- Carl Sprengel
:"There is another botanist from this time,
Kurt Sprengel ."Karl or Carl Philipp Sprengel (
March 29 1787 –April 19 1859 ) was a Germanbotanist fromSchillerslage (now part ofBurgdorf, Hanover ).Sprengel worked under
Albrecht Thaer (1752-1828) inCelle . He then worked from 1804 to 1808 withHeinrich Einhof (1778-1808) inMöglin 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.Works
