Title: Soil carbon dioxide partial pressure and dissolved inorganic carbonate chemistry under elevated carbon dioxide and ozone

Author: Karberg, N.J.; Pregitzer, K.S.; King, J.S.; Friend, A.L.; Wood, J.R.;

Date: 2005

Source: Oecologia. 142: 296-306.

Publication Series: Scientific Journal (JRNL)

Description:

Global emissions of atmospheric CO2 and tropospheric O3 are rising and expected to impact large areas of the Earth’s forests. While CO2 stimulates net primary production, O3 reduces photosynthesis, altering plant C allocation and reducing ecosystem C storage. The effects of multiple air pollutants can alter belowground C allocation, leading to changes in the partial pressure of CO2 (pCO2) in the soil, chemistry of dissolved inorganic carbonate (DIC) and the rate of mineral weathering.

Keywords: Carbon-13, carbon sequestration, FACE, free air carbon dioxide and ozone enrichment, global, carbonate/silicate weathering cycle
