Assessment on variations in physico-chemical characteristics at different maturity phages of organic kitchen waste composting at Lucknow City U.P. (India)

Abstract

The present reserch papers deals with the evaluation of the changes happening at various stage in the decomposition of Organic kitchen waste, via the estimation of some important physico-chemical and heavy metals concentrations. Changes inside the composition characteristics of the compost over-time, included elevated electric conductivity, bulk density, water retaining capability and so forth, all through the decomposition system, wherein because the moisture content material were given reduced closer to the give up of composting. From the physico-chemical point of view, evaluation of compost’s moisture content material, pH, organic matter, calcium, magnesium, total phosphorus, sodium and potassium agreed with advocated requirements and higher heavy metals concentrations became detected at all the decomposition degrees of composting and were found to be inside the permissible limits of Ohai- EPA requirements. From the results, it may be concluded that, composting by using vessel method in aerobic condition ought to produce proper acceptable quality of compost, which may be used as organic manure or soil conditioner.
