between enriched and reference sites in WCA-2A in the Everglades with values of

2520:63:1 and 360:9:1 in the enriched and reference sites, respectively, which were

correlated with higher C turnover rates (Koch and Reddy, 1992). Additionally, the

general increases in TP, TN, and TOC of both the benthic and soil layers at the enriched

habitats appears to support greater the higher Ecell/Ep and Ecell/En values.

 The supposition of greater productivity at the enriched habitats is also supported by

larger EICQ values, which are generally limited to the more active benthic layer. Greater

EICQ values in the benthic layer are synonymous with early stages of decomposition,

which have been shown to have a higher carbon quality (Sinsabaugh and Linkins, 1990;

Sinsabaugh and Moorhead, 1994; Sinsabaugh and Findlay, 1995). The positive

relationships between EICQ and productivity (r=0.80), microbial biomass (r=0.71) as

well as the negative relationship with POC turnover time (r=-0.99) (Sinsabaugh and

Findlay, 1995) therefore also suggest greater C mineralization at the enriched sites.

Additionally, this relationship between EICQ and microbial biomass is supported in the

Everglades by significantly higher microbial biomass C (MBC) and microbial biomass P

(MBP) observed within the benthic layer along a P gradient in WCA-2A (Wright and

Reddy, 2001b), greater soil respiration in higher P conditions (DeBusk, 1996), as well as

faster decomposition in a P dosing study in WCA-1A (Newman et al., 2001). High levels

of productivity (Sinsabaugh et al., 1997) have also been associated with more eutrophic

conditions. This relationship is dependent on a sufficient carbon flow that includes

saccharides and amino acids (Sinsabaugh et al., 1997). Increases of TOC, general

increases in primary production, and lower apparent N limitation on C mineralization at

the enriched habitats further supports these relationships. Therefore, the consequence of
