• Optimizing split nitrogen application for enhanced maize yield in slightly saline coastal soils (ECe 3–4 dS m−1) (2026) · Discover Soil · doi

  The study identifies a gap in the current understanding of optimal N fertilizer application methods and timing for maize cultivation in coastal regions. The experiment addresses the need for effective N fertilizer application strategies in slightly saline coastal soils.

• Short planks in the crop nutrient barrel theory of China are changing: Evidence from 15 crops in 13 provinces (2022) · Food and Energy Security · cited 16× · doi

  Abstract Large quantities of fertilizers, mainly nitrogen (N), phosphorus (P), and potassium (K), are used in China's crop production; however, whether N, P, and K still limit yield under the current high input remains unknown.

• Elevated CO2 and warming intensify plant reliance on soil nitrogen reserves despite intensive fertilization (2026) · Nature Communications · doi

  The distinction between external nitrogen inputs and mobilization of soil nitrogen reserves remains poorly resolved. The role of soil nitrogen reserves in sustaining plant growth under climate change is not well understood.
