Abstract
Composting and vermicomposting is a widely used method for disposal of organic wastes for nutrients recovery. Application of fresh organic wastes or non-stabilized compost to soil may leads to immobilization of plant nutrients and cause phytotoxicity. The environmental problems associated with raw coir waste (CW) application, such as release of polyphenols could be mitigated by stabilizing its nutrient and organic matter contents by composting/vermicomposting before application to agricultural soils. The objectives of this study was to evaluate the changes in nutrient content of CW amended with sugarcane bagasse (SBG) using different lignocellulolytic fungal inoculations and vermicomposting during over a period of 90 days in order to produce stabilized organic fertilizer. The composts and vermicompost were sampled at 0, 30, 60 and 90 days for the assessment of temporal changes in nutritional properties. Results revealed that nutrient contents during composting and vermicomposting showed a significant variation in all the treatments (p<0.05) for all the sampling days. Among the different treatments, vermicomposting and inoculation of fungal consortium, A. niger and T. viridae in CW and SBG mixed at equal proportion (1:1) produced a superior quality compost with desirable C:N ratio and higher nutritional status than natural composting. Therefore producing nutrient rich stabilized product from CW and SBG useful for sustaining high crop yield and minimizing soil depletion.
