ind_gw_target

This function modifiers the groundwater recharge indicator with a correction
factor based on the soiltype and groundwaterclass. Wetter groundwaterclasses
give higher values, peat gives higher values than clay, and clay higher than sand.

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.
By providing results of a soil analysis and management info the 'OBIC' package can be use to calculate he scores, indicators and derivatives that are used by the OBI.
More information about the Open Bodem Index can be found at <https://openbodemindex.nl/>.
