Compost Ratio Formula
The following formula is used to calculate the Compost Ratio.
COMPR = WC / WN
- Where COMPR is the Compost Ratio
- WV is the total weight of carbon (lbs)
- WN is the total weight of nitrogen (lbs)
The ideal ratio is roughly 30:1 carbon to nitrogen.
How to Calculate Compost Ratio?
The following example problems outline how to calculate Compost Ratio.
Example Problem #1:
- First, determine the total weight of carbon (lbs).
- The total weight of carbon (lbs) is given as: 500.
- Next, determine the total weight of nitrogen (lbs).
- The total weight of nitrogen (lbs) is provided as: 20.
- Finally, calculate the Compost Ratio using the equation above:
COMPR = WC / WN
The values given above are inserted into the equation below and the solution is calculated:
COMPR = 500 / 20 = 25:1
Example Problem #2:
For this problem, the variables required are provided below:
total weight of carbon (lbs) = 600
total weight of nitrogen (lbs) = 20
Test your knowledge using the equation and check your answer with the calculator above.
COMPR = WC / WN = ?
