Carbon Dynamics of Fruit and Vegetable Wastes and Biodegradable Municipal Waste Compost-Amended Oxisol

Recycling of wastes via composting is advocated as a means to reduce environmental hazards due the dumping wastes. Composting also creates vital source organic matter that important in nutrient and soil moisture retention, fertility preservation improving physical chemical properties soils. This study was conducted evaluate short-term effects four compost amendments an Oxisol on carbon dynamics (carbon dioxide evolution transformation). The composts were prepared 3:1 1:2 fruit vegetable waste (FVW) biodegradable municipal (BMW) with without indigenous microorganisms (IMO) (3:1 +IMO, −IMO, −IMO). Soil incubation studies carried out for 35 days at three application rates 0, 5 10 Mg ha−1, measurements done including CO2 evolution, dehydrogenase enzyme (DHA) assay Fourier transform infrared (FTIR) spectroscopy spectral analysis. At ha−1 rate, increased respiration rate obtained +IMO compost, mostly labile higher amount FVW mixture, which stimulated and/or their activities reflected by process decomposition added compost-amended DHA activity rates, significantly, highest recorded applied 1.38 triphenylformazan (TPF)/g dry soil/24 h. FTIR analysis showed transformations occurred out. A broadband between 3279–3347 cm wavelength indicated presence carboxylic hydroxyl functional groups because transformation composts.
