The effect of different PGPR on N₂O emissions from agricultural soils

Description

Nitrous oxide (N2O) from agricultural soils is a potent greenhouse gas and a dominant ozone-depleting substance, underscoring an urgent need for sustainable mitigation strategies. Plant growth-promoting rhizobacteria (PGPR) represent a promising bio-based solution, given their dual role in enhancing plant productivity and regulating soil N cycles. This study explores the soil-specific mechanisms by which PGPR regulate N2O emissions, with research sites located in two contrasting soils in China: Wuxi, Jiangsu (paddy-upland rotation soil), and Dezhou, Shandong (upland-upland rotation soil).
