Vsevolod Mavrikievich Klechkovsky (Все́волод Маври́киевич Клечко́вский), also transliterated as Klechkovskii and Klechkowski (November 28, 1900 in Moscow - May 2, 1972 in Moscow) 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.[1][2] He was one of the first to study plant nutrition using radioisotopes, for which he received a 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.[3]

Klechkovsky also studied theoretical chemistry, and proposed a theoretical justification of the empirical Madelung rule for the ordering of atomic orbital energies.[4][5] This rule is therefore sometimes called Klechkovsky's rule, especially in Russian and in French sources.
