My research focuses on long-term field trials linking soil health to crop productivity and sustainability. I have over two decades of experience managing long-term fertilization experiments across multiple climate zones in China, including studies spanning up to 30 years. My work investigates how NPK fertilizer programs and organic amendments affect soil organic carbon sequestration, nitrogen dynamics, and crop yield sustainability. I have quantified the relationships between soil fertility indicators and sustainable yield indices, providing evidence-based insights for balancing productivity with soil health. I am open to collaborations involving data sharing, joint analysis, and field trial coordination.
