Variations in the relative isotopic abundance of C and N (delta13C and delta15N) were measured during the composting of different agricultural wastes using bench-scale bioreactors. Different mixtures of agricultural wastes (horse bedding manure + legume residues; dairy manure + jatropha mill cake; dairy manure + sugarcane residues; dairy manure alone) were used for aerobic- thermophilic composting. No significant differences were found between the delta13C values of the feedstock and the final compost, except for dairy manure + sugarcane residues (from initial ratio of -13.6 ± 0.2%° to final ratio of -14.4 ± 0.2%°). Delta15N values increased significantly in composts of horse bedding manure + legumes residues (from initial ratio of +5.9 ± 0.1%° to final ratio of +8.2 ± 0.5%°) and dairy manure + jatropha mill cake (from initial ratio of +9.5 ± 0.2%° to final ratio of +12.8 ± 0.7%°) and was related to the total N loss (mass balance). Delta13C can be used to differentiate composts from different feedstock (e.g. C3 or C4 sources). The quantitative relationship between N loss and delta15N variation should be determined. |
