Biochar and organic fertilizers are important alternatives to mineral fertilizers. Thus, it is important to understand how the co-application of biochar and organic fertilizers influences crop productivity and soil-plant phosphorus (P) trade-offs. Herein, we conducted a field fertilization experiment for eight years with maize-cabbage rotation. This experiment contained five treatments: no fertilization (CK), mineral fertilizers (CF), CF + biochar (BF), 20% substitution of mineral nitrogen (N) with organic fertilizers (OF), and OF + biochar (BO...
