Description

A dataset of Near-Infrared (NIR) spectra collected in transflectance mode on aqueous fertigation solutions derived from a reclaimed wastewater. The ‘Wastewater_fertigation_2026.mat' is a MATLAB data file containing a DataSet object (DSO): ‘Wastewater_fertigation_2026’ including 1620 spectra collected in transflectance mode in the spectral range 1000–1800 nm (801 channels). Classes set on Row Labels in the DSO are: • Set 1: ID name of each sample • Set 2: Reference to outlet or inlet solution • Set 3: EC values (electrical conductivity, mS/cm) • Set 4: pH values • Set 5: Temperature values (°C) Info on how to open the DSO can be found at the following links: https://www.mathworks.com/matlabcentral/fileexchange/39336-dataset-object; http://www.eigenvector.com/software/dataset.htm.
