| Abstract: |
| Reusing animal manure not only reduces environmental pollution caused by livestock and poultry industries, but also promotes agricultural sustainable development. Pyrolyzing manure has been proved to be an effective way to recycle animal waste. However, there is little information available about the effects of manure biochar on vegetable growth and soil fertility. A pot experiment was designed to examine soil fertility and cabbage growth following applications of swine manure biochar at 0.5%, 1% and 2% and swine manure at 1%, 2% and 4%, with chemical fertilizer as control. Compared with swine manure, biochar contained higher ash, organic carbon, total phosphorus, total potassium and available potassium, but lower total nitrogen, available nitrogen and available phosphorus. Soil organic matter, soil TN, available P and K increased significantly in both swine manure biochar and swine manure treatments, with higher values in swine manure than in its biochar, as compared with the control. Relative to the swine manure treatments, biochar applications increased the yield of Chinese cabbage by 26.50%~49.98%, N partial factor productivity by 119.32%~162.81%, leaf area by 20.84%~21.58%, soluble protein by 33.11%~42.93%, and vitamin C by 15.16%~46.06%, but decreased plant nitrate content by 17.80%~22.08%. Therefore, pyrolysis of manure may be a promising and effective way to reduce animal waste pollution and recycle waste. |
