Brief description of research program
and goals: My assignment is that of Research Leader (August
1999), in the USDA-ARS National Soil Dynamics Laboratory
(NSDL), Auburn, Alabama. As Research Leader, I provide
leadership for the Unit and coordinate the Unit's research
programs. The mission of the NSDL is to develop technologies
and strategies for managing soils that increase adoption
of sustainable production/cropping systems, particularly
conservation systems reducing economic risks and farm
production costs; improve soil quality and productivity;
increase available water to plants and reduce risks from
short-term droughts; and relate agriculture to global
environmental change. NSDL contributes to the Agency's
global change initiative, which includes both agro-ecosystems
and natural ecosystems such as forests and rangelands.
My assignment is to reduce uncertainty regarding: (1)
the effects of rising atmospheric CO 2 concentration
on crop production and food security, and (2) the role
of agronomic ecosystems in the sequestration of atmospheric
CO 2 by soil. Specifically, my assignment encompasses
the determination of the effects of atmospheric CO 2
level on belowground processes which control crop productivity
and carbon/nutrient cycling, including structure and
function of root systems, soil microorganisms, soil carbon
dynamics, and CO 2 -induced soil responses. Both edaphic
and micrometeorological aspects of the entire crop system
are being studied. I plan and conduct in-depth research
to develop new knowledge relevant to this area of science.
