Does Volcanic Ash Fertilize The Globe?

Does Volcanic Ash Fertilize The Globe?

Hubert Staudigel

Scripps Institution of Oceanography at the University of California in San Diego

Volcanic soils are legendary for their fertility, and in particular volcanic ash is commonly considered as a potentially commercial use as a mineral fertilizer. The benefit of volcanic ash as a fertilizer appears obvious based on its nutrient contents but it is not clear whether, and under which circumstances this holds true. Staudigel will discuss the relationships between soil fertility and volcanic input into a soil through controlled greenhouse experiments that have shown that volcanic ash may result in a threefold increase in bioproductivity. This talk is based on a recent, freely downloadable paper published in the Journal Ecosphere (DOI: 10.1002/ecs2.70406) .
