Vsevolod Mavrikievich Klechkovsky (Russian: ???´????? ?????´?????? ??????´?????; also transliterated as Klechkovskii and Klechkowski; November 28, 1900 – May 2, 1972) was a Soviet-era agricultural chemist known for his work with radioisotopes. He graduated in 1929 from the Moscow agricultural academy and worked there from 1930.
He became a professor in 1955, and an academician of the All-Union Academy of Agricultural Sciences of the Soviet Union (known as VASKhNIL) in 1956. His use of isotopic labeling in the advance of soil chemistry led to his being considered a founder of agricultural radiology.
He was one of the first to study plant nutrition using radioisotopes, for which he received the Stalin Prize in 1952 along with his academy co-workers.
He studied the behavior of heavy nuclei daughter isotopes in soils. Following the 1957 Kyshtym disaster, Klechkovsky led the research projects studying the long-term effects of radioactive contamination at the site.Klechkovsky also studied theoretical chemistry, and proposed a theoretical justification of the empirical Madelung rule for the ordering of atomic orbital energies.
This rule is therefore sometimes called Klechkovsky's rule, especially in Russian and in French sources.
