Production of carbon occluded in phytolith is season-dependent in a bamboo forest in subtropical China.

Carbon (C) occluded in phytolith (PhytOC) is a stable form of C; when PhytOC is returned to the soil through litterfall it is stored in the soil which can be an effective way for long-term C sequestration. However, few estimates on the rate of PhytOC input to the soil are available. To better unders...

To better understand the seasonal dynamics of PhytOC production and the annual rate of stable C sequestration through PhytOC input, we quantified the monthly litterfall, phytolith and PhytOC return to the soil over a year in a typical Lei bamboo (Phyllostachys praecox) forest in subtropical China. The monthly litterfall ranged between 14.81 and 131.18 g m(-2), and the phytolith concentration in the monthly litterfall samples ranged between 47.21 and 101.68 g kg(-1) of litter mass, with the PhytOC concentration in the phytolith ranged between 29.4 and 44.9 g kg(-1) of phytolith, equivalent to 1.8-3.6 g kg(-1) of PhytOC in the litterfall (based on litterfall dry mass). The amount of phytolith input to the soil system was 292.21 ± 69.12 (mean ± SD) kg ha(-1) yr(-1), sequestering 41.45 ± 9.32 kg CO2-e ha(-1) yr(-1) of C in the studied Lei bamboo forest. This rate of C sequestration through the formation of PhytOC found in this study falls within the range of rates for other grass-type species reported in the literature. We conclude that return of C occluded in phytolith to the soil can be a substantial source of stable soil C and finding means to increase PhytOC storage in the soil should be able to play a significant role in mitigating the rapidly increasing atmospheric CO2 concentration.Zhang-Ting HuangPei-Kun JiangScott Xiaochuan ChangYan ZhangYu-Qi YingPublic Library of Science (PLoS)articleMedicineRScienceQENPLoS ONE, Vol 9, Iss 9, p e106843 (2014)
