Long-Term Effects of Different Fertilizer Management Practices on Soil Organic Carbon Pool in Smallholder Farms of the Huang– Huai–Hai Plains, China - Soil Management of Smallholder Agriculture - page 181

These data indicate that the increase in SOC concentrations and pools were strongly
influenced by different fertilizers and management treatments across the whole HHH.
The increase in the order of SOC was CFO > UFO > CF > O > UF > CK over a long-
term duration, and SOC in most of the fertilizer managements increased over time.
The results from eight long-term experiments at the field experimental level show that
the increase in chemical fertilizer inputs strongly enhanced the SOC pool across HHH.
