The study concludes, "Additional investments in soil organic carbon (SOC) research is needed to understand better the agricultural management practices that are most likely to sequester SOC or at least retain more net SOC stocks." [57] No-till farming reduces nitrous oxide (N 2 O) emissions by 40-70%, depending on rotation.
