Fig. 2: Differences in reported (LOOP) and simulated (approach A) NB parameters.

The numbers in brackets represent the average of reported (NOVANA) and simulated (LDNDC model) values for each component, along with their ranges for the six LOOP catchments, in kg-N ha⁻¹ year⁻¹. TN In indicates the share of each component from the total N input.
