Carbon-to-Nitrogen Ratio - an overview ScienceDirect …
WebThe carbon-to-nitrogen ratio (C:N) of a material is an estimate of the relative amounts of these two elements it contains. The ratio is usually based on the percent dry weight of carbon and nitrogen in the material. A ratio of about 30:1 is ideal for the activity of the microbes in the compost. WebThe ideal C:N for composting is approximately 25-30:1. When piled to a point where heat can be trapped, this carbon-to-nitrogen ratio allows for thermophilic – or “heat loving” microbes to thrive, allowing your compost bin or pile to reach temperatures of 150°F or higher. This is often – though not always – achieved with equal ... brian church robinson bradshaw
