Vermicomposting of broiler farm waste.

摘要: The objective of the study was to know difference in growth two species earthworms as vermicomposting agents broiler farm waste. also proposed potency worms feed term nitrogen retention and metabolizable energy, moreover quality produced composts. This experimental done triplicate period eight weeks. There were earthworm used, namely: Lumbricus rubellus Eisenia fetida. weights measured every week, while nutritional values after 8 measurement worm’s weight. At end vermicomposting, carbon, nitrogen, phosphorus potassium contents compost analyzed. obtained data analyzed using t-test. results showed that both can be used agent energy are representing similar values, so could interchangeable use feed. Finally, result indicates provide no significant effect on C/N ratio, phosphorus, resulted vermicomposts. Since those organic matter above minimum requirement for National Standardization Indonesia, vermicomposts suitable single source fertilizer.
