Biochar is increasingly promoted as a climate-smart amendment, yet its long-term effects on nutrient retention and greenhouse gas emissions in flooded rice systems remain poorly resolved. Here, we combine a 13 year field trial with graded straw biochar applications (0–22.5 t ha–1 season–1)...
To sustain food production under accelerating climate change, it is vital to understand how key nutrients respond to the combined effects of rising atmospheric CO₂ and warming. Unlike nitrogen, phosphorus (P) cannot be fixed from the atmosphere. Its availability is governed by finite rock ph...
Feeding the growing population is one of the greatest challenges and calls for increasing global crop yields. Rising atmospheric CO2 concentration under future climate conditions offers opportunities to increase yields via the CO2 fertilization effect on crops such as rice, which billions dep...
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...
