This ratio, often expressed as C/N, compares the mass of carbon-rich materials, or browns, to nitrogen-rich materials, or greens, within your pile. Balancing these two categories visually and by volume is the practical application of the science behind a healthy compost heap.

If the pile is compacted, slimy, and smells bad, it has too much nitrogen; fix this by adding bulky carbon materials like dry leaves or shredded cardboard and turning the pile to introduce oxygen. Problem Likely Cause Solution Slow decomposition Excess carbon, low nitrogen Add green materials like manure or food scraps Foul ammonia smell Excess nitrogen, lack of oxygen Add brown carbon materials and turn the pile frequently Pile is dry and not heating Insufficient nitrogen and moisture Add greens and water until it feels like a wrung-out sponge The Impact of Particle Size and Aeration.
Practical Strategies for Home Composting For the home composter, meticulously weighing every input is unnecessary and cumbersome. Carbon Sources (Browns): Dry leaves, shredded newspaper, cardboard, straw, sawdust, wood chips, and corn stalks.
Quickly Find the Ideal Carbon to Nitrogen Ratio for Your Compost Pile
Nitrogen-rich "greens" are usually moist and rich in proteins, acting as the primary fuel for microbial activity. Achieving the ideal balance ensures that microorganisms, the engines of decomposition, have the perfect fuel source and building blocks to transform organic waste into dark, crumbly humus efficiently.
