Marion Jackson, UW-Madison Soil Scientist Dead At 88

Marion L. Jackson, emeritus professor of soil science at the University of Wisconsin-Madison, died Saturday, Dec. 21, 2002. He was 88 years old.

Jackson came to the UW-Madison in 1937 as a graduate student, and earned his doctorate in soil science in 1939. He worked as a post-doctoral fellow and instructor until joining the faculty of the soil science department in 1942.

Jackson studied the weathering of minerals in soils, and the absorption of ammonia as affected by soil pH, texture, moisture and tilth. He also studied nutrient losses from runoff and their effects on stream and lake pollution, and response of corn to nutrients in interaction with stand density. He developed the leading weathering sequence for clay minerals and a widely used set of methods for soil mineral analysis, and made many other contributions to the understanding of soil minerals, their chemical properties, and their roles in the environment.

Jackson published 241 research reports and two textbooks, along with 14 chapters in other books. He trained 59 Ph.D. students and 18 M.S. students, and advised 37 postdoctoral scholars from countries around the world.

In 1974 he was selected Franklin Hiram King Distinguished Professor. In 1986 he received the Distinguished Career Award of the Soil Science Society and the Bouyoucos Soil Science Distinguished Career Award. He was elected to the National Academy of Sciences in 1986.

Jackson was a member of the American Society of Agronomy, the Soil Science Society of America (president, 1967-68), the International Society of Soil Science, the Clay Mineral Society (president, 1966-67), the International Clay Mineral Society, the Mineralogical Society of America, the American Association for the Advancement of Science, and the Environmental Geochemistry and Health Society.

Jackson was a fellow in the American Association for the Advancement of Science, the Soil Science Society, the American Society of Agronomy, and the Mineralogical Society of America.

Jackson is survived by his wife, Chrystie (Bertramson); three children, Marjorie Jackson of Omaha, Neb., Ginny V. L. (Bruce) Conlon of Dallas, Texas, and Stan Jackson (Beth) of Fairfax, Va.; daughter-in-law, Lorrie Leja Jackson, Cheboygan, Mich.; seven grandchildren and two great-grandchildren. His son, Douglas M. Jackson, M.D., predeceased him.

A service in memory of Jackson will be held Saturday, Feb. 1, 2003, at 10 a.m. at Asbury Methodist Church, Madison. Memorials may be made to the Oakwood Retirement Fund, Asbury Methodist Church, or the Department of Soil Science at the University of Wisconsin-Madison.
