How this service works
Measures topsoil organic carbon for exactly two European coordinates with one method and reports the signed difference and winner where meaningful.
Output
Returns measured topsoil organic carbon values for both input European coordinates, the signed numerical difference between them, and an indication of which location has higher organic carbon content where the difference is meaningful.
Example use cases
Comparing two agricultural field sites
“I'm deciding which of two fields to prioritize for regenerative farming. Can you compare the topsoil organic carbon between Field A at latitude 51.2, longitude 8.9 in Germany and Field B at latitude 48.6, longitude 9.1? Tell me the difference and which is better.”
Vineyard site soil quality assessment
“I'm evaluating two potential vineyard sites in Spain — one at latitude 41.5, longitude -1.8 and another at latitude 40.9, longitude -2.3. Which one has more topsoil organic carbon and how big is the gap?”
Land valuation soil carbon check
“Before finalizing a land purchase, I need to compare topsoil organic carbon between the property I'm buying at latitude 47.3, longitude 15.6 in Austria and the neighboring parcel at latitude 47.31, longitude 15.62. Can you pull that comparison?”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/compare-two-soil-organic-carbonWhen to prefer
Use this endpoint when you need a direct, point-in-time comparison of topsoil organic carbon between exactly two European locations. It is purpose-built for pairwise land comparison with a single consistent measurement method, making results directly comparable. Prefer this over general soil data APIs when you specifically need the signed difference and a clear winner between two sites, and when both coordinates fall within European coverage bounds.
Side effects
- Coordinates outside the European coverage area (latitude 34–72.5, longitude -31.5–40.5) will result in an error
- Fewer or more than exactly two locations provided will be rejected
- Missing required latitude or longitude fields cause validation failure
- Locations with no available soil data in the underlying dataset may return null or incomplete values
- Network timeout or upstream data provider unavailability
