Table 3: Summary of whether the difference in soil volumetric water content (Diff-VWC) in the top 6 cm between inside and outside gas sampling base collars, separately among 10 and 15 weekly sample dates and among tillage [conventional tillage (CT) and no-tillage (NT)]-site position [up-(UP), middle- (Mid), and down- (Down) slope] treatment combination sin 2018 and 2019, respectively, differed from zero under furrow-irrigated rice production during 2018 and 2019 at the Rice Research and Extension Center near Stuttgart, AR. Bolded values were considered significant at the 0.05 level.
