Scientists mixed just 3% volcanic ash into forest soil in a UC San Diego experiment; coleus plants grew roughly three times as much as plants in untreated soil

At UC San Diego, researchers have made an exciting discovery: adding volcanic ash to soil can significantly enhance plant growth. Their study revealed that incorporating just 3% basaltic ash not only boosts the biomass of coleus plants but also positively influences beneficial soil microbes. This finding showcases volcanic ash as a viable solution for rejuvenating poor agricultural soils, making it an effective tool for sustainable practices and carbon capture initiatives.
