Vermicompost was prepared by five different treatments from relatively resistant coconut husk mixed
with either pig slurry or poultry manure. The recovery of vermicompost varied from 35% to 43% and it
resulted in significant increase in pH, microbial biomass carbon, macro and micro nutrients concentration.
Among the treatments highest relative N (1.6) and K (1.3) recovery were observed for 20% feedstock
substitution by pig slurry while poultry manure substitution recorded highest P recovery (2.4). Compost
maturity parameters significantly differed and well correlated. The characteristics of different treatments
established the maturity indices as C/N 15–20; Cw < 1.8; Cw/Norg < 0.55; Lignin < 10–12; CHA/CFA > 1.5
and HI > 15.0. The manurial value of the coconut husk compost was improved by feedstock substitution
with pig slurry (80:20). The results revealed the technical feasibility of converting coconut husk into valuable
compost by feedstock substitution with pig slurry.
