"Description": "The Open Bodem Index (OBI) is a method to evaluate the\nquality of soils of agricultural fields in The Netherlands and\nthe sustainability of the current agricultural practices. The\nOBI score is based on four main criteria: chemical, physical,\nbiological and management, which consist of more than 21\nindicators. By providing results of a soil analysis and\nmanagement info the 'OBIC' package can be use to calculate he\nscores, indicators and derivatives that are used by the OBI.\nMore information about the Open Bodem Index can be found at\n.",
