Bioconversion of mango waste blended with poultry waste and cow dung into useful manure by aerobic composting

Solid waste can be disposed off either by diluting or by making it into useful manure. Since most of the land, water and atmosphere have been polluted largely, the only way to prevent pollution is to make the waste into a useful product. The present study investigates feasibility of blending the fruit waste (mango waste) with poultry waste and cow dung to produce a value added compost. Mango waste usually creates nuisance when compared to other fruit and vegetable waste as it gives foul smell. To achieve good composting mango waste was blended with poultry waste and cow dung at six different weight proportions. Chemical properties of compost like pH, nitrogen, carbon, phosphorus and potassium were observed at different periods, i.e., on the days 1, 21 and 35. Finally, the carbon to nitrogen ratio was compared with all the five samples to identify the best compost. The samples with ratio 1:1:1 and 2:1:1 without mango seeds were considered to be more reliable and efficient to be used as compost.
