How this service works
Measures topsoil cation exchange capacity for exactly two European coordinates with one method and reports the signed difference and winner where meaningful.
Output
Returns topsoil cation exchange capacity values for both input European coordinates, the signed numerical difference between the two sites, and an indication of which site is the 'winner' (higher CEC) where meaningful.
Example use cases
Farmland acquisition soil quality check
“I'm evaluating two candidate farms in Europe — one in the Netherlands at 52.1°N, 4.9°E and another in Poland at 51.9°N, 21.0°E. Can you compare their topsoil cation exchange capacity and tell me which plot has better nutrient retention?”
Crop suitability comparison for two vineyards
“Compare the topsoil CEC at my two potential vineyard sites — one near Bordeaux at 44.8°N, -0.6°E and another in Tuscany at 43.5°N, 11.2°E — and tell me which soil holds nutrients better.”
Precision agriculture site benchmarking
“For my precision agriculture report, I need a topsoil cation exchange capacity comparison between our main field at 53.0°N, 9.0°E (named 'Hamburg Site') and a reference parcel at 52.5°N, 13.4°E (named 'Berlin Reference'). Which has the higher CEC and what's the difference?”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/compare-two-soil-cecWhen to prefer
Choose this endpoint when you need a direct pairwise topsoil CEC comparison for exactly two European sites using a consistent measurement method. It is ideal for land evaluation, agricultural site selection, or soil quality benchmarking within Europe. Use sibling endpoints for other soil metrics (pH, clay content) or for ranking more than two sites.
Side effects
- Coordinates outside the published European coverage bounds (lat 34–72.5, lon -31.5–40.5) result in an error
- Providing fewer or more than exactly two locations causes a validation error
- Invalid or non-numeric coordinate values are rejected
- Locations in non-European regions (e.g. North America, Asia) are out of scope
