How this service works
Mean SoilGrids cation exchange capacity for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Finland; results outside it are rejected before payment.
Output
A numeric value representing the mean cation exchange capacity (CEC) of the 0-5 cm topsoil layer at the queried coordinate, derived from SoilGrids data, expressed in cmolc/kg. The coordinate is validated against Finland's boundary before payment is charged; coordinates outside Finland are rejected.
Example use cases
Agricultural soil fertility assessment
“I'm evaluating farmland near Tampere, Finland — can you look up the cation exchange capacity of the topsoil at latitude 61.4978, longitude 23.7610? I need to understand the nutrient retention potential of this site.”
Environmental impact site screening
“We're doing a pre-construction soil assessment at coordinates 65.0121, 25.4651 in Finland. What's the mean SoilGrids CEC for the 0-5 cm layer there so we can flag any soil sensitivity concerns?”
Precision forestry soil mapping
“For a reforestation project in northern Finland at latitude 68.4, longitude 27.3, can you fetch the cation exchange capacity of the surface soil from SoilGrids so we can plan nutrient management?”
Technical details
Endpoint
POSThttps://nordland.halowerk.com/v1/fi-soil-cecWhen to prefer
Use this endpoint when you need a single, authoritative mean CEC value for a specific point location within Finland's borders at the 0-5 cm depth, sourced from the standardised SoilGrids dataset. Prefer it over generic soil APIs when Finnish boundary validation and SoilGrids data provenance are required, or when integrating with other HALOWERK Nordic Land sibling endpoints (pH, organic carbon, texture) for a multi-attribute soil profile.
Side effects
- Coordinate outside Finland boundary — request rejected before payment with a boundary validation error
- Latitude or longitude outside the declared European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Missing or malformed latitude/longitude — 400-level error
- Service unavailability or upstream SoilGrids data gap — 5xx error or null result
