Abstract

Nitrous oxide and ammonia emissions from farmland need to be abated as they directly or indirectly affect climate warming and crop yield. We conducted a two-year field experiment to investigate the effect of biochar applied at two rates (no biochar application vs. biochar applied at 10 t ha⁻¹) on gaseous nitrogen (N) losses (N₂O emissions and NH₃ volatilization), plant N uptake, residual soil mineral N, and peanut (Arachis hypogaea L.) yield under three irrigation regimes: furrow irrigation (FI), drip irrigation (DI), and mulched drip irrigation (MDI). We found that MDI reduced residual (post-harvest) soil mineral N, cumulative N₂O emissions, and yield-scaled N₂O emissions as compared to FI. Biochar application increased residual soil NO₃⁻-N and decreased yield-scaled N₂O emissions as compared with the control without biochar application. Under the three irrigation regimes, biochar application decreased cumulative NH₃ volatilization and increased plant N uptake and yield compared with the control. Biochar application improved the sustainability of peanut production and could be used to alleviate the environmental damage associated with gaseous N emissions. Where possible, biochar application under MDI in peanut fields is recommended as a management strategy to minimize gaseous N losses.
