Balancing the carbon and nitrogen ratio is necessary for the composting process. The ratio of carbon (C) to nitrogen (N) – also called the C/N ratio – is very important for the biological degradation of organic waste. Both carbon and nitrogen are feedstock for the microorganisms that break down the organic matter: carbon is important for the cell proliferation, while nitrogen is the nutrient.
