2007/3/23Values from the literature suggest that maximum emissions from piles would be 2.5 percent of the initial C and 1.5 percent of the initial N to volatilize as CH4 and N2O. If a pile contains 75 percent organic matter on a dry weight basis with a C:N ratio of 30:1, this would translate to about one ton of C evolving as methane for each 100 dry tons.
