| Abstract: | Purpose Phyllostachys praecox is one of the bamboo species used for the production of fine edible bamboo shoots and is widely distributed in Southern China. To maintain or increase the productivity of bamboo shoots, P. praecox forests are intensively managed through heavy fertilization and surface mulch of organic residues such as rice husk to increase soil temperature in the winter. Such management techniques can markedly influence soil quality and the dynamics of soil carbon (C). The objectives of this study were to investigate the long-term impact of intensive management practices on carbon pools and forms in the soil of bamboo forests and explore relationships between different soil organic C fractions, as little such information is currently available. |
