Long-term application of high rates of nitrogen and phosphorus fertilizers and mono-tillage practices can adversely affect soil health, carbon sequestration and crop growth. A 10-year field experiment was conducted in a wheat-maize cropping system on China's Loess Plateau to explore fertilization and tillage methods that improve SOC sequestration and crop yields. We evaluated the effects of (1) fertilization (balanced fertilization (BF), low fertilization (LF), and conventional fertilization

BF and rotational tillage (NS, SP, and PN) increased the amount and stabilization rate of input-C. BF increased SOC storage compared to CF. Simultaneously, BF
