Ernst Tamm

from Wikipedia, the free encyclopedia

Ernst R. Tamm (born September 15, 1897 in Egelsbach ; † July 27, 1983 in Wiesbaden ) was a German crop scientist with a research focus on agricultural climatology .

Life

Tamm studied at the Agricultural University in Berlin from 1919 and received his doctorate there in 1922 with a dissertation on the development of forage production in Germany. He then worked as a scientific assistant at the institute for arable and crop production at this university and completed his habilitation in 1927 with a paper on problems in electrical culture . As a private lecturer, he continued to work at this institute. In the following years he mainly dealt with questions of soil cultivation, field test technology and new cultivation methods of grain.

In 1933, Tamm was appointed associate professor. From then on he devoted himself specifically to the field of agricultural climatology. In a contribution published in 1933, “ Thoughts and suggestions for the establishment of a plant weather and climate station ”, he presented a concept for researching the plant climate from the point of view of agriculture. In Dahlem , he set up a plant climate station equipped with the latest measuring devices and examined the air and soil temperatures, the relative humidity, as well as the air movements and radiation conditions in crops . In 1936 he published his first results in a groundbreaking study and specified the tasks of future "agricultural plant climate research". The Second World War brought his promising research projects to an abrupt end.

After 1945, Tamm played a major role in the reconstruction of the Institute for Arable and Plant Cultivation in Berlin-Dahlem, which was destroyed in the war. In 1951 he was appointed full professor to the chair for arable and crop production at the Faculty of Agriculture at the Technical University of Berlin . Until his retirement in 1965 he dealt with a variety of problems in the field of arable and crop production. However, his research focus remained on agricultural climatology. With a largely fully automatic climate station, he set new standards in researching the plant climate. His experimental investigations yielded new insights into the relationships between the weather and the yield of agricultural crops. Since 1950 he has published numerous articles on this in the “Zeitschrift für Acker- und Pflanzenbau”.

From 1929 to 1933, Tamm was editor or co-editor of the magazine “Progress of Agriculture” and from 1929 to 1934 co-editor of the “Scientific Archive for Agriculture”. He achieved great merits with the translation and publication of the standard work “ Special Plant Cultivation ” (7th edition, 1930) by the Russian agricultural scientist Dmitri Nikolajewitsch Prjanischnikow .
