Kuzyakov, Y.; Horwath, W.; Dorodnikov, M.; Blagodatskaya, E. (2018): Review and synthesis of the effects of elevated atmospheric CO2 on soil processes. No changes in pools, but increased fluxes and accelerated cycles. In: Soil Biology and Biochemistry. DOI: 10.1016/j.soilbio.2018.10.005.

„We show that all effects in soil are indirect: they are mediated by plants through increased net primary production and C inputs by roots that foster intensive competition between plants and microorganisms for nutrients. Higher belowground C input from plants under eCO₂ is compensated by faster C turnover due to accelerated microbial growth, metabolism and respiration, higher enzymatic activities, and priming of soil C, N and P pools. We compare the effects of eCO₂ on pool size and associated fluxes in: soil C stocks vs. belowground C input, microbial biomass vs. CO₂ soil efflux vs. various microbial activities and functions, dissolved organic matter content vs. its production, nutrient stocks vs. fluxes etc.“
