He was inducted into the Mid-Atlantic Association of Professional Soil Scientists (MAPSS) in 1989 as its first honorary member.

In 1967 Simonson became the editor-in-chief of soil science journal Geoderma where he published numerous articles.

After serving as an Assistant Professor of Soils at Iowa State College from 1938–1942,  he worked in the USDA federal soil survey programs, first with the Bureau of Chemistry and Soils and then with the Soil Conservation Service.  He served as Principal Soil Correlator for the Southern United States, Chief Soil Scientist for Pacific Surveys, 1947–48; Assistant Chief of Soil Surveys, 1949–52; and Director for Soil Classification and Correlation, 1953–1971.

Roy W. Simonson (September 7, 1908 – November 2, 2008) was a scientist, professor, and writer who studied soil across the United States and on islands in the Western Pacific. He taught at Iowa State College from 1938 to 1943 and then became a Soil Correlator for the United States Department of Agriculture Division of Soil Survey. After World War II, Simonson worked for the Military Geology Unit to map soils on islands in the Western Pacific.
