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.雞糞生物炭土壤品質評估土壤肥力poultry-litter biocharsoil quality evaluationsoil fertility
