Climate change has become one of the biggest challenges for farmers, advisors, researchers, and policymakers in recent years. Concerns about food security and the economic future have led these groups to search for methods to adapt to and mitigate climate change. In this context, cover crops have emerged as an important tool to improve soil health, prevent nitrate leaching, and increase crop productivity. The main objective of this review is to explore the multiple benefits of cover crops, including their role in improving soil health, sequestering CO2, fixing N2, and enhancing gas exchange, all of which contribute to the sustainability of agricultural systems under climate change conditions. One of the key findings of this research is that cover crop cultivation must be carefully tailored to the specific site, farm, intended purpose, and top priority, taking into account factors such as species selection, crop duration, and termination methods. Certain cover crop species have the potential to mitigate important climate change factors, such as soil erosion and nitrogen leaching, while increasing soil organic matter. However, many studies often focus on only one aspect of cover crops, overlooking the full range of ecosystem services they provide. In addition, future research must also address the economic challenges associated with cover crops.
