Agricultural is a major contributor of GHGs, especially N2O. Mitigation of GHGs from agricultural systems is critical to halt global warming. Given the fundamental impact of the agricultural sector on California as well as the US economy and the complex factors, such as soils, crops and associated management activities, affecting GHG emissions, a comprehensive approach for mitigating agricultural emissions must be adopted. We looked at potential mitigation strategies from land use planning to fertilizer management practices in the field, and assessed their importance and feasibility in reducing GHG emissions from agricultural activities. Of particular importance is determining the factors and predicting N2O emissions from nitrification related and denitrification pathways. Though additional research on pathways affecting emissions is important, the involvement of producers, fertilizers manufacturers, consumers, and policy makers is needed to promote best management practices and achieve reductions of GHGs from agricultural, with minimum or positive impact on California's economy.
