摘要：養雞業產生大量之雞糞，由於對公共衛生影響的疑慮導致去化不易，因此需要有效的處理方法以解決雞糞衍生之環境和廢棄物處理之問題。本計畫將雞糞以不同條件炭化後，分析不同炭化產物之性質和元素組成，並以不同比例添加於農地和苗圃土壤中，在水稻、蔬菜和苗木生長所需的水分管理模式下進行孵育，分析孵育前後土壤理化性質，土壤肥力以及重金屬含量和有效性，以評估生物炭添加對土壤品質和肥力的影響。預期本研究之成果將有助於將雞糞再利用，達成再資源利用和廢棄物減量的雙重效果。同時，透過生物炭施用改善農地土壤品質、提高施肥效率，以降低作物生產成本。
Abstract: Poultry farmings in Taiwan produce large amounts of poultry litter. Due to the concerns of public health related to the direct use of poultry litter as fertilizer to soils, this renewable resource has been truned into a waste that requires proper management or disposal. In this project, poultry litters will be converted into biochars under different pyrolysis conditions and the chemical properties and elemental compositions of the products will be analyzed. Subsequently, the poultry litter biochars are amended to different farmland and nursery soils, which are then incubated under the water conditions of growing paddy rice, vegetables and tree seedlings. The soils before and after incubations will be analyzed for physical and chemical properties, soil fertility and heavy metal contents. The results will be used to evaluate the effects of poultry-litter biochar amendments on the quality and fertility of farmland and nursery soils as well as the contents and availabilities of heavy metals in the soils. Accordingly, the production of biochar from poultry litter are expected to be an effective method inrecycling and reuse the poultry litter and reducing the cost of waste
management. This approach may also provide benefits in improving soil quality and fertility for crop production and, consequently, reducing the cost of crop production.
