Biogas byproducts affecting N2O, CO2 and CH4 production potential of Regosol soil under aerobic incubation.

Type: article
Abstract: Byproducts generation are increasing due to increase in biofuels demand. These byproducts are rich in variousplant nutrients. Digested slurry is left after biogas production. It can be converted into digested liquid and biochar.The laboratory incubation can provide an idea of their effects on greenhouse gases emission and environment.Considering this point, two concentrations of biochar and digested liquid were applied to Regosol soil andincubated under the aerobic conditions by keeping water holding capacity of the soil at 60 %. Digested liquidtreated soil produced the highest concentration of nitrous oxide due to the presence of higher ammonium nitrogenin digested liquid. Biochar treated soil produced the higher carbon dioxide than the untreated soils due to highcarbon content of biochar. The cumulative production of each gas showed that methane production was notsignificantly different among various soils and was also negligible in each soil due to the aerobic condition. Thecumulative production as well as the contribution towards global warming was the highest by carbon dioxideproduction in each soil, and it was followed by nitrous oxide production.
