Carl Sprengel
From Wikipedia, the free encyclopedia
- There is another botanist from this time, Kurt Sprengel.
Karl or Carl Philipp Sprengel (March 29, 1787 – April 19, 1859) was a German botanist from Schillerslage (now part of Burgdorf, Hanover).
Sprengel worked under Albrecht Thaer (1752-1828) in Celle. He then worked from 1804 to 1808 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 nutrient. This rule, often falsely awarded to Justus von Liebig, was only made popular by Liebig. Sprengel died in Regenwalde (Resko), Pomerania.
