Glob Change Biol 16:1366-1379 • Black carbon (BC) is produced in fires and is ubiquitous in the environment • BC degrades slowly in the environment, and is therefore important in the carbon cycle • To model black carbon in the carbon cycle, current stocks must be known • Here we estimate BC stocks in the United States Results BC in gradients at LTER sites Black Carbon Stocks in the United States BC in USGS stored samples BC content as a function of soil depth at the visited LTER sites Verena Jauss1, Johannes Lehmann1, Evelyn Krull2, Davit Solomon1, Bente Foereid1 1Crop and Soil Sciences, Cornell University, USA, 2CSIRO Land and Water, Australia • Conclusions • BC content in top-soil was highest in the Alaska LTER site, BC content decreased with soil depth at most sites • Black carbon content cannot be predicted from total carbon content • Adirondacks mountain range in the north-east of New York State showed higher BC contents than adjacent lowland areas Interpolated maps from Coweeta LTER site BC as a function of soil carbon at the Alaska LTER site Interpolated soil BC content for New York State based on interpolation of USGS samples
