Soil organic matter susceptible to climate change

Soil organic matter, long thought to be a semi-permanent storehouse for ancient carbon, may be much more vulnerable to climate change than previously thought. Scientists have found that the common root secretion, oxalic acid, can promote soil carbon loss by an unconventional mechanism -- freeing organic compounds from protective associations with minerals.
