How this service works
Mean SoilGrids total nitrogen for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Croatia; results outside it are rejected before payment.
Output
A numeric value representing the mean SoilGrids total nitrogen for the 0-5 cm soil layer at the queried coordinate within Croatia, expressed in standard SoilGrids units (typically g/kg). Coordinates outside Croatian territory are rejected before processing.
Example use cases
Crop suitability assessment for Croatian farmland
“I'm evaluating a plot near Osijek, Croatia at roughly 45.55 latitude and 18.69 longitude — can you tell me the total nitrogen in the top 5 cm of soil there so I can decide if it needs fertilization?”
Environmental baseline for land acquisition
“Before we finalise purchasing land near Split, Croatia at coordinates 43.51 latitude, 16.44 longitude, can you pull the SoilGrids nitrogen reading for the 0-5 cm topsoil layer?”
Research data collection for soil quality mapping
“I need the mean soil nitrogen for the 0-5 cm depth at 46.00 latitude and 16.50 longitude in Croatia to add to our regional soil quality dataset.”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/hr-soil-nitrogenWhen to prefer
Use this endpoint when you need soil nitrogen data specifically for a point location within Croatia and want automatic boundary enforcement so out-of-country coordinates are rejected without incurring costs. Prefer this over general SoilGrids API calls when you need a pay-per-query micropayment model and Croatian-scoped validation built in.
Side effects
- Coordinate outside Croatia boundary — rejected before payment with a validation error
- Coordinate within European bounding box but outside Croatia — boundary check fails and request is refused
- Latitude or longitude outside allowed European range (lat 34–72.5, lon -31.5–40.5) — schema validation error
- Network timeout or upstream SoilGrids data unavailability — service error returned
- Malformed or missing coordinate values — schema validation error
