Abstract:
In this paper, we performed a comparative analysis of the electrical impedance and optical methods performance for a field soil characterization. The study was optimized by reducing the texture variation and the influence of the unknown soil elements that are not in the focus of this research. The research dataset was created using pure soil from two agriculture farms and fertilized with fertilizers selected by farmers. The impedance spectrometer developed in our laboratory was used to perform the impedance measurements between 30 kHz and 14 MHz showing promising results. Optical measurements were performed within the ultraviolet-visible-near infrared (UV-VIS-NIR) range. The obtained results indicate that it is possible to perform low-cost soil analysis with high accuracy for a field fertilization analysis.
