• Basics of Evaporation and Evapotranspiration

      Brown, Paul (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2014-01)
      Introduction: Local information on evapotranspiration (ET) is now readily available from on-site weather stations and/or public weather networks to assist turfgrass professionals with irrigation management decisions. Proper utilization of ET information can provide accurate estimates of daily water use and thus can assist irrigation managers with the all important decisions of when to apply water and how much water to apply. The concept of ET can be confusing and often is presented in a highly technical manner. The objective of this and subsequent bulletins in the Turf Irrigation Management Series is to simplify the subject of ET and thereby increase the effective utilization of ET in irrigation management. This bulletin provides some basic background on the related subjects of evaporation and evapotranspiration.

    • Métodos para Medir la Humedad del Suelo para la Programación del Riego ¿Cuándo?

      Martin, Edward C.; Munoz, Carolina (College of Agriculture, University of Arizona (Tucson, AZ), 2017-02)
      El manejo apropiado del riego requiere la evaluación de parte del agricultor de sus necesidades de riego en base a medidas de varios parámetros físicos del suelo. Algunos productores utilizan equipo sofisticado mientras que otros se basan en métodos empíricos o en el sentido común. Cualquiera que sea el método usado, cada uno tiene sus propios méritos y limitaciones. El agricultor generalmente se hace dos preguntas al desarrollar una estrategia para el manejo del riego: “¿Cuándo regar?” y “¿Cuánta agua aplicar?”. Este boletín responde a la pregunta CUÁNDO.
