William Albrecht
William A. Albrecht (1888–1974) PhD,〔(Springerlink, Obituary of William A. Albrecht, 1974 )〕〔(International Federation of Organic Agriculture Movements - profile of William Albrecht )〕 Chairman of the Department of Soils at the University of Missouri, was the foremost authority on the relation of soil fertility to human health and earned four degrees from the University of Illinois. As emeritus Professor of Soils at the University of Missouri he saw a direct link between soil quality, food quality and human health. He drew direct connections between poor quality forage crops, and ill health in livestock and from this developed a formula for ideal ratios of cations in the soil, the Base Cation Saturation Ratio. While he did not discover cation exchange in the soil as is sometimes supposed, he may have been the first to associate it with colloidal clay particles.
Twenty years before the phrase 'environmental concern' crept into the national consciousness, he was lecturing from coast to coast on the broad topic of agricultural ecology. (C. Edmund Marshall, In Memoriam, 'Plant and Soil' vol 48.)〔
==Early life==
William Albrecht was born of German ancestry on a farm on the prairie of north central Illinois in the Mid-West United States. After attending the local school he progressed via preparatory school to the University of Illinois where he obtained a B.A. degree in liberal arts.This led to a position teaching Latin and other subjects at Bluffton University, Ohio.〔
Albrecht later returned to Illinois to gain a B.S. degree in biology and agricultural science. He then started graduate research in Botany whilst also teaching in the department of botany. This period was key to his lifelong devotion to scientific study of plant physiology and agriculture. It enabled him to take a microbiological view of plant structure whilst addressing the soil as a variable environment (either favourable or unsuitable). He presented his doctoral research in 1919, and it was published in the journal ''Soil Science'' in 1920 titled 'Symbiotic nitrogen fixation as influenced by nitrogen in the soil' His paper concluded that the nitrogen level in soil had no significant effect on fixation by legumes.〔
