The Open Bodem Index (OBI) is a method to evaluate the quality of soils of agricultural fields in The Netherlands and the sustainability of the current agricultural practices.
The OBI score is based on four main criteria: chemical, physical, biological and management, which consist of more than 21 indicators.
