The comparison of physical and chemical characteristics of common compost and vermicompost

The main purpose of this research was to compare the physical and chemical characteristics of Common compost and Vermicompost (obtained from the same condition and organic matter).The worm species used in this research was Eisenia fetida. This research was carried out in green house for 5 months and it was performed in factorial RCD with 4 replicates. Experimental treatments consisted of 3 combination levels of organic matter as: 1- (A) 60% of cow manure and 40% of plant debris, 2-(B) 50% of cow manure and 50% of plant debris, 3-(C) 40% of cow manure and 60% of plant debris. And second factor was: 1-(W1) & 2-(W0) the treatment with or without any earthworm, respectively (earthworm treatment).The results demonstrated that the earthworm treatment effect on the whole measured characteristics (20 characteristics) except of Zn and EC amount has been significant (P  0.01). The vermicompost treatment which was measured 13 characteristics for it (65% of characteristics), was the first (class a). W1 in 15 measured characteristics (75%) and W0 by 25% characteristics were in the first and second class, respectively.Thus, the treatment of vermicompost consists of 60% cow manure and 40% of plant debris with Eisenia fetida has been known the best kind of compost.
