Table 4-4.


Soil layer nutrient, enzyme, and ratio parameters in P enriched and reference sites in LNWR and WCA-2A. Values
presented are means averaged over the three sampling periods with standard errors. Significant differences are given
between the enriched and background sites in the respective areas. Each asterisk reflects differences present at the p<0.05
level. Analysis was divided into the three sampling periods (1, 2, 3). Glucosidase, Leucine aminopeptidase, phosphatase
units are moles AMC or MUF released g-1 AFDM h-1. Phenol oxidase and peroxidase units are moles DICQ released
g-1 AFDM h-1. C:P= Total organic carbon to total phosphorus, C:N=Total organic carbon to total nitrogen, N:P=Total


 nitrogen to total phosphorus.
