*Recarbonizing global soils - A technical manual of recommended management practices* FAO, 2021 the existing data on the impacts of the main soil management practices on SOC content in a wide array of environments, including the advantages, drawbacks, and constraints.
Volume 1: - Introduction and methodology http://www.fao.org/3/cb6386en/cb6386en.pdf
Volume 2: - Hot spots and bright spots of soil organic carbon http://www.fao.org/3/cb6378en/cb6378en.pdf hot spots of SOC as areas that represent a proportionally little of the global land surface but on which SOC storage is highly effective; bright spots as large land areas with low SOC stocks per km2 that represent a potential for further carbon sequestration.
