The ideal Carbon to Nitrogen ratio (“browns” to “greens”) in a compost pile is somewhere between 25:1 and 30:1, depending on who you talk to and what you are planting. Some composters take the more laissez-faire approach, throwing in whatever they have when they have it, letting the C:N ratio be whatever it is going to be. Other composters strive for C:N perfection, researching the C:N ratio of certain materials and measuring the amounts of those materials that enter to pile to ensure the desired ratio.
Many of us do not have the time (or patience) to spend the time figuring out the perfect ratio for our pile, but still want to guarantee a great finished product. No need to fear, the “Compost Calculator” is here! This great resource allows you to enter how much of what type of material you have and then will tell you your C:N ratio! Easy as compost!
1 bucket of fresh cut grass + 1/4 of a bucket of fruit scraps + 2 buckets of dried leaves = 30:1 C:N ratio!
mix it up a little and add:
1/4 bucket coffee grounds + 1/2 bucket of food waste + 2 buckets of wood chips = 26:1 C:N ratio!
