Water Use for Drip-Irrigated Watermelon with Plastic Mulch in Florida

Figure 1. The drainage lysimeter for watermelon experiment Credit: Sanjay ShuklaWatermelon is an important crop in Florida and accounts for a significant part of its agricultural water use. Watermelon is grown in open fields and on raised plastic-mulched beds, with the latter being the predominant production system in Florida. Accurate water use estimates for this crop are needed to develop better water allocation and management plans as well as for irrigation management. This publication summarizes the results from a crop water-use study for the drip-irrigated watermelon in south Florida. This 3-page fact sheet was written by Sanjay Shukla, Niroj K. Shrestha, Thomas A. Obreza, and Brian J. Boman, and published by the UF Department of Agricultural and Biological Engineering, August 2014.

Using Multi-Sensor Soil Moisture Probes to Decide When and How Long to Run Drip Irrigation

Figure 1.  EasyAg multi-sensor probe with sensors (bottom) at 4, 8, and 12 inches. The PVC pipe (top) is the access tube (1.2 inch diameter) that houses the probe. The probe can be connected to a wireless datalogger and transmit the data to the farm office for its use or be made available on the Internet for it to be accessed by anyone.Several methods of irrigation scheduling are used by producers, including the feel method, calendar method, soil water balance method, and soil moisture measurement method. The latter two methods are superior and help avoid too much or too little irrigation, because they consider the water storage within the plant root zone. The soil moisture method commonly involves measuring soil moisture in the root zone and irrigating when the soil moisture falls below 33% or 50% depletion of available water capacity (water in soil that is available to the plant).

Interpreting Dye Test Results for Improved Drip Irrigation Management for the Mulched Vegetable-Production Systems in South Florida

Figure 4.  Wetting width along the bedWith Florida’s water withdrawals expected to increase by 30% from 2000 to 2030, South Florida vegetable producers are conserving water by converting traditional seepage irrigation systems to drip irrigation, which can have up to 90% efficiency when used effectively. Dye tests can provide important information for implementing a proper drip irrigation management program.
