Soil Science of Tropical and Subtropical Ecosystems

Research interests

  • Impact of global change processes (e.g. increase in nutrient deposition, land-use change, changes in rainfall levels) on soil carbon and nitrogen cycling, net primary production, leaching losses, and biogenic trace gas fluxes

  • Ecosystem functions of agroforestry systems

  • Landscape-scale assessment of crop yield and of trade-offs between crop production and associated environmental effects

  • Landscape-scale quantification of soil carbon changes and greenhouse gas fluxes from conversion of tropical natural ecosystems (e.g. rainforest) to agricultural production systems

  • Soil productivity recovery of degraded lands in the tropics

  • Applications of stable isotopes, e.g. 13C and 15N, for quantifying carbon and nitrogen fluxes among soil, plant, water and air
