Primera parte: Almacenamiento insaturado de agua en un perfil de suelo

Abstract

Un fundamento para la correcta y eficiente aplicación y uso del recurso hídrico en los sistemas de producción agrícola es conocer el estado de humedad en que se encuentra el suelo ya que la cantidad a aplicar debe ser la misma que la cantidad consumida en el sistema suelo - planta por medio de la evapotranspiración. Este estado de humedad se debe de estimar lo mayor cercano posible a la realidad y para ello se debe de tomar el perfil del suelo a una profundidad a la cual se adapte lo mejor posible al o a los cultivos presentes. Normalmente la profundidad adecuada se refiere a la profundidad de raíces de las plantas y la forma de estimación se puede dar de varias maneras y una de ellas es por medio de la humedad volumétrica la cual, se puede estimar de manera directa como indirecta (como ejemplo podemos mencionar sensores calibrados). No obstante, con la información obtenida del campo se debe de realizar la estimación total respectiva que va a depender de la metodología utilizada respecto a la profundidad definida, el número de muestreos y la distancia entre los muestreos, los cuales; estos últimos se recomienda que sean de la misma longitud. Por ello el objetivo fundamental de este artículo es presentar diferentes opciones de manejo de la información obtenida de campo para estimar los contenidos hídricos insaturados en un perfil del suelo, compararlos en sus estimaciones para la toma de mejores decisiones.
