Article Synopsis
- Afforestation can help combat climate change by increasing carbon storage and providing ecosystem benefits, but soil nutrient availability can limit its success, particularly in nutrient-poor tropical regions.
- Enhanced rock weathering (ERW), specifically using wollastonite skarn, was tested in a rubber plantation in China to improve soil health and support biodiversity.
- The addition of wollastonite skarn showed significant improvements in various ecosystem functions but didn't affect soil enzyme activity; increased soil pH and microbial network complexity were key factors in enhancing ecosystem multifunctionality, suggesting ERW's potential for climate change mitigation.
Climate change is one of the most urgent environmental challenges that humanity faces. In addition to the reduction of greenhouse gas emissions, safe and robust carbon dioxide removal (CDR) technologies that capture atmospheric CO and ensure long-term sequestration are required. Among CDR technologies, enhanced silicate weathering (ESW) has been suggested as a promising option.

- Enhanced rock weathering (ERW) is a new method for removing carbon dioxide from the atmosphere and aims to improve soil carbon sequestration through geochemical processes.
- A 2-year study in tropical rubber plantations showed that adding wollastonite powder significantly increased soil organic carbon (SOC) more than soil inorganic carbon (HCO), with SOC increases being four to eight times greater.
- The study found that ERW enhances the accrual of stable organic carbon in soil by improving mineral-associated organic matter and boosting nutrient release, indicating that the impact on SOC should be considered when evaluating the effectiveness of ERW for carbon dioxide removal.
Enhanced weathering (EW) is an emerging carbon dioxide (CO2) removal technology that can contribute to climate change mitigation. This technology relies on accelerating the natural process of mineral weathering in soils by manipulating the abiotic variables that govern this process, in particular mineral grain size and exposure to acids dissolved in water. EW mainly aims at reducing atmospheric CO2 concentrations by enhancing inorganic carbon sequestration.

However, due to disparate study designs, it has been difficult to resolve whether a globally consistent set of predictors exists, or context-dependency prevails. Here, we used a network of 18 grassland sites (11 of those containing regional plant productivity gradients) to examine (i) if similar abiotic or biotic factors predict both large-scale (across sites) and regional-scale (within sites) patterns in bacterial and fungal community composition, and (ii) if microbial community composition differs consistently at two levels of regional plant productivity (low vs.
