Composting is considered as one of the oldest techniques developed in organic agriculture. However, traditional composting methodologies have many constrains from the ecological and economic point of view. One of the most important economic constrains is the production of methane gas which is one of the dangerous green-house gases responsible for the problem of climate changes. The other economic constrains is that it takes long time (3 to 6 months) for completing the operations. On the other hand, vermicompsoting is a fast technique for digestion of organic wastes and converting it into a valuable compost for the organic agriculture. In the present work, three composting materials were tested in our experiment for 90 days. The first one is Agricultural Crop Waste (W1), the second is poultry litter (W2) and the third is a mixture (V/V) of both of agricultural and poultry wastes (W3). It was found that the maximum produced vermicompost was in the third composting material. The outcomes propose that vermicompost can be presented as one of the innovations for organic agriculture applications.
