Abstract:: Pot experiments were conducted to study the effects of biochar on mineral nitrogen transformations and nitrogen of rhizosphere of soybean. The results showed that nitrogen-fixing capacities were the highest at the podding stage, and then fell gradually. Ammonifying capacities were significantly different in flowering, bearing and podding periods and ammonifying capacities of 5% biochar treatment were much higher than those of CK. Nitrifying capacities of N₂Y₅ and N₁Y₅ treatments were significantly different from CK at seedling, flowering and podding stages and nitrifying capacities of N₂Y₅ were 58.87%, 84.49% higher than those of CK at bearing and maturing period, respectively. NH₄⁺-N contents of soybean rhizosphere were improved by use of biochar, and NH₄⁺-N contents of different treatments were significantly different at seedling stage, flowering and podding and bearing stages, but not remarkably different at maturing stage. Reasonable applications of biochar might play a key role in NO₃^--N utilization, and NO₃^--N contents of 5% biochar treatment were much higher than those of CK at seedling, flowering, podding and bearing stage. NO₃^--N contents of N₁Y₅, N₁Y₁₀ and N₂Y₁₀ treatments were 20.73%, 21.04% and 22.85% lower than those of CK at maturing stage.
