Composting is most efficient with a carbon-to-nitrogen ratio of about 25:1. [10] Hot composting focuses on retaining heat to increase the decomposition rate, thus producing compost more quickly. Rapid composting is favored by having a carbon-to-nitrogen ratio of about 30 carbon units or less. Above 30, the substrate is nitrogen starved.

Cattle manure is a good source of nitrogen as well as organic carbon. [3]
