The effect of biochar on forage production and carbon sequestration
Every year, always some hay were damaged by unpredictable weather or bad preservation. Therefore, LRI developed a pyrolysis equipment to char the wasted hay. However, crop residue or many kinds of biomass wastes could be used as a source of biochar, also. There were many evidences showed that biochar application to soil could sequestrate carbon and produce agronomic benefit. Pangolagrass, napiergrass and forage corn are three major forages in Taiwan. It’s a common situation. The soil in perennial forage field was compacted by heavy machine-operation year over year. The soil in forage corn field was low in organic matter after continuous tillage. All of these conditions could affect domestic forage production. Therefore, this project wants to investigate the effect of biochar on domestic forage production and carbon sequestration. The purpose of this project is to create a low-carbon forage production system by biochar converted by field waste for both production improvement and carbon sequestration.

The application potential of biochar on poultry litter treatment
The production of poultry industry is important for domestic livestock industry. However, during to its high moisture and nutrient, poultry litter tended to attract flies and produce pungent order could be a problem for industry operation. Inappropriate management of poultry manure and house waste could result in water or soil contamination, poor bird performance and a loss of profits to the grower. Pyrolysis occurs in an oxygen-deprived environment, producing gases, liquids, heat, and biochar. Chemically, it has a higher carbon content; physically, it is has a much more porous surface area. It is also drier, lighter, and sterile—when poultry litter is converted to biochar, its mass is decreased. The unique characteristics of biochar make it promising to improve living environment of poultry and reduce green-house gas emission. The purpose of this project is using biochar to develop better strategies for poultry litter treatment and to improve poultry industry operation.
