Enzymes activity changes during dairy manure composting.

Fulvic acid (A), humic acid (B), cellulase activity (C), urease activity (D), alkaline phosphatase (E) and dehydrogenase activities (F) were assayed during the dairy manure composting process. Ordinary two-way ANOVA with Tukey’s multiple comparisons test was used for statistical assessment. Values with different letters are significantly different at p < 0.05. FA, fulvic acid; HA, humic acid, CA, cellulase activity, UA, urease activity, ALP, alkaline phosphatase; DHA, dehydrogenase activities.
