How this service works
Mean SoilGrids organic carbon for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Estonia; results outside it are rejected before payment.
Output
Returns the mean SoilGrids organic carbon value (in g/kg or dg/kg) for the 0–5 cm soil depth at the queried coordinate, validated to fall within Estonia's boundary via Natural Earth polygons. Coordinates outside Estonia are rejected before the payment is processed.
Example use cases
Estonian farmland soil health assessment
“I'm evaluating a plot of farmland near Tartu — can you pull the topsoil organic carbon value for latitude 58.37, longitude 26.73 in Estonia so I can assess soil fertility?”
Carbon sequestration site screening
“We're looking for high-organic-carbon soils in Estonia for a carbon credit project. Can you check the 0–5 cm organic carbon at 59.43 latitude, 24.75 longitude?”
Environmental baseline data collection
“I need baseline soil data for an environmental impact study in northeastern Estonia — please get the mean organic carbon content for the topsoil layer at lat 59.15, lon 27.45.”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/ee-soil-organic-carbonWhen to prefer
Choose this endpoint when you need point-level soil organic carbon data specifically for locations within Estonia and want authoritative SoilGrids values with built-in boundary validation. It is preferable over generic global soil APIs when you need Estonia-specific data with boundary enforcement at minimal cost per call. Avoid if the coordinate may be outside Estonia — sibling endpoints cover other Baltic or European sub-regions.
Side effects
- Coordinate outside Estonia boundary — rejected with a validation error before payment
- Latitude or longitude outside the European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Point inside European range but outside Estonia polygon — boundary rejection
- Malformed or missing coordinate fields — request error
- Service unavailability or upstream SoilGrids data gap — server error
