The percentage of TN removed was
similar in treatments 3 and 4 (56% treatment 3 submerged, 58%
removal treatment 3 flood drain, 55% removal treatment 4) Pearson’s
correlation coefficient (r) was calculated to measure the effect
size of the condition (flood/drain or submerged). The effect size for
each of the measured forms of nitrogen was largest in treatment 3
and smallest in treatment 1.
