What is it about?

This website provides a simple API for querying soil physical profile data in the Netherlands.

How are these soil profiles derived?

These soil profiles are the modal values for 368 soil mapping units derived by De Vries (1999). Note that these profiles are not actual field obervations, but merely derived from field observations. That's why they are called derived soil profiles. Each soil mapping unit has a derived soil profile which is assumed to be typical for that unit.

What soil properties are available?

The table below gives all soil properties that are currently available.

How does it work?

The API should be called by submitting a location as latitude and longitude (decimal degrees). We provide examples for several computer languages. Click on the language logos below to review examples of code snippets:

Bulk downloads are also possible. See for example this JavaScript code. You can even get soil physical profile data by directly typing a query in the address bar of your internet browser, e.g.:


Use cases

Terranimo® (Terramechanical model) is a computer model that predicts the risk of soil compaction by farm machinery. The Terranimo® model uses our API to query soil physical input data for the Dutch situation.
