Abstract:

This study aimed to investigate the carbon to nitrogen ratio (C/N) in vermicomposts produced from mixtures of cabbage, beans, and tea remnants combined with cardboard at a 1:1 ratio, totaling 2 kilograms, using two different types of worms: Lumbricus terrestris and Eisenia fetida. The results indicated that vermicompost produced by Eisenia fetida exhibited a significant decrease in C/N ratio by 18.60, whereas that produced by Lumbricus terrestris had a C/N ratio of 20.723. Regarding interactions, the highest initial C/N ratio among cabbage remnants, irrespective of worm type, was 25.000, whereas the lowest ratio after processing was 1.936 for tea remnants, showing significant differences. Across all remnants, there was a consistent decrease in C/N ratio post-processing, with cabbage remnants exhibiting the highest initial ratio of 25.00 before earthworm addition and tea remnants showing the lowest ratio of 8.530 after earthworm processing, indicating significant variation.
