Abstract

Annually,
too much green wastes are produced that they should manage for being useful.
One of their best using is composting. In this study the different green wastes
were collected from Urmia, West Azerbaijan- Iran and Anzali lagoon. These green
wastes were animal manure, hay debris, leaves of Maple and Platanus trees, the
remains of Azolla ferns, apple and grape pruning waste and Herbal Essences. Compost
formation was done in two processes including the inoculation of different
plant residues with fungi Trichoderma strains (T. ressei, T. viride
and T. harzianum and phanerochaete Chrysosporium and Chaetomium
globosum
) and followed by adding the Eisenia Fetida earthworms.
Results of formed vermicompost analysis showed that pH and C/N ratio decreased,
however the numbers of earthworm and cocoon significantly increased. At end of
study, the vermicompost of apple and grape pruning wastes was selected as the
favorite compost.
