Soil Amendment with Flyash through Vermicomposting by the Action of Epigeic Earthworm

Abstract

The coal based industries are key sources of huge production of Fly Ash (FA). According to the current scenario about 87% of FA are utilized globally but the continuous production and over production is still constant. An effective recycling is the major solution for sustainable utilization of FA. It has ability to increase the soil nutrition due to contain oxides of heavy metals for the purpose of agricultural practice. A subsequent quantity is required for soil amendment by adding various proportion of FA. Vermicomposting (VC) is a dynamic involvement of microbes with vermis or worms especially earthworms to convert the waste into organic manure in form of vermicasts. The present study was experimented out by taking various proportions of FA such as 20%, 40%, 60%, 80% and 100% including soil+ cow dung (Organic Manure-OM) as control. Each of proportions adding with the rest amount of OM to make it 1kg for the purpose of amendment. All proportions were under the process of vermicomposting by the action of Eudriluseugeniae after it’s inoculation.  This paper was focused on to find out the suitable proportion of FA can be able to the amendment for crop yielding by estimating through different physico-chemical parameters that obtained during vermicomposting.
