Resumen de In dust we trust
Heffernan reflects on the vision laid out by researchers for enhanced weathering with fewer drawbacks, by using basalt on cropland in place of olivine, as it is less toxic and richer in phosphorus. She notes that if basalt were applied at a rate of 10 to 30 tonnes per hectare a year to two-thirds of the world's most productive cropland, it could capture 0.5 to 4 gigatonnes of carbon per year by 2100. Moreover, basalt could boost crop yields, cut fertiliser use, replace the soil additive limestone, and be spread with existing farm equipment
