Soil water potential values from 010 cb indicate a soil is nearly saturated, while a value of 1030 cb, depending on soil type, approximates field capacity (Figure 6). In the spring, values can change rapidly as both daily temperature and light levels increase, which causes larger increases in plant water use. Low-flow emitters are often used in vegetable gardens, with flow rates varying between 1 and 4 gallons per hour.
