| Sumario: | Soil and plants are pivotal to the processes important for maintaining the integrity of biogeochemical cycles, such as the carbon cycle. Over the past few decades, anthropogenic activities have disturbed the atmospheric carbon cycle, leading to severe CO2 emissions into the atmosphere. Soil carbon sequestration by plant root exudates is an important means for net removal of CO2 content from the atmosphere. The rhizosphere environment in natural ecosystems, such as forests and grasslands, can help to stabilize root exudates in soil, while conditions in croplands do not appear favorable to stabilize root exudates as a soil organic carbon (SOC) source. Thus, preserving forests and grasslands with plant species secreting a high amount of carbon compounds might increase the SOC content in the soil of these ecosystems. |
