Highlights:
Fertilizer manufacture and use leads to around 15% of GHG emissions in agriculture.
Soil carbon (C) sequestration is an important strategy to reduce GHG emissions.
Fertiliser use promotes soil C sequestration by enhancing biomass C inputs.
Fertilizer input alters SOM elemental stoichiometry impacting decomposition.
In high fertility soils, fertilizer input accelerates the decomposition of SOM.
Abstract: Current initiatives to sequester carbon (C) in soils as a strategy to mitigate climate change are gaining momentum in many countries. While agriculture makes a significant contribution to greenhouse gas (GHG) emissions, it also plays a critical role in regulating global soil C pools, as almost 40% of the global soils are used for food and fibre production. Fertiliser manufacture and use in agriculture is a major contributor to GHG emissions. Agricultural management practices including tillage, pest and disease control, fertiliser input and irrigation impact soil C stocks and C sequestration potential, so improving agricultural soil management practices can help in mitigating climate change. This review provides a bibliometric analysis and critical discussion on the impacts of fertiliser use on soil C sequestration through increased C inputs resulting from greater biomass production, and formation of soil organic matter (SOM). Depending on the fertility status of the soil, fertiliser use can lead to either an increase or a decrease in soil C storage. In both low and high fertility soils, fertiliser use can promote soil C stocks by enhancing the amount of C inputs (e.g., crop residues) resulting from higher biomass yields, and improving stoichiometric relations of crop residues restored to the soil, thereby accelerating the rate of formation of SOM. In high fertility soils, fertiliser input can also accelerate the rate of decomposition of SOM, thereby impacting net C storage in the soil in relation to increased biomass yield. Fertiliser management practices, yields and soil conditions vary across regions, highlighting that recommendations on fertiliser use in relation to climate change mitigation strategies need to account for these differences.
