Gerard W KorthalsGerard Korthals is an expert on soil biology, soil health, tropical ecology, ecotoxicology and nematology. He started his career as a biologist at the Free University in Amsterdam. He performed his PhD (Pollutant induced changes in terrestrial nematoe communities) at the Agricultural University of Wageningen under the supervision of Tom Bongers. Since 1999 he is a senior scientist for Wageningen Plant Research (WUR). Most important themes focus on the development of durable agricultural systems, soil health, biodiversity, and sustainable land use. His special interest lies within soil ecology and soil health, focusing on how the whole soil food web, with a special focus on nematode communities (plant parasitic end non plant parasitic), may change due to management, disturbance, climate, set-aside and management practices, in relation to plants (natural vegetation and crop productivity).
