Sažetak
Intensive agriculture has slowly degraded soils through pollution with pesticide residues, nutrients, and salinization, as well as crop residue removal, loss of soil organic carbon, and other threats. Therefore, a loss of soil fertility is observed. Soil analysis is an essential tool for precise management of fertilisation and irrigation, which enables to obtain high quality crops. Soil spectroscopy has proven to be a rapid, cost-effective, environmentally friendly, non-destructive, and analytical technique for determining soil properties. The main objective of this study was to propose an effective approach based on FTIR spectroscopy for determining soil properties of soil samples from different sites and management regimes. Spectral signatures in the mid-infrared range (4000-700 cm-1) were acquired using a spectrophotometer, and chemometric methods were used to correlate chemical and physical soil properties with their spectral signatures. Various calibration models can be used to quantitatively predict soil properties - such models were developed as a function of measured data from soil laboratory analyses and soil reflectance spectra. The FTIR spectra of the soil samples were subjected to multivariate analysis in the form of principal component analysis (PCA) and cluster analysis (CA). The multivariate analysis of the FTIR soil spectral data showed that it is possible to distinguish and classify soils at different sites based on their spectral signatures. These results demonstrate that FTIR spectroscopy and multivariate analysis can be used as a tool to identify and classify soil samples.
