摘要

To slow down rising levels of atmospheric CO_2, the "4 per 1000" (4p1000) initiative was launched at the COP21 conference in Paris (http://4pl000.org). This initiative aims at a yearly 4%c (0.4%) increase in global agricultural soil organic carbon (SOC) stocks. If applied to all (also nonagricultural) soils, such a C sequestration rate could in theory fully compensate increases in atmospheric C02-C levels of 4300 Tg yr~(-1). We question the feasibility of the 4pl000 goal, using basic stoichiometric arguments. Soil organic matter (SOM) contains nitrogen (N) as well as C, and it is unclear what will be the origin of this N.
