How this service works
Mean SoilGrids pH in H2O for the 0-5 cm layer. The coordinate is validated against the Natural Earth boundary for Croatia; results outside it are rejected before payment.
Output
Returns the mean SoilGrids pH measured in H2O for the 0–5 cm soil depth layer at the queried coordinate. If the coordinate falls outside the validated Croatia boundary, the request is rejected before any charge is applied.
Example use cases
Crop suitability screening for Croatian farmland
“I'm evaluating a plot near Zagreb at latitude 45.85, longitude 16.05 — can you check what the topsoil pH is there so I know if it's suitable for growing wine grapes?”
Environmental baseline for construction site
“We're doing a site assessment near Osijek, Croatia, at lat 45.554, lon 18.695. Can you pull the surface soil pH for that location so we can include it in our environmental report?”
Precision agriculture soil mapping
“I need the soil pH at the 0-5 cm depth for coordinates 44.119 latitude, 15.231 longitude in Croatia — I'm building a soil acidity map for a client's agricultural holdings.”
Technical details
Endpoint
POSThttps://ostland.halowerk.com/v1/hr-soil-phWhen to prefer
Choose this endpoint when you specifically need topsoil (0-5 cm) pH in H2O for a location within Croatia, and want built-in boundary validation so out-of-country coordinates are rejected at no cost. It is well-suited for agricultural planning, land suitability assessments, or environmental baseline studies scoped to Croatian territory. If you need pH for other countries or deeper soil layers, look for sibling endpoints covering those regions or depths.
Side effects
- Coordinate outside Croatia boundary — rejected before payment with a validation error
- Coordinate within European coverage bounds but outside Croatia — boundary check fails
- Invalid latitude/longitude values outside the European coverage range — schema validation error
- Network timeout or upstream SoilGrids data unavailability
