Model for Estimating Soil Chemical Properties with RGB Drone Images

Abstract

 La agricultura de precisión optimiza la gestión de cultivos al proporcionar datos precisos sobre las propiedades químicas del suelo, mejorando así la productividad y sostenibilidad agrícola. Este estudio tiene como objetivo desarrollar modelos para estimar propiedades químicas del suelo, como pH, conductividad eléctrica (CE) y materia orgánica (MO), mediante el análisis de imágenes RGB capturadas por dron. La metodología incluyó vuelos fotogramétricos con un dron DJI Phantom 4 Pro equipado con una cámara de 20 Mpx y la toma simultánea de muestras de análisis de laboratorio y mediciones in situ, con sensores multiparámetros Royal Eijkelkamp EC meter set voor grond y pH meter set for soil and water. Las imágenes aéreas fueron procesadas con el software PIX4Dmapper, para generar la ortofoto y bandas espectrales. Con la ortofoto resultante de 1.6 cm/píxel, se calcularon ocho índices espectrales, usando las herramientas de análisis espacial del software ArcGIS. Los resultados in situ mostraron un valor promedio de pH de 5.83, indicando un suelo ligeramente ácido, y una CE de 1.09 dS/m, sugiriendo un suelo con baja concentración de sales disueltas. Los análisis de laboratorio evidenciaron un contenido medio-alto de MO, con un promedio de 5.19 %. Se encontró una correlación fuerte entre la MO y el pH_index con coeficientes de determinación R2=0.55, por su parte también se observaron correlaciones moderadas entre pH con el pH_index y CE con el sal_index6 con coeficientes de determinación R2=-0.39 y R2=0.42 respectivamente. Los resultados mencionados permitieron generar dos modelos para la estimación de estas variables a partir de imágenes RGB.
