Calculate the Carbon to Nitrogen ratio of your compost mix and get recommendations for the ideal 25–30:1 balance.
Ideal Range: A C:N ratio of 25:1 to 30:1 gives the fastest, odour-free composting. Below 20:1 causes ammonia smell; above 40:1 slows decomposition significantly.
Source: C:N ratios from USDA AMS National Organic Program & Cornell Waste Management Institute. Formula: Blended C:N = Σ(weight × C:N) ÷ Σ(weight).
