Soil Carbon Storage in Silvopasture and Related Land‐Use Systems in the Brazilian Cerrado

Silvopastoral management of fast‐growing tree plantations is becoming popular in the Brazilian Cerrado (savanna). To understand the influence of such systems on soil carbon (C) storage, we studied C content in three aggregate size classes in six land‐use systems (LUS) on Oxisols in Minas Gerais, Bra...

Description
Summary:Silvopastoral management of fast‐growing tree plantations is becoming popular in the Brazilian Cerrado (savanna). To understand the influence of such systems on soil carbon (C) storage, we studied C content in three aggregate size classes in six land‐use systems (LUS) on Oxisols in Minas Gerais, Brazil. The systems were a native forest, a treeless pasture, 24‐ and 4‐yr‐old eucalyptus (Eucalyptus sp.) plantations, and 15‐ and 4‐yr‐old silvopastures of fodder grass plus animals under eucalyptus. From each system, replicated soil samples were collected from four depths (0–10, 10–20, 20–50, and 50–100 cm), fractionated into 2000‐ to 250‐, 250‐ to 53‐, and
