The software developed allows the users to exchange, integrate, and analyze data in new ways. Users can combine various environmental indicators (organic carbon content) and information accessed ...
متن کاملSoil warming, carbon-nitrogen interactions, and forest carbon budgets.
Soil warming has the potential to alter both soil and plant processes that affect carbon storage in forest ecosystems. We have quantified these effects in a large, long-term (7-y) soil-warming study in a deciduous forest in New England. Soil warming has resulted in carbon losses from the soil and stimulated carbon gains in the woody tissue of trees. The warming-enhanced decay of soil organic ma...
متن کاملThe Effect of Paved Roads on Organic Carbon Content of Soil in Taham Dam Basin
Background; Contamination of water and soil through non-point sources such as road runoff causes environmental concern. The aim of this study is to determine the effect of Zanjan – Chavarzagh road on the total organic carbon (TOC) content of sediments in tributaries and the river that lead to Taham Lake. Methods; In tributaries and the river 69 soil and sediment samples were taken and the Tota...
متن کاملEnhanced decomposition of stable soil organic carbon and microbial catabolic potentials by long-term field warming.
Quantifying soil organic carbon (SOC) decomposition under warming is critical to predict carbon-climate feedbacks. According to the substrate regulating principle, SOC decomposition would decrease as labile SOC declines under field warming, but observations of SOC decomposition under warming do not always support this prediction. This discrepancy could result from varying changes in SOC compone...
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 ...
