Soil nutrients is the material basis for plant growth and development, and play an important role in nutrient cycles and energy flow in terrestrial ecosystem. Global climate change caused by elevated atmospheric CO2 concentration ([CO2]) will affect plant nutrient uptake and soil nutrient concentrations supplied to the plant. However, soil nutrient responses to elevated [CO2] in different species planted in forest land is still poorly understood. This study use five economic and ecological woody species(Bet...
