PEYVE, YAN VQL'DEMAROVICH (Agricultural Chemist) 



Y. V. Peyve was born August 3, 1906. He graduated in 1929 

 from the Moscow Agricultural Academy of K. A. Timiryazev. 

 In 1930-1944, he worked in the All-Union Scientific Research 

 Institute of Flax; in 1944-1950 he was President of the Latvian 

 Agricultural Academy. Peyve has been a doctor of sciences 

 and a professor of agrochemistry since 1940. He has been an 

 Academician of the Latvian S.S.R. Academy of Sciences from 

 1946 and in 1951 was made President. In 1953 he was elected 

 Corresponding Member of the U.S.S.R. Academy of Sciences. 

 Peyve has been a Deputy to the U.S.S.R. Supreme Soviet, fourth, 

 fifth, and sixth convocations. In 1949 he became a member of 

 the Soviet Committee in Defense of Peace, and in 1951 Chair- 

 man of the Latvian Republican Committee on the Defense of 

 Peace. He was elected in 1958, Chairman of the Council of the 

 Nationalities of the U.S.S.R. Supreme Soviet. 



Peyve' s main work is in agrochemistry, biochemistry, soil 

 science, and increasing harvest of industrial crops such as flax 

 and sugar beets. He established methods of determining mobile 

 forms of potassium, aluminum, humous acids, and microele- 

 ments in soils of the Podzol zone and invented apparatus for 

 making these analyses under production laboratory conditions 

 on collective farms. He worked out principles of differential 

 use of fertilizer for flax and other agricultural crops in relation 

 to soil conditions. Peyve also studied use of microelements 

 such as boron, molybdenum, zinc, and copper and plant nu- 

 trition and cobalt, copper, zinc, molybdenum and boron in the 

 soils of the Latvian S.S.R. and U.S.S.R. 



In 1961 Y. V. Peyve published a monograph "Biochemistry of 

 the Soils" in which he presents experimental works dealing with 

 biochemistry of soil humus, biochemistry of microelements and 

 other elements of plant nutrition as well as biochemistry of 

 enzymes. 



In 1961 he was a Candidate Member of the Central Committee 

 of the Communist Party.
