Global climate change is an important problem in this time. It leads to a gradual increase in the average annual temperature of the planet, which began with the industrial revolution in the beginning of the 20th century. Extreme weather in recent years has made the talks about the growth of earth's temperature more intense. The change in temperature is explained by high levels of manufacturing and economic activity that includes emissions of main greenhouse gases: carbon dioxide, methane, etc. Carbon dioxide, a greenhouse gas, has the ability to trap heat in the atmosphere and contributes to global warming. Carbon sequestration is the process of capture and long-term storage of atmospheric carbon di oxide to mitigate global warming and to avoid dangerous impact of climate change. Soil carbon sequestration, the process of capturing and storing carbon in the soil, plays a crucial role in reducing atmospheric CO2. Process-based models such as the DeNitrification- DeComposition (DNDC) model have been increasingly used to understand the complex interactions between climate, crop and soil management through integration of the primary SOC turnover mechanisms. While carbon sequestration is important, the development of carbon-neutral technologies and alternatives to fossil fuels is also crucial. There is need for research, education, outreach and policy interventions to restore SOC pool, improve quality of soils of agro-ecosystems, increase productivity, and improve environment quality.
