Synergistic effects of biochar and plants can reduce greenhouse gas emissions from salt affected soil.

ABSTRACT: Applying biochar and using cover crops are two potential approaches to reduce greenhouse gas (GHG) emissions. However, the effectiveness of these methods, individually or in combination, in salt-affected soils remains unclear. Thus, the objective was to determine the impact of barley (Hordeum vulgare) and biochar on N₂O and CO₂ emissions from salt-affected soil. During the 28-day replicated study, GHG emissions were measured near-continuously and the number of nirK, nirS, qnorB, and nosZ gene copies were measured 12 and 28 days after planting (DAP). Biochar accelerated barley emergence and reduced N₂O-N and CO₂-C emissions by 68% and 44% from 8 to 14 DAP, respectively. Barley reduced N₂O-N emissions by 30.4% between 8 and 14 DAP, and a
