Figure 3. Example of adequate irrigation management using soil moisture sensors for monitoring the volumetric soil moisture content in the upper soil layer (0-to-6-inch depth) on drip irrigation under plastic-mulched conditions for sandy soils. The black line indicates volumetric soil water content using soil moisture sensors. The gray line indicates irrigation events, each single daily irrigation event having a volume application of 943 gal/A (0.03 in). The dotted line indicates the soil field capacity line. Arrows indicate rainfall events.
