↵^zYear study period was for 2002, 2003, and 2004.
↵^yMODERATE = mean bulk density for three-year study of 1.64 g·cm⁻³, HIGH = mean bulk density for the three-year study of 1.77 g·cm⁻³; sample sizes for each year or compaction treatment are indicated in parenthesis; means ± mean standard error followed by different letters indicate a significant differences between mean daily transpiration per leaf area rate between years or soil treatments averaged across the three-year study period at P ≤ 0.05.
