“…A wheat‐maize rotation crop field in the North China Plain has been found to emit more CO 2 under conventional tillage (65 g CO 2 ‐C m −2 y −1 ) than with no tillage (39 g CO 2 ‐C m −2 y −1 ) (Wu et al., 2017). Similarly, deep tillage has been observed to increase total CO 2 emissions by between 4.9% and 37.7% in another wheat field in North China (Gong et al., 2022).…”

As the global population expands rapidly, there is a surge in global food demand. A 100%-110% increase in global crop demand from 2005 to 2050 has been predicted (Tilman et al., 2011). Using a more recent projection with 2010 as a baseline, the total global food demand is expected to increase by up to 56% in 2050 when considering climate change impacts (van Dijk et al., 2021). This drastic increase has exerted considerable pressures on agroecosystems (Kanianska et al., 2016). While agroecosystems play a critical role in global food supply, they also release greenhouse gases (GHGs) into the atmosphere contributing to climate change (Hartmann et al., 2013). Furthermore, global climate change, involving changes in precipitation and an increased frequency of extreme weather events that are likely to occur during this century (Canadell et al., 2021;Seneviratne et al., 2012), presents a significant challenge to agricultural production.

“…Indeed, while organic fertilizers may offer some benefits to reduce GHG emissions, their overall impact is influenced by various variables and requires careful consideration. In other cases, positive synergies can occur between climate-smart cultivation practices, such as reduced tillage and the use of organic fertilizers, with a significant reduction in GHG emissions as observed by Gong et al [154] and Zhang et al [155]. Finally, it is important to indicate that organic fertilizers, thanks to their origin (derived from waste products), make it possible to reduce the consumption of fossil and energy raw materials for the production of synthetic fertilizers (and, in many cases, emit fewer GHGs for the same amount of nutrients provided), and they also improve soil fertility, permitting better plant growth and leading to additional CO 2 organication and capture.…”

Agriculture is facing several challenges related to its sustainability. In this regard, the need to reduce its environmental impact related to the use of synthetic inputs and its potential role in mitigating global warming and climate change call for a review of crop management. In this context, and in the framework of achieving sustainable development goals, the use of organic fertilizers and bio-waste represents a valuable contribution to the agricultural transition towards a bioeconomy model by reducing the negative impacts of waste disposal. Farmyard manure, composts, digestate from agrifood processes, and biochar are, among organic fertilizers, commonly used to manage soils and support crop growth. These fertilizers can provide essential nutrients, improve structure, and enhance microbial activity, thus increasing soil fertility and agriculture sustainability. While organic fertilizers offer the benefits of soil fertility and plant nutrition, their impact on greenhouse gas (GHG) emissions is complex and varies depending on factors such as fertilizer type, soil conditions, and management practices. Although organic fertilizers may initially increase GHG emissions, they often lead to carbon sequestration in soils highlighting a negative C balance. Additionally, organic fertilizers promote a reduction in fossil fuel consumption used for synthetic fertilizer production, further contributing to GHG emissions’ reduction. Therefore, while organic fertilizers pose challenges in managing GHG emissions, their various benefits warrant careful consideration and strategic implementation in agricultural systems.

“…Different tillage practices and the soil's physical structure disruption can influence the soil environment and fertility [112]. Furthermore, alterations in soil temperature and moisture resulting from disturbances in the soil physical structure directly affect the GHG emissions from the soil by impacting microbial decomposition and root respiration processes [113].…”

Greenhouse gases (GHGs) like nitrous oxide (N2O), carbon dioxide (CO2), and methane (CH4) are both emitted and removed by soils. Accurate worldwide allocations of carbon budget are essential for land use planning, global climate change, and climate-related research. Precise measurements, drivers, and mitigation strategies are necessary, given agricultural soil’s significant potential storage and emission capacities. Different agricultural management practices cause greenhouse gas (GHG) emissions into the atmosphere and contribute to anthropogenic emissions. Agricultural soils can generate 70% of the world’s manmade N2O emissions and also behave as a CO2 sink and a source of organic carbon and as producers and consumers of CH4. When it comes to agronomic management, the source and sink of all these GHGs are distinct. Therefore, several approaches to measuring GHG emissions from agricultural soils are available and can be categorized into chamber systems and remote sensing approaches. Sustainable agriculture stands out as a viable and transformative approach to increase agricultural efficiency while addressing the challenge of GHG emissions. Incorporating advanced technologies, precise data analytics, and site-specific management practices can offer a pathway to mitigate GHG emissions, thereby reducing the global warming potential (GWP). Therefore, this review paper focuses solely on the drivers influencing and involving soil emissions and on quantification approaches for GHG emissions. In addition, mitigation practices aimed at optimizing GHG emissions from agricultural soils are highlighted.
