Question

Why coir and husk waste are use for beding in vermicomposting?

Answer 1

Rapid growth of urbanization and industrialization has led to generation of large quantities of wastes. Major portion oforganic waste is dumped in landfill sites, creates the organic load on the ground water, and more emissions of landfillgases. The best possible alternative to reduce these potential pollutants is through vermicomposting. Vermicompostingis essentially composting with worms. This experiment was done to determine which bedding materials (eithernewspaper or sawdust) is more suitable for vermicomposting by using biological parameter which measured the growthrate (pH), number of worm, number of cocoons and worm biomass. The worms were breed in vermicomposter and theperiod of vermicomposting using Perionyx excavatus worm is six weeks. All of the four biological parameters showedthat there are significant different between this two type of bedding using ANOVA test. The Duncan test demonstratedthat newspaper bedding is more influential in worm biomass production and growth rate while sawdust bedding is betterfor cocoons production and number of worm. For pH analysis it reveals that the optimum pH for worm growth rate isnear to neutral condition. As conclusion, different types of bedding material will influence the worm growth.

Answer 2

Any material that provides the worms with a relatively stable habitat is called bedding. ... Worms need bedding in addition to food. Shredded paper or newspaper, coir (coconut husk fiber), and shredded cardboard are common bedding materials used for worm composting.
