We found that species richness (S) increased over the first 20 years but decreased thereafter, and aboveground biomass showed a linear increase along the fallow time gradient..
The decomposition of H and M fractions with turnover times > 40 years contributes only 8% of the total annual respiration flux, with the remaining 33% (26%–43%) from root and
(2) after 20 years of differentiation, there was no significant dif- ference in C inputs to soil and SOC or SON stocks between continuous no-till and continuous full inversion
The objective of this study was to evaluate possible mechanisms of soil inorganic carbon formation in the Russian Chernozem fine-silty, mixed, frigid Pachic Hapludoll predominantly C3
The magnitude of this upper or ‘saturation’ limit will govern the ultimate significance of the soil sink and the time period over which it can be exploited for CO2 sequestration.. We
Soils exposed to elevated CO2 had higher relative abundances of fungi and higher activities of a soil carbon- degrading enzyme, which led to more rapid rates of soil organic matter

The measured variables are as follows: Photo - Photosynthesis rate, in mol CO2 m-2s-1 Cond - Stomatal Conductance, in mol m-2s-1 TLeaf oC -Leaf temperature, in oC ParIn_ m
