlands so I can assess its fertility?”
Land valuation data enrichment
“I'm preparing a land appraisal report for a parcel in Groningen. Can you pull the SoilGrids total nitrogen value for the 0–5 cm layer at lat 53.22, lon 6.57?”
Precision agriculture site comparison
“I want to compare two potential field sites in the Netherlands — can you check the surface soil nitrogen at coordinates 52.08, 5.12 and 51.85, 4.63?”
Technical details
Endpoint
POSThttps://atlantikland.halowerk.com/v1/nl-soil-nitrogenWhen to prefer
Use this endpoint when you need point-level topsoil nitrogen data specifically for locations within the Netherlands, validated against official boundaries, and are comfortable with a pay-per-call micro-payment model. Prefer it over generic SoilGrids API access when you need boundary-enforced Netherlands-only queries with low per-call cost ($0.004 USDC). It is particularly suited for agricultural analysis, land valuation, and environmental monitoring workflows targeting Dutch land parcels.
Side effects
- Coordinate outside Netherlands boundary — request rejected before payment is charged
- Coordinate within European bounding box but outside Netherlands Natural Earth polygon — returns validation error
- Latitude or longitude out of the European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Missing or malformed latitude/longitude fields — input validation error
- SoilGrids data unavailable for the specific location — may return null or no-data response
