Three irrigation scheduling methods (set schedule, ET-based, and tensiometer-based) were tested for papaya production in south Florida. ET-based irrigation scheduling was found to conserve water effectively. This 6-page document primarily focuses on the ET-based irrigation scheduling techniques for papaya under Florida conditions.

Minimum Number of Soil Moisture Sensors for Monitoring and Irrigation Purposes

Figure 4. Soil moisture distribution mapsManaging soil moisture properly through irrigation is key to increasing crop yield and conserving water. By understanding soil moisture variability, growers can better manage their irrigation systems to apply the right amount of water at the right time. This 4-page fact sheet proposes guidelines for soil moisture sampling that account for spatial variability, which helps to determine the minimum number of soil moisture sensors required to survey and monitor a specific area for irrigation.

Interpretacion del contenido de la humedad del suelo para determinar capacidad de campo y evitar riego excesivo en suelos arenosos utilizando sensores de humedad (AE496)

Figure 1.  RelaciĆ³n general entre el agua disponible para la planta (ADP), la capacidad de campo, el punto de marchitez permanente, el agua no disponible y la clase de textura del suelo.Este documento resume las directrices para la determinación de la capacidad de campo y la programación óptima del riego para suelos arenosos utilizando sensores de medición de la humedad del suelo (SHS). Los sensores de humedad del suelo han demostrado potencial para el monitoreo de la humedad del suelo, y para el respaldo en la toma de decisiones de riego en cultivos hortícolas.
