FOR RAW RESIDUALS COMMONLY COMPOSTED IN THE STATE OF MAINE
The following table is provided for guidance and includes many of the raw residuals that, to date, have been composted within the State of Maine. In addition to carbon to nitrogen ratio (C:N) values, percent nitrogen (% N) has been included to better characterize eachresidual. As a general rule, the lower the C:N the higher the putresibility of the residual and the greater the chance of producing nuisance odors. All of the following information was obtained from:
Rynk, R, ed.1992. On-farm composting handbook. Northeast Regional Agricultural Engineering Service, Ithaca, New York. NRAES-54:106-113.
