Correct Answer - Option 1 : C, B, D, A

Carbon-Nitrogen ratio:

  • All organic matter is made up of substantial amounts of carbon (C) combined with lesser amounts of nitrogen (N).
  • The balance of these two elements in an organism is called the carbon-to-nitrogen ratio (C: N ratio). 
  • The fastest way to produce fertile, sweet-smelling compost is to maintain a C: N ratio somewhere around 25 to 30 parts carbon to 1 part nitrogen, or 25-30:1.
  • If the C: N ratio is too high (excess carbon), decomposition slows down.
  • If the C: N ratio is too low (excess nitrogen) you will end up with a stinky pile.
Waste material Carbon (C) to Nitrogen (N) ratio (C: N)
Food waste 18:1
Leaves and foliage 60:1
Paper 175:1
Cow manure 20:1

Therefore, the correct sequence of Carbon (C) to Nitrogen (N) ratio in decreasing order in organic waste material is C, B, D, A.
