T he nutrient cycle and organic matter decomposition are catalyzed by soil enzymes. In this study, enzymatic activities of catalase, dehydrogenase, alkaline phosphatase, urease studied in soils amended with compost (C), moss (M), or biochar (B) irrigated heavy metal-contaminated wastewater (HM-CW), when Nicotiana alata L. Petunia hybrida was grown pots. The irrigation HM-CW reduced the enzyme activities. However, combined used 5% M+C+B, results improved case N. P. hybrida, catalase activity 222.03 ± 9.24 402.34 10.48 mg KMnO4 g-1 h-1, respectively, which up to 94% higher than non-amended treatment. Similarly, M+C+B treatment also showed for dehydrogenase i.e., 180.24 6.95, 156.79 8.31 μg TPF h-1 that were 73% 49% Alkaline phosphatase production (μg p-nitrophenol h-1) 40.10 1.92 C+B 38.41 2.00, while 39.33 2.05, is significantly as compared Urease at application 83.22 5.54 urea much alata. general enhanced along amendments. It shows these amendments individually combination increased possibly through affecting dynamics.
