Abstract—Multispectral surveys enable information collection from fertile soils using unmanned aerial vehicles equipped with cameras capable of capturing images in specific narrow ranges of visible and non-visible light spectra. The research presented in this article focuses on identifying various variables such as plant health, chlorophyll levels, and the presence of desired nutrients. These variables are assessed using the Chlorophyll Index (CI) through the development of an inspection and monitoring strategy, which allows for the rapid characterization of the soil under study and facilitates decision-making in agricultural activities. The strategy was implemented on a specific property in Ponedera, Atlántico (Colombia), where a polyculture of beans, plantains, and cassava was cultivated. The study involved conducting multispectral surveys at multiple time points for three months.
