Protein bio-city as much as 50 ml/kg was used as a starter and it was added after having diluted and fermented for 48 hours. The compound was filled in the 10 I of plastic bucket and cured by lid on it. Every two days they were agitated and sprayed with water regarding to keep the humidity to be constant. The C/N ratio of the compos was analyzed chemically.
