Multispectral surveys are tools that have allowed for the acquisition of information about productive soils through overflights with unmanned aerial vehicles (UAV), that integrate a camera with the capacity to acquire images in very narrow ranges of different visible and non-visible light spectra. The research presented in this article focuses on identifying the behavior of variables such as vegetation cover density, crop phytosanitary status, and water footprint presence, among others, with the normalized difference vegetation index (NDVI) through the generation of an inspection and monitoring strategy that allows for rapid characterization of the studied soil and taking actions within agricultural activity. The strategy was implemented on a polyculture of beans, plantains, and cassava, on a particular property in the municipality of Candelaria Atlántico Colombia, conducting a multi-temporal analysis of multispectral surveys over a period of three months.
