Prairie et al. (2023): Restoring particulate and mineral-associated organic carbon through regenerative agriculture

To better understand soil organic carbon (SOC ) formation and persistence, the authors separate it into two distinct forms, particulate organic carbon (POC) and mineral associated (MAOC). This study presents results from a global meta-analysis on the response of SOC, POC, and MAOC, to regenerative agricultural practices including no-till, cropping system intensification, and integrated crop–livestock (ICL). The authors found that regenerative practices increased both POC and MAOC, thus improving soil health and promoting long-term carbon storage.
