| 原文摘要 | Biochar and compost are of interest to agriculture. Particularly, when it comes to meet the goal of reducing mineral fertilisers and chemicals use. Biochar is created through pyrolysis from organic material at between 450 and 600 degree Celsius, in the absence of air. It can be based on plants and be used as a high carbon content soil improver. It can also be made of food grade animal bones, referred to as ABC (Animal Bone bioChar), and used as a high phosphorous content organic fertiliser. |
