Sidewalk effects on soil moisture and temperature beneath center and edge of sidewalks and under sod 18 and 36 inches from edge, Davis, California. Moisture data in percent (bold) are from August 26, 1982. Moisture values based on the full data set used in analyses are shown without parentheses. (Values in parentheses result from excluding erratic readings that may have resulted from compaction or other soil irregularities or from instrumentation problems and probably indicate the most usual moisture patterns.) Temperatures in °F (morning/midday/evening) are from September 2, 1982.
