Recycling of Municipal organic waste

introduction

Vermiculture is the culture of earthworms. The earth worms can be used in the vermicomposting operation .Vermicomposting is the process by which worms are used to convert organic materials into a fertilizer known as vermicompost.Since compostingand vermicomposting are of the most promising low-cost technologies to convert municipal organic contaminant solid wastes into valuable organic fertilizer (Misra et al., 2003).There are many factors influencing the quality of produced compost, which include the pre-processing, particle size and feedstock utilized, the C/N ratio, bio-accelerator, nutrients, pH, aeration, moisture content, temperature, the maturation stage, etc (M.E. El- Haddad et al., 2014).vermicompost soil is rich in bacterial and fungal species which can degrade vast variety of organic waste into simpler soilnutrients(Bharat et al.,2015).The worms feed on organic materials, and fragment and digest them in their gut by their own enzymes and with the help of ingested micro-organisms, and excrete nutritionally rich feces or casts.The earthworm casts have been shown to contain increased quantities of important plant nutritional elements such as nitrogen, phosphorus and potassium together with the biologically active substances stimulating plant growth (Lee 1985).It is the same natural process that produces the dark humus layer on the forest floor. Modern composting differs only in the application of scientific knowledge and technology to promote morerapid decomposition and better control of the final product in an environmentally sensitive way.The present investigation is to study effect of vermicompost preparation from municipal organic waste and to observe its effect on plant growth and yield.
