Soil Site Productivity
Research Interests
My scientific interests are directed at quantifying how nutrient and hydrologic cycles control the chemistry of forest soils, drainage waters, and forest productivity. My research focuses on the management of the soil resource in an effort to maximize forest growth and to maintain ecosystem quality. At the stand level this includes questions of fertilizer use efficiency, soil nutrient supplies, and long-term soil quality. At the landscape level this includes the effects of land management and land use change on soil and stream water chemistry, and watershed integrity. My current research includes:

1. -Indicators of forest ecosystem functions.
2. Functional Indicators, -The effect of land use change on biogeochemical cycles in the Brazilian Amazon.
3. -The effect of upland soil tillage for plantation establishment on carbon storage and nutrient availability.
4.

5. -Land use conversion effects on solution fluxes in streams of the Brazilian Cerrado.
6. -The effect of throughfall exclusion in a tropical forest on soil and soil solution interactions.
7. -The role of soil CO2 in mineral weathering and soil cation supplies.
