Compost C:N Ratio

Balance your compost pile's Carbon (Browns) to Nitrogen (Greens) ratio for optimal decomposition.

Browns (Carbon-Rich)

Amount (Bucket/Weight)

Greens (Nitrogen-Rich)

Pile Balance

Enter material amounts to calculate ratio

Overview

Composting bacteria need Carbon for energy and Nitrogen for protein. The ideal Carbon-to-Nitrogen (C:N) ratio is approximately 30:1.

💡

Pro Tips

Diverse materials help create better structure and aeration in the pile.
Shredding materials increases surface area and speeds up the process.
Turn your pile regularly to supply oxygen to the aerobic bacteria.

Fun Facts

"A pile that is too 'Green' (N-rich) will smell like ammonia and become slimy."
"A pile that is too 'Brown' (C-rich) will decompose very slowly and stay cold."
"Coffee grounds are actually 'Greens' despite their brown color!"

Formula: Ratio = (Total Weight) / (Weight_1/Ratio_1 + Weight_2/Ratio_2)
