with the dry treatments. CEA values were greater in the ENP-TS cores in both the

benthic and 0 to -10 cm layers (Figures 5-1 & 5-2) and mimicked the CES relationships

between treatments with the exception of the WCA-3A cores in the 0 to -10 cm layer.

There was not a consistent trend with depth in either the CES or CEA values.

 The rate of increase of PER CES in the benthic layer was higher in the ENP-TS

cores. ENP-TS wet treatments exhibited greater CES values in both the benthic and 0 to

-10 cm layers (Table 5-4) which was also reflected in the CEA values (Figures 5-1 & 5-

2). PER CEA values mirrored the relationships between treatments in a similar fashion

to BGL, PHO, and PHE in the benthic layer. PER CES values decreased between the

benthic and -10 to -20 cm layers, reflecting decreases in the rate of PER production with

depth.

Nutrients

 Site core variability generally exceeded any differences between wet/dry

treatments as well as time effects. Therefore, the most consistent difference in nutrient

concentrations as well as lignin and cellulose occurred in comparisons between WCA-3A

and ENP-TS soil cores (Figure 5-3). Averages were calculated from a total of 15 cores

per layer-site combination from 0, 2, and 12 week incubations. Average cellulose content

ranged from 6.2 to 41% and was significantly greater in the WCA-3A cores, with an

inverse relationship in the -10 to -20 cm layer. Cellulose content increased dramatically

in the ENP-TS cores in the -10 to -20 cm layer, otherwise there was not a significant

relationship with increasing depth. Average lignin content ranged from 7.7 to 47.7%

with significantly higher concentrations found within the WCA-3A cores. Lignin content
