Research progress on soil carbon storage in farmland

Soil organic matter plays a significant role in fertilizing soil, nourishing crops, regulating soil properties, and improving tillage properties. Therefore, research on the cycling, transformation, and balance mechanisms of carbon in soil has become a hot topic both domestically and internationally. Practice has shown that in order to fully utilize these effects, it is necessary to coordinate the accumulation and decomposition of soil organic matter, in order to not only increase the content of soil organic matter, ensure basic soil fertility, but also provide necessary nutrients to crops at an appropriate decomposition rate. Meanwhile, the impact of carbon cycling in soil on the atmospheric environment has received attention. How to increase soil carbon storage becomes the fundamental guarantee for unleashing the enormous role of soil organic matter and protecting the environment.
