Plant and microbial N acquisition under elevated atmospheric CO 2 in two mesocosm experiments with annual grasses

  • Published 2005


The impact of elevated CO2 on terrestrial ecosystem C balance, both in sign or magnitude, is not clear because the resulting alterations in C input, plant nutrient demand and water use efficiency often have contrasting impacts on microbial decomposition processes. One major source of uncertainty stems from the impact of elevated CO2 on N availability to… (More)
