Their functional diversity determines soil food web structure, which in turn affect nutrient availability of the soil. Theobjective of this research was to observe nematode functional diversity within decomposing plant litter of varied quality determined by its CN ratio. The experiments were conducted by combining plant litter of various CN ratio (7, 8, 24, 26, and 68), adding them with enriched forest soil, and setting them on the sand media (six treatments). Samples were taken from the sand media after 1, 2, 4, 6, 9, and 12 weeks incubation. Nematodes were identified at family level of taxon and assigned into functional groups, which then used to calculate food web indices. The results showed difference in number of nematode families, functional groups, abundance, and food web indices (Wilk’s lambda: 0.024). The indices indicated that substrate with medium CN ratio support fungal pathway (Channel Index reached 84), whereas that with low CN ratio support development of bacterial pathway (Enrichment index: 66-93). Structured food web was established only within non-enhanced treatment (Structure Index: 60-76).Overtime, channel index increased suggesting development of fungal pathway. In summary, plant litter quality determined soil food web development, in particular nematode functional diversity %B Internatiomal Symposium on Indonesian Biodiversity %I Faculty of Biology, Jenderal Soedirman University %C Purwokerto, Central Java, Indonesia %G eng
