ถ้A microcosm experiment with soil but without rice
plants was conducted in parallel (Figure 3a, b). Soil Eh in all
treatments rapidly decreased below -100 mV 4 days after
flooding (DAF) (Figure 3a). Although, no significant difference
in soil Eh among treatments was found, a more rapid
decrease in soil Eh occurred particularly during 1 to 4 DAF
in the RSH treatment than the BC and other RS treatments,
which Eh dropped at much slower rates. From 4 DAF and
until the end of experiment, soil Eh became more or less stable
in all of the treatments. However, soil Eh in BC treatments
was visibly lower than those in RS treatments.
Conversely, flood water pH measured in the corresponding submerged
soil (Figure 2b, 3b) displayed higher pH values in the order
of: BC treatments > RS treatments > control.
