For decades, China’s vital agricultural soils have been growing more acidic, a trend that threatens crop productivity and ecosystem health. This acidification has been driven by the massive use of chemical nitrogen fertilizers and industrial emissions required to feed its population and powe...
Modern agriculture relies heavily on phosphorus (P) fertilizers to sustain high yields, but this dependency has led to widespread soil P accumulation and increased risks of water pollution. Reducing fertilizer inputs without compromising productivity remains a major challenge. Here, Prof. Wan...
Farming produces a huge amount of crop waste including straw, husks, and stalks every growing season. Unfortunately, common disposal methods—burning, plowing the waste back into the fields, using it as animal feed, and even composting—release greenhouse gases (GHG) such as methane (CH4), ni...
Wetlands are among the most efficient ecosystems for carbon (C) sequestration, storing more than 30% of global soil C in only 3–13% of Earth’s land surface. However, the spatiotemporal patterns of wetland C uptake and their role in regulating global land C sink dynamics have been poorly qua...
Cadmium (Cd) speciation dynamics during vascular transport in peanut plants remain poorly defined. This study combined 113Cd isotope tracing with multiple separation techniques and targeted mass spectrometry to characterize Cd speciation across four developmental stages. Cd was primarily sequ...
Quantitative analysis of regional-scale soil heavy metal (HM) sources presents significant challenges. The reliability of the widely used source apportionment model (positive matrix factorization, PMF) remains to be validated. Moreover, PMF are limited in their ability to dynamically assess s...
