- Hydro-biogeochemistry of nutrients in the soil environs. Currently, my main research trust is the fate and transport of P from altered wetland soils to waterways. The research encompasses detailed laboratory investigations including sequential extractions, adsorption-desorption isotherms, micro-cosmos experiments and development of nutrient sensors. The field studies include fully automated lysimeter station of 48 lysimeters (1 x 1 x 1.5 m) where farming practices are being evaluated. Conducting large field experiments of several hectares that simulate changing groundwater conditions, boundary conditions and land use change.
- Developing constructed wetlands (CW) for studying catastrophic dieback of wetland plants and the use of CW system for waste water treatment.
- Studying snow dynamics in high Mediterranean mountains (snow in warm region), and estimating the SWE distribution on Mt. Hermon.
- Studying alpine soil processes in Colorado Front Range. Currently, the study is evaluating the hypothesis that anthropogenic N loading has increased soil acidity, affects the constituents of the cation exchangeable structure (increased Al & decrease Ca+Mg). These changes may lead to increase P solubility and to ecosystem change.
