Vsevolod Mikhailovich Klechkovsky: A Pioneer in Agrochemistry
Early Life and EducationVsevolod Mikhailovich Klechkovsky was born on November 15 (28), 1900, in Moscow, Russia, to the renowned agronomist Mikhail Mikhailovich Klechkovsky. In 1929, he graduated from the Moscow Agricultural Academy (MSHA).
Career in Agrochemistry
Klechkovsky began his career at MSHA in 1930, where he rose through the ranks to become a professor in 1955. As an academician of the All-Union Academy of Agricultural Sciences (VASKhNIL) in 1956, he played a pivotal role in the field of agrochemistry.
His groundbreaking research focused on the application of the method of labeled atoms in agrochemistry. He pioneered extensive studies on plant nutrition using radioactive isotopes and developed numerous instruments for this purpose.
Notable Contributions
Klechkovsky made significant contributions to the study of the behavior of heavy nuclear fission products (isotopes of strontium, yttrium, and zirconium) in soils. He also delved into the physicomathematical justification of the phenomenon of periodicity.
In particular, he introduced the concept of (n + l) domains of electronic states in atoms in 1951 and formulated the (n + l) rule for the formation of electron configurations of atoms as the nuclear charge increases (Klechkovsky's rule).
Legacy and Impact
Vsevolod Mikhailovich Klechkovsky passed away on May 2, 1972, leaving behind a legacy of groundbreaking research and innovative advancements in agrochemistry. He was laid to rest at the Vagankovskoye Cemetery in Moscow.
His daughter, Vera Vsevolodovna Klechkovskaya, followed in his footsteps as a distinguished physicist and crystallographer. She holds a Doctorate in Physical and Mathematical Sciences and is the Head of the Crystallography Laboratory at the Institute of Crystallography of the Russian Academy of Sciences.
