ind_n_efficiency

This function gives an indicator value for nitrogen use efficiency calculated by <code>calc_n_efficiency</code>, this function makes use of <code>ind_nretention</code>

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/>.
