Chemical and enzymatic properties (n = 3) of the soil S1, S1A, S2, S2A, and S3 presented in mean (x̅) with the respective standard deviation (SD)_ Letters in brackets show significant differences between the soil samples (p < 0_05, one-way ANOVA and Bonferroni post-hoc test for pH, NH+4 content, and NO-3 content, and dehydrogenase activity; and Kruskal–Wallis one-way ANOVA with multiple comparisons of mean ranks and Bonferroni adjustment for DW, SOM, ammonification activity, and DMSO reduction)_Tabelle 1_ Chemische und enzymatische Parameter (n = 3) der Böden S1, S1A, S2, S2A und S3, als Mittelwert (x̅) mit Standardabweichung (SD) dargestellt_ Die Buchstaben in Klammern geben Informationen über signifikante Unterschiede zwischen den Böden (p < 0_05, One-way ANOVA mit Bonferroni post-hoc Tests für den pH-Wert, Ammonium- und Nitratgehalt und für die Dehydrogenaseaktivität und Kruskal-Wallis One-way ANOVA mit multiple Mittelwertvergleiche und Bonferroni Korrektur für das Trockengewicht, den Gehalt an organischer Substanz, für die Ammonifikation und DMSO- Reduktion)_
