Elemental compositions are shown in Table 1 for organic
amendments and in Table 2 for soil before and after the incubation.
Compost was characterized by a higher OC but a lower N content,
leading to much higher OC/N ratio compared to vermicompost
(Table 1). At the end of the experiment, OC content was significantly
higher in the soil amended with compost than with vermicompost
and the lowest values were recorded in the soil amended
with chemical fertilizers (Table 2). Interestingly, the utilization of
mineral fertilizers led to a significant decrease of OC and N
contents, and the utilization of vermicompost without earthworm
to significant decrease of N conten
