Fig. 4From: In situ polymerization of soil organic matter by oxidative biomimetic catalysisSoil respiration (μg CO2 g−1 of soil), during 23 days of incubation, before and after the catalyst-assisted oxidative polymerization catalyzed by Fe-Pha (n = 3), and before and after fumigation with chloroform: control soil, soil + H2O2 + Fe-Pha, control fumigated soil, fumigated soil + H2O2 + Fe-Pha. Standard deviation was less than 5%Back to article page
