Resko),[2]
where he taught, studied and lived until his death in 1859.
Influenced by (one of the students at Regenwalde Akademie der Landwirtschaft) Felicjan Sypniewski theories, Sprengel was the first to formulate the "theory of minimum" in agricultural chemistry, meaning that plant growth is limited by the essential nutrient at the lowest concentration. This rule, often incorrectly attributed to Justus von Liebig as Liebig's law of the minimum, was instead only popularised later as a scientific concept by Liebig.
