The dispersion of rock dust in the soil is generally an effective way of storing carbon. But in acidic soils, according to an Australian study, this mechanism does not work<\/h2>\n

Rock dust boosts the soil’s ability to capture CO2<\/strong>, but the effectiveness of the operation is linked to some peculiar characteristics of the soil, starting with its acidity. This is highlighted by an experimental study<\/a> carried out in Australia and published in the journal Science of The Total Environment<\/em>.<\/p>\n

“Modelling studies suggest billions of tonnes<\/strong> of CO\u2082 might be removed annually if crushed rocks were applied to croplands globally,” writes<\/a> Paul Nelson<\/strong>, professor at James Cook University in Cairns, Queensland State, and co-author of the study on the Australian network portal The Conversation<\/em>. “But before everyone gets too carried away, it\u2019s crucial to be able to measure how much CO\u2082 is captured. Both industry and governments will need accurate measurements for effective policy, regulation and reporting”.<\/p>\n
