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. After increasing, especially at higher plant diversity, … See more During succession in abandoned agricultural fields at our site, annual and short-lived perennial plant species were dominant initially19. … See more Soil C sequestration was positively associated with aboveground plant biomass and root biomass. A linear mixed model showed that soil C concentrations (as %) in the upper 20 cm of soil were positively correlated … See more Increases in biodiversity can impact ecosystem functioning because of sampling effects (the greater likelihood of the functionally best … See more WebApr 14, 2024 · In large-scale grassland ecosystems, there is great spatial heterogeneity in species composition and productivity due to variation in geography, climate, and other environmental conditions; consequently, the relationship between species diversity and productivity can vary.

WebN deposition can stimulate plant growth and soil carbon (C) input, enhancing soil C storage. Changes in microbial decomposition could also influence soil C storage, yet this influence has been difficult to discern, partly because of the variable effects of added N on the microbial enzymes involved.
