Table 4-5. Soil nutrient, enzyme, and ratio parameters in P enriched and reference sites in WCA-3A and ENP-TS. 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 per sampling period. Analysis was divided into the three sampling periods (1, 2, 3). Glucosidase, Leucine
 aminopeptidase and Phosphatase units are moles AMC-MUF released g1 AFDM h-1. Phenol oxidase and Peroxidase
 units are moles DICQ released g-1 AFDM h-1.
