Characterization and carbon storage of agroforestry systems in brazilian savannas of Minas Gerais, Brazil

Agroforestry systems (SAFs) as well as income generation and biodiversity conservation can be an alternative to carbon stocks. The study aimed to characterize and estimate the soil and plant carbon stocks of SAFs in Brazilian savannas of Minas Gerais State, Brazil. Three agroforestry systems and their adjacent native vegetation were evaluated. In addition, the forest inventory, the diameter distribution and vertical stratification of tree species were measured. The SAFs deployed from the management of native vegetation had a plant biodiversity and carbon stock in biomass, litter and soil similar to that of the adjacent area of native vegetation. On the other hand, carbon stocks in SAF deployed in the area cultivated with annual crops had lower species diversity and carbon stocks in biomass, litter and soil in relation to native vegetation adjacent. Agroforestry systems well managed have carbon stocks and biodiversity of natural resources like native vegetation.
