Prof.Judith Tisdall is widely experienced in basic and applied research in soils. In 2012, she was awarded the JK Taylor Gold Medal for excellence in research and communication. She is the leading scientist on aggregate hierarchy, and management that increases stable aggregation. Her paper Organic matter and water-stable aggregates in soils in the Journal of Soil Science (Tisdall and Oades 1982; 80% contributed by the first author) is the most cited paper (2714 citations) in 68 years of the European Journal of Soil Science (and predecessor Journal of Soil Science); the paper was re-published as Landmark paper in the European Journal of Soil Science (2012). She was the first to show a) the effect of mycorrhizal hyphae on soil aggregation, and b) that the mechanisms of salt-exclusion and potassium-exclusion in grapevine rootstocks operate in the roots. Her 52 papers have been cited a total of 4438 times in the scientific literature.
