Special Professional Position –recent
Main Research Interest – Physical Chemistry of Soil and Environmental Systems:
Advanced isotopic and
spectroscopy based methods to study nitrogen and phosphorus transformations in
soils and sediment; Special resent focus- Development of the Modified
Isotope Pairing Technique
MIPT to trace N-transformations in polluted
stream sediments with emphasis on N2O emissions;
In Situ Evaluation of Net
Nitrification Rate in Terra Rossa Soil Using a Fourier Transform Infrared -
Attenuated Total Reflection 15N Tracing Technique;
On line
monitoring in soil and water systems using MidIR based spectroscopy:
FTIR
based measurements for direct nitrate determination and soil identification
with ATR Devices
Soil identification using
FTIR-PAS
Nitrate determination in soils using Transmission through Anion Exchange
Membranes;
Long term effects of irrigation with reclaimed wastewater, special emphasis
on:
Nitrogen
transformations and nitrous oxide emmision
Microbial activity and
community change of ammonia oxidizers
Environmentally friendly
fertilization approaches (controlled release, precision fertilization) emphasis
on both investigation of mechanisms, evaluation approaches and modeling of
release;
Advances in Controlled Release of Fertilizers
Modeling Controlled Nutrient Release from a
Population of Polymer Coated Fertilizers: Statistically Based Model for
Diffusion Release
Models of nitrogen and phosphorus dynamics in soils under various agronomic practices, application of environmentally friendly fertilization approaches, irrigation with reclaimed effluents and soil/root interactions
