from Wikipedia, the free encyclopedia

Wilhelm Schneidewind (born June 22, 1860 in Osterweddingen , † April 18, 1931 in Halle an der Saale) was a German agricultural chemist.

Life

As the son of a landowner, Schneidewind studied natural sciences, especially chemistry, from 1882 at the Friedrichs University in Halle , the Albert Ludwig University of Freiburg , the University of Rostock and the Georg August University of Göttingen . He became a member of the Corps Palaiomarchia and the Corps Rhenania Freiburg . In 1888 he received his doctorate in Göttingen. Then he was assistant and head of department at the agricultural chemical test station in Halle (Saale). In 1902 he succeeded Max Maercker as director of this station. At the same time he took over the professorship for agricultural chemistryat the University of Halle. In 1925 he retired. He is buried in Halle's Stadtgottesacker .

Research services

Schneidewind's main areas of work included extensive analytical activities, the evaluation of fertilizers and animal feed, seeds, milk and dairy products, as well as studies of soils, water and agricultural crops. His main interests, however, were questions of plant nutrition and fertilization . At the Lauchstädt experimental farm in 1902, together with his administrator W. Gröbler, he set up a field fertilization test with the aim of researching the long-term effects of organic and mineral fertilization on the yields of crops, the quality of the harvested products and soil fertility . Called the static fertilization test in Bad Lauchstädt , this test is one of the most important permanent field tests in the world.

Most of the results of his fertilization tests, Schneidewind published together with other coworkers in the booklet series of works of the German agricultural society (1908-1923). Many of his practice-oriented contributions appeared in the reports on the experimental economy Lauchstädt published by the Chamber of Agriculture for the Province of Saxony (1902-1925).

Schneidewind crowned his scientific life's work with the textbook The Nutrition of Agricultural Cultivated Plants , which appeared for the first time in 1915 and five further editions followed by 1928. It was highly valued by scientists, students of agriculture and also by farmers and was one of the authoritative standard works on plant nutrition and fertilization, especially between the two world wars.
