Historical Highlights from 75 Years of the Soil Science Society of America

摘要

November 18, 2011 marks the 75-year anniversary of the Soil Science Society of America (SSSA). This timeline was developed as part of the celebration of that milestone and was assembled in two parts. The items from 1931 through 1985 were originally assembled for the SSSA 50th anniversary in 1986. SSSA records don't indicate who developed the 50th anniversary timeline, but it was likely the SSSA historian at the time, Sterling Olsen. The items from 1987 through 2011 were assembled by Eric Brevik for the 75th anniversary, as were the introductory remarks and graphs. The 1986 entry, given the knowledge that the original timeline was assembled before 1986 was completed, contains items contributed by both authors.
