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.
