Compost Ratio Mixer: Are Your Greens and Browns Balanced?
Compost piles fail mostly on ratio, not effort. This mixer checks your browns-to-greens balance before the pile goes wrong.
What is the Compost Ratio Mixer?
Compost works best with a balance of nitrogen-rich greens and carbon-rich browns. Enter the weights of each and this tool gives the browns-to-greens ratio and a plain reading on whether to add more browns or greens.

Worked example
Ten kilos of greens with 30 kilos of browns gives a 3 to 1 ratio, which reads as balanced.
What ratio is 10 kg of greens with 30 kg of browns?
Thirty divided by ten is 3, so the mix is 3 parts browns to 1 part greens, inside the balanced range.
