Agroforestry systems have been considered as a sustainable land use, which are characterized by having layered vegetative canopies that mimic the native forest.It is known that woody species in agroforestry systems can improve soil physicochemical properties by supplying leaf or stem litter.However, little is known about the bacterial community structure and diversity in agroforestry systems.
