In 2022, Kálmán Rajkai has been elected as a full member of the Hungarian Academy of Sciences (MTA). On 3rd May, the Assembly of Academics elected the new full, corresponding, external and honorary members of the Hungarian Academy of Sciences from among 110 researchers on the joint list of candidates.
Kálmán Rajkai was born in Budapest in 1951. He is a corresponding member of the MTA since 2016. He is research professor emeritus at the Institute for Soil Sciences, Centre for Agricultural Research, specialising in soil physics, water management and (plant) stress research.
With his working group, he has evaluated plant stress tolerance, mycorrhizal fungi and root activity in soil using the root capacity method he developed (Biosystem Engineering, 2017, 26, 599-605; Plant and Soil, 2020, 449, 423-437). The dependence of soil water-holding capacity on the amount of aerated soil surface area was demonstrated by computer simulation and validated by a specific measurement procedure he developed (Journal of Hydrology, 2020, 588, 125-131). He plays an important role in the education of young scientists. Since his election as a corresponding member, he is the author of 18 scientific publications, including three D1 and six Q1. His publications have been independently cited 1178 times, h-index: 18.
