Carbon Nitrogen Ratio

Prepared by Muhammad Marrush - UC Davis International Programs The carbon-nitrogen ratio is a useful way to compare soil amendments. This ratio is an indicator of the stability of the soil supplement. Lower ratios mean the supplement is very stable and will not draw down nutrients from the soil that plants need to grow. In general, carbon-nitrogen ratios of 30 to 1 or lower are best.
