Today, the growing world population and large scale urbanization
has created a global environmental issue for adopting a sustainable
approach in handling solid waste, with solutions such as
recycle of organic waste, to promote enduring agriculture as well as
a pollution-free environment. Vermicomposting is a nonthermophilic
process (Elvira et al., 1996), stabilizing organic matter
and converting important plant nutrients in the presence of
earthworms and microflora into a more soluble state to become
more available to plants (Atiyeh et al., 2002). Vermicompost is
considered an excellent product since it is homogenous with
desirable aesthetics, reduced level of contaminates; besides, containing
plant growth hormones and high level of soil enzymes, it
has a larger microbial population and tends to hold more nutrients
