Title: Impact of bio-fertilizers application on greenhouse gas emissions in rice paddy fields

Abstract:

Overusing chemical fertilizers has recently exacerbated farmland carbon loss and seriously harmed farmland ecosystems. As an alternative to inorganic chemical fertilizers, bio-fertilizers play a crucial role in enhancing soil's physical and chemical characteristics, organic matter content, and microbial communities. However, little is known about how bio-fertilizers affect greenhouse gas emissions from farmland ecosystems to the atmosphere. This project aims to assess how bio-fertilizers affect the major greenhouse gas fluxes of farmland ecosystems on a regional and global scale, and how long-term application of bio-fertilizers will affect greenhouse gas emissions in the future. This knowledge will be key to mitigating the role food production plays in driving climatic warming.
