American Residential Macrosystems - Soil chemistry data within residential yards in six major metropolitan areas, 2012-2013

"In six major U.S. metropolitan cities (Boston, Baltimore, Los Angeles, Miami, Minneapolis/St. Paul, and Phoenix), 1-meter soil cores were collected to evaluate soil microbial carbon and nitrogen cycle processes that are sensitive to land management. Laboratory methods followed those used by Raciti et al. (2011a,b) to measure microbial biomass carbon and nitrogen content, microbial respiration, potential net nitrogen mineralization, potential net nitrification, potential denitrification, and pools of extractable ammonium and nitrate.
