In Memory of James Petersen
Dr.
James Petersen was killed during an armed robbery while
doing research near Manaus, Brazil, on 13 Aug.
2005.
Dr.
Petersen was associate professor and chair of the Anthropology
Department at University of Vermont.
We will miss him as a
valued colleague and good friend.
ABSTRACT
Black Carbon (BC) may significantly affect nutrient retention and
play a key role in a wide range of biogeochemical processes in soils,
especially for nutrient cycling.
Anthrosols from the Brazilian Amazon
(ages between 600 and 8700 yr BP) with high contents of biomassderived BC had greater potential cation exchange capacity (CEC measured at pH 7) per unit organic C than adjacent soils with low BC
contents.
