Forest and Pasture Carbon Pools and Soil Respiration in the Southern Appalachian Mountains
Our ability to estimate the changes in carbon (C) pools and fluxes due to forest conversion is hampered by a lack of comparative studies. We measured aboveand belowground C pools and soil respiration flux at four forested and four pasture sites in the southern Appalachian Mountains. Aboveand belowground C pools were significantly larger (P < 0.01, t-test) at forested sites relative to pasture s...
متن کاملSoil organic carbon dynamics jointly controlled by climate, carbon inputs, soil properties and soil carbon fractions.
Soil organic carbon (SOC) dynamics are regulated by the complex interplay of climatic, edaphic and biotic conditions. However, the interrelation of SOC and these drivers and their potential connection networks are rarely assessed quantitatively. Using observations of SOC dynamics with detailed soil properties from 90 field trials at 28 sites under different agroecosystems across the Australian ...
متن کاملResponse of soil labile organic carbon fractions to forest conversions in subtropical China
In order to determine the impact of forest conversions on labile organic carbon fractions, soils at depths of 0 10, 10 30 and 30 50 cm were collected from three types of forest: secondary monsoon evergreen broadleaved forest (BF), mixed pine and broadleaved forest (MF) and Masson pine forest (PF) in subtropical China. The light fraction organic carbon (LFOC), particulate organic carbon (POC) an...
متن کاملSummary Soil nitrogen can alter storage and remobilization of carbon and nitrogen in forest trees
of carbon and nitrogen in forest trees and affect growth responses to elevated carbon dioxide concentration ([CO2]). We investigated these effects in oak saplings (Quercus robur L.) exposed for two years to ambient or twice ambient [CO2] in combination with low(LN, 0.6 mmol N l) or high-nitrogen (HN, 6.1 mmol N l) fertilization. Autumn N retranslocation efficiency from senescing leaves was less...
متن کاملSoil Carbon Stocks Decrease following Conversion of Secondary Forests to Rubber (Hevea brasiliensis) Plantations
Forest-to-rubber plantation conversion is an important land-use change in the tropical region, for which the impacts on soil carbon stocks have hardly been studied. In montane mainland southeast Asia, monoculture rubber plantations cover 1.5 million ha and the conversion from secondary forests to rubber plantations is predicted to cause a fourfold expansion by 2050. Our study, conducted in sout...
