Graphical overview of the three different experiments. The fertilization experiment is used as baseline, with calibration models from that dataset used to answer the three research questions. Note that box number 1 on the right is still part of the fertilization experiment, but specifically refers to the analysis and comparison of performance metrics. Box number 2 represents the experiment simulating herbarium storage conditions, while box number 3 represents the experiment involving herbarium storage duration. Furthermore, all four calibration models created from greenhouse data are used to answer research question 1, while for the other two only the calibration model for leaf nitrogen content of dry leaves is used for analyses
