Answer: Option B
Solution:
The C : N ratio of FYM is a ratio of the mass of carbon to the mass of nitrogen in a substance. The ratio of carbon and nitrogen in Farmyard Manure is 40 : 1.The carbon to nitrogen ratio is significant in composting because microorganisms need a good balance of carbon and nitrogen to remain active. A high C/N ratio can lead to prolonged composting duration and low C/N ratios enhance nitrogen loss.
