Warming-related increases in soil CO2 e ux are explained by increased below-ground carbon flux
The universally observed exponential increase in soil-surface CO2 e ux (‘soil respiration’; FS) with increasing temperature has led to speculation that global warming will accelerate soilorganic-carbon (SOC) decomposition1, reduce SOC storage, and drive a positive feedback to future warming2. However, interpreting temperature–FS relationships, and so modelling terrestrial carbon balance in a wa...
متن کاملFertilization Increases Below-ground Carbon Sequestration of Loblolly Pine Plantations
The extent of fertilization of southern pine forests is increasing rapidly; industrial fertilization increased from 16,200 ha per year in 1988, to 344,250 ha in 1998. Fertilization increases stand productivity and can increase carbon (C) sequestration by: 1) increasing above-ground standing C; 2) increasing C stored in forest products; and 3) increasing below-ground C pools. This talk will conc...
متن کاملCanopy soil bacterial communities altered by severing host tree limbs
Trees of temperate rainforests host a large biomass of epiphytic plants, which are associated with soils formed in the forest canopy. Falling of epiphytic material results in the transfer of carbon and nutrients from the canopy to the forest floor. This study provides the first characterization of bacterial communities in canopy soils enabled by high-depth environmental sequencing of 16S rRNA g...
متن کاملUrban Tree Effects on Soil Organic Carbon
Urban trees sequester carbon into biomass and provide many ecosystem service benefits aboveground leading to worldwide tree planting schemes. Since soils hold ∼75% of ecosystem organic carbon, understanding the effect of urban trees on soil organic carbon (SOC) and soil properties that underpin belowground ecosystem services is vital. We use an observational study to investigate effects of thre...
متن کاملCanopy Tree–soil Interactions within Temperate Forests: Species Effects on Soil Carbon and Nitrogen
In a northwestern Connecticut forest, we quantified the carbon (C) and nitrogen (N) content of the forest floor and the top 15 cm of mineral soil and the rate of midsummer net N mineralization beneath six different tree species. There were large interspecific differences in forest floor depth and mass, in the size and distribution of C and N pools at varying soil depths, and in rates of midsumm...
