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.

• TRUE

• FALSE

Because of natural microorganisms, such as bacteria, actinomycetes, fungi and some protozoa, are already present in organic waste, the degradation phase starts directly after the piling.

• These aerobic microorganisms decompose or break down the carbohydrates and amino acids present in food and yard waste into simpler compounds, carbon dioxide and water

• These aerobic microorganisms decompose or break down the carbohydrates and amino acids present in food and yard waste into carbon dioxide.
