Soil moisture status can be measured using neutron probes, time domain reflectometry, tensiometers, gravimetric methods, and electrical resistance blocks. Most methods have limitations; they may be time-consuming (gravimetric), expensive (neutron probe, time domain), or fixed in place (tensiometer, gypsum block, and neutron probe) (Schmugge, 1980; Weems, 1991). Water management in droughty, urban areas of the country would benefit from identification of a portable, fast, and relatively inexpensive soil moisture measuring device suitable for use in urban lawns and gardens. In this study, we have identified an instrument that may be suitable for this purpose.

indications that weeds are more problematic in strip-till compared with no-till and conventional-till systems ( Hoyt et al., 1994 ; Morse, 1999 ). It is also unclear whether erosion control and soil moisture retention will be as great in strip-till as no

grapes have been shown to have the highest periods of moisture demand in a double sigmoidal curve that parallels berry development ( Klein, 1983 ; Stevens and Harvey, 1996 ). Furthermore, soil moisture depletion under drip irrigation has been

BR areas may influence IR soil temperature, moisture, and IN dynamics in ST. These different growing conditions may result in improved crop growth and yield. For example, strip width influenced in-row soil temperature—with 15-cm wide strips, IR soil

capacitance soil moisture sensors require less maintenance and provide data that are easier to interpret than tensiometers, VWC may be the most useful measurement for automating irrigation systems ( Nemali et al., 2007 ). Capacitance sensors allow for easy
