Grassland carbon storage
We found that, at each experimentally imposed level of plant diversity, the average annual rate of C storage in soils, as quantified by ΔC/Δt (units of Mg of C ha−1 y−1), was greater in the second period (13–22 years) of the experiment than in the first period (1–13 years; Fig. 1a, b). These accelerating rates of soil C … See more Root C and the amount of aboveground plant biomass produced each year (productivity) increased with plant diversity.
