Carl Sprengel
From Wikipedia, the free encyclopedia
- There is another botanist from this time, Kurt Sprengel.
Karl or Carl Philipp Sprengel (born 1787; died 1859) was a German botanist.
Sprengel worked under Albrecht Daniel Thaer (1752-1828) in Celle. He then worked from 1804-1080 with Heinrich Einhof (1778-1808) in Möglin on agricultural studies.
From 1821-1828 he studies natural sciences in Göttingen, where he eventually became professor.
Sprengel was the first to formulate the theory of minimum in agricultural chemistry, meaning that plant growth is limited by the lowest amount of an essential nutricient. This rule, often falsely awadrded to Justus von Liebig, was only made popular by Liebig.
