Article Synopsis
- Enhanced weathering (EW) of basalt, a silicate rock, is being studied as a method for carbon dioxide removal (CDR) to help mitigate climate change, particularly in tropical northeastern Australia.* -
- Field experiments from 2018 to 2022 measuring the effects of basalt on sugarcane crops showed increased soil pH and nutrient levels, but no significant improvement in crop yields or detectable increase in soil inorganic carbon levels.* -
- The study found that although the basalt weathering process did not significantly enhance CDR, it may still contribute to long-term reductions in CO emissions from the soil due to changes in soil acidity levels and delayed effects from continued basalt application.*
Field-based cavity ring-down spectrometry of δ¹³C in soil-respired CO₂.

June 2013
Measurement of soil-respired CO₂ at high temporal resolution and sample density is necessary to accurately identify sources and quantify effluxes of soil-respired CO₂. A portable sampling device for the analysis of δ(13)C values in the field is described herein. CO₂ accumulated in a soil chamber was batch sampled sequentially in four gas bags and analysed by Wavelength-Scanned Cavity Ring-down Spectrometry (WS-CRDS).
