Dr. Geza Racz, Professor Emeritus

Geza Racz

Dr. Racz's training includes a B.Sc. in agriculture (major soil science) and M.Sc. and Ph.D. degrees with specialization in soil chemistry and inorganic chemistry.

Current Research Interests:

Dr. Racz's main areas of research and expertise are related to the reactions and fate of various elements in soil as related to land productivity, sustainability and food quality. Studies include:

Reactions, mobility and fate of nitrogen and phosphorus

  • The solid phases formed and surface reactions between phosphorus and soil constituents and the phytoavailability of soil and fertilizer phosphorous as affected by soil characteristics and environmental conditions have been a major focus of study
  • The effect of placement, time of application, form of nitrogen fertilizer and use of inhibitors on mobility and phytoavailability of nitrogen fertilizers on various soil types is currently under investigation.

Reactions and phytoavailability of minor elements

  • The precipitation and adsorption reactions of elements such as zinc and copper with soil constituents such as the iron and aluminum oxides and the phytoavailability of these elements as affected by various plant and soil factors are elucidated

Fate and bioavailability of heavy metals

  • The fate of bioavailability of heavy metals, particularly cadmium, from indigenous and anthropogenic sources and effect on food quality is being studied
