Irrigation is the largest global water consumer, highlighting the need for efficient systems to optimize water use and crop performance. Irrigation quality is measured by application efficiency and distribution uniformity, influenced by factors such as technology, design, management, and meteorological conditions like wind. This study evaluates sprinkler irrigation uniformity in a 0.49 ha experimental plot using pluviometers, soil water sensors, and drone imagery. Three sprinkler configurations were tested (4CC, 2SS, 3SS), with 4CC showing the best uniformity and 3SS the worst. Wind significantly affected water distribution and evaporation. Drone imagery provided better rainfall estimation than local sensors, with thermal and visible spectrum análisis showing strong correlations. However, predictive models for rainfall failed in comercial plots, indicating the need for plot-specific models. This research enhances understanding of irrigation uniformity and proposes low-cost methods for monitoring using drones and a few pluviometers.
