The objective was to verify the performance of spectral techniques as well validation models in prediction nitrogen, total organic carbon, and humic fractions under different cultivation conditions. Chemical analyses for determination nitrate, chemical fractionation soil matter were performed, by Vis-NIR-SWIR X-ray fluorescence. results spectroscopy processed using RStudio v. 4.1.3, PLSR support vector machine learning algorithms applied validate models. XRF spectroscopic showed high are...
The need to maintain soil health and produce more food worldwide has increased, analysis is essential for its management. Although spectroscopy emerged as an important tool, it focus primarily on predictive modeling procedures rather than specific protocols. This article aims contribute a routine work sequence in hybrid laboratory that seeks provide the best data users. In this study, 18,730 samples from state of Paraná, Brazil, were analyzed using three different laboratories, sensors...
