Beijing, China – A recent field experiment reveals how applying biogas slurry as a topdressing can profoundly influence soil dissolved organic carbon (DOC), a critical component of soil health and carbon cycling, particularly in dryland agricultural settings. Published in Carbon Research, new findings from the Chinese Academy of Agricultural Sciences provide a comprehensive understanding of how this sustainable agricultural practice reshapes carbon transformation and stabilization across different maize growth stages and soil depths.

Biogas slurry, a nutrient-rich byproduct of anaerobic digestion, offers significant potential for sustainable agriculture by recycling organic waste and partially replacing chemical fertilizers. Despite its known benefits, the specific mechanisms by which biogas slurry topdressing (BSTD) regulates soil DOC dynamics under real-world field conditions, considering both crop growth and varied soil layers, remained largely unclear. Soil DOC is a highly mobile carbon fraction that fuels microbial activity and influences nutrient availability, making its precise management vital for robust agroecosystems.

A research team has shown that organic cleaning wastewater (OCW), a hazardous liquid waste produced during industrial chemical cleaning, can be co-processed with bituminous coal in pulverized coal-fired boilers, but only within a carefully controlled blending range.

A research team has developed a theory-driven and data-supported framework to predict how temperature controls the release of volatile organic compounds (VOCs) from automotive oil-based dry paint sludge, a hazardous waste produced during vehicle painting. 

A research team has developed OPTAR, a computational tool for discovering novel therapeutic targets from large-scale omics data. 

A research team has developed a multisite bridging-mediated lateral flow immunoassay (mbLFIA) that enables highly sensitive, portable detection of mosquito-borne viruses, using Chikungunya virus (CHIKV) as a model target.
