Influence of soil sample preparation on the quantification of NPK content through spectroscopy.
The dataset is comprised by four MS Excel files, two for the clayey soil and two for sandy soil used in the study, according the spectroscopy technique used (Diffuse Reflectance on Visible and Near Infrared region and Attenuated Total Reflectance on Mid Infrared region). Each file is divided in six tabs, according the soil preparation procedure used in the study (sieved mesch and dry temperature). Each tab contains the total N content and P and K availability measured by wet-chemical analysis, related to the full spectra.
