Max Trénel (born May 8, 1889 in Berlin ; † December 22, 1966 there ) was a German soil scientist .

Live and act

Trénel studied physics and chemistry at the University of Berlin from 1919 and received his doctorate there in 1923 with a dissertation on the breakdown of nitro-trimethylene glycol. As an assistant at the Physics Institute of the Technical University of Berlin , he developed a device for the electrochemical determination of the hydrogen ion concentration in 1923. In 1924 he got a job as a chemist at the Prussian State Geological Institute in Berlin. In 1927 he completed his habilitation at the Agricultural University in Berlin with the text The scientific foundations of the soil acid question and its practical application in practical agriculture .

The problems of soil acidity in connection with the study of soil fertility and soil genesis were henceforth the focus of Trénel's scientific work. In 1932 he was appointed associate professor. From 1935 he headed the Institute for Soil Mapping at the Geological State Institute in Berlin. From 1946 to 1959 he taught at the Humboldt University in Berlin, initially as a professor of agricultural and forestry soil science, and since 1951 as professor and director of the Institute for Plant Nutrition, Soil Chemistry and Soil Biology. During this entire time he mainly dealt with questions of lime fertilization, the role of aluminum and magnesium salts in the soil and the biological importance of trace elements .

Trénel was the editor and co-translator of several Russian agricultural science manuals. His contributions to the scientific history of agriculture are noteworthy. The Agricultural and Horticultural Faculty of the Humboldt University in Berlin awarded him an honorary doctorate in 1959.

Max Trénel died in Berlin in 1966 at the age of 77. His grave is in the forest cemetery in Zehlendorf .
