From 1930 to 1933, Meyer worked as a docent at the University of Göttingen, and in 1934, he became a full professor at the University of Jena. Within the same year, he became a professor at the University of Berlin. In November 1934 he became a consultant for the Reich Ministry of Science and Education on the reformation of German agricultural education and research. Meyer was one of the key agricultural scientist and spatial planners of the Nazi era, and served as the chief editor of the main journals of the field.

In early 1940, the Reich Main Security Office (RSHA) produced, with Meyer's collaboration, the initial version of "Generalplan Ost" (General Plan East), a plan for the Germanization of Eastern Europe. Meyer's subordinates in RKF's creating the memorandum included geographer Walter Christaller and landscape architect Heinrich Friedrich Wiepking-Jürgensmann. From 1944 to 1945, the end of the war, Meyer served an officer in a Waffen-SS officer training school.
