His most influential work was on the soils of the Netherlands De bodem van Nederland (in two volumes 1907, 1927). His son Ferdinand Alexander van Baren (1905-1975) also became a soil scientist.

He wrote a biography of W.C.H. Staring (1808-1877). He was a founding member of the Geological Society of the Netherlands and Colonies. In 1931 he wrote on the development of soil on the volcanic island of Krakatoa.[1] Over twenty years he worked on a two volume textbook on the soils of the Netherlands. He married Jeanne Pauline van de Meijer in 1902 and they had three sons including[2] Ferdinand Alexander van Baren who studied soil science under Cornelis Hendrik Edelman and became a specialist on tropical soils.[3]
