Gas entrapment and microbial N2O reduction reduce N2O emissions from a biochar-amended sandy clay loam soil
Nitrous oxide (N2O) is a potent greenhouse gas that is produced during microbial nitrogen transformation processes such as nitrification and denitrification. Soils represent the largest sources of N2O emissions with nitrogen fertilizer application being the main driver of rising atmospheric N2O concentrations. Soil biochar amendment has been proposed as a promising tool to mitigate N2O emission...
متن کاملN2o Emission from Miscanthus, Rye and Oilseed Rape
greater than CO2 (Callander et al., 1995). Therefore, the objective of the present work was to quantify the annual emission of N2O from winter rye, M. ‘Giganteus’ and winter oilseed rape. Furthermore the N2O emission will be related to the estimated net CO2-displacement. The annual emissions of N2O were measured using a closed-chamber technique and were based on results obtained by Jørgensen et...
متن کاملResponse of N2O emissions to biochar amendment in a cultivated sandy loam soil during freeze-thaw cycles
In the last decade, an increasing number of studies have reported that soil nitrous oxide (N2O) emissions can be reduced by adding biochar. However, the effect of biochar amendment on soil N2O emissions during freeze-thaw cycle (FTC) is still unknown. In this laboratory study, biochar (0%, 2% and 4%, w/w) was added into a cultivated sandy loam soil and then treated with 15 times of FTC (each FT...
متن کاملBiochar increases soil N2O emissions produced by nitrification-mediated pathways
*Correspondence: María L. Cayuela, CEBAS-CSIC, Campus Universitario de Espinardo, 30100 Murcia, Spain e-mail: [email protected] In spite of the numerous studies reporting a decrease in soil nitrous oxide (N2O) emissions after biochar amendment, there is still a lack of understanding of the processes involved. Hence the subject remains controversial, with a number of studies showing no cha...
متن کاملGaseous nitrogen emissions and forage nitrogen uptake on soils fertilized with raw and treated swine manure.
Treatments to reduce solids content in liquid manure have been developed, but little information is available on gaseous N emissions and plant N uptake after application of treated liquid swine manure (LSM). We measured crop yield, N uptake, and NH3 and N2O losses after the application of mineral fertilizer (NH4 NO3), raw LSM, and LSM that was decanted, filtered, anaerobically digested, or chem...
