Key Microbes Help Form Topsoil Crusts in Arid Lands

Caption

Temperature determines where key soil microbes can thrive -- microbes that are critical to forming topsoil crusts in arid lands. Arizona State University scientists predict that in as little as 50 years, global warming may push some of these microbes out of their present stronghold in colder US deserts, with unknown consequences to soil fertility and erosion.
