About

Wenchao Cao is a leading researcher in agricultural soil science, with a focus on nitrous oxide (N₂O) emissions from intensively managed vegetable systems. Her work centers on understanding how manure application, irrigation, and straw incorporation drive greenhouse gas fluxes, particularly in China’s solar greenhouse fields—identified as N₂O emission hotspots. Her most-cited study (2019, 17 citations) reveals the mechanisms behind N₂O emission bursts following manure and irrigation, highlighting the significant environmental impact of these agricultural practices. Cao further explores how nitrogen and carbon inputs alter N₂O emissions from soil aggregates (2021, 11 citations), and her recent work (2025) demonstrates that straw incorporation can mitigate fertilizer-induced N₂O emissions in protected vegetable soils. She has also investigated the role of soil pH and carbon-to-nitrate ratios in denitrification pathways (2017), providing critical insights into the factors controlling N₂O production. Through her research, Cao advances sustainable soil management strategies, offering practical solutions to reduce greenhouse gas emissions while maintaining crop productivity in China’s vital vegetable-growing regions.
