Glomalin, the substance coating this microscopic fungus growing on a corn root, can keep carbon in the soil from decomposing for up to 100 years.
Three new studies explore the potential roles of soils as a carbon sink in different regions in the Western Hemisphere. Scientists have investigated soil carbon balance in distinct agroecosystems ...
