How this service works
Measures topsoil nitrogen for exactly two European coordinates with one method and reports the signed difference and winner where meaningful.
Output
Returns topsoil nitrogen measurements for both input coordinates, the signed numeric difference between them, and a designation of which location has the higher nitrogen value (the 'winner') where meaningful.
Example use cases
Farm site selection by soil fertility
“I'm deciding between two fields for a new crop rotation project — one in northern Germany at 53.55 latitude, 9.99 longitude and one in central France at 46.60 latitude, 1.88 longitude. Which one has higher topsoil nitrogen and what's the difference?”
Comparing rewilding plots for ecological restoration
“We're evaluating two candidate rewilding areas — site A in southern Spain at 37.39 latitude, -5.99 longitude and site B in northern Italy at 45.46 latitude, 9.19 longitude. Can you check which one has better topsoil nitrogen levels?”
Due diligence on agricultural land purchase
“Before we finalize a land purchase, compare the topsoil nitrogen of the plot we're buying near Krakow at 50.06 latitude, 19.94 longitude against our existing field near Poznan at 52.41 latitude, 16.93 longitude — which wins and by how much?”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/compare-two-soil-nitrogenWhen to prefer
Use this endpoint when you need a direct, point-to-point topsoil nitrogen comparison for exactly two European locations. It is purpose-built for binary land comparisons with a signed difference and explicit winner — ideal for agricultural site selection, land due diligence, or ecological suitability assessments within Europe. Choose sibling endpoints for other soil metrics (CEC, texture, built-up share) or for ranking more than two sites.
Side effects
- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) return validation error
- Fewer or more than exactly two locations in the array returns a schema validation error
- Invalid or non-numeric coordinate values cause a 400-level error
- Coordinates in ocean or non-soil areas may return null or no-data responses
- Service unavailability may return 5xx errors
