Fig. 2. The effects of artificial flooding treatments on soil P availability as measured by daily P supply rate to in situ AER bags in field mesocosms. Brackets indicate periods of flooding. (A) CF = continuously flooded; (B) PF = periodically flooded; (C) MC = mesocosm control; (D) NC = nonmesocosm control; (E) FD = flooded–drained; and (F) +P and (G) +N, flooded–drained treatments with nutrients added. Lowercase letters indicate significant differences over time within a treatment (abc) (based on the method of least squares means with a Tukey adjustment [family error rate of P

(A) CF = continuously flooded; (B) PF = periodically flooded; (C) MC = mesocosm control; (D) NC = nonmesocosm control; (E) FD = flooded–drained; and (F) +P and (G) +N, flooded–drained treatments with nutrients added.

(A) CF = continuously flooded; (B) PF = periodically flooded; (C) MC = mesocosm control; (D) NC = nonmesocosm control; (E) FD = flooded–drained; and (F) +P and (G) +N, flooded–drained treatments with nutrients added.
