Justus Freiherr von Liebig [a] (12 May 1803 – 20 April 1873) [2] was a German scientist who made major contributions to the theory, practice, and pedagogy of chemistry, as well as to agricultural and biological chemistry; he is considered one of the principal founders of organic chemistry. [3]
A kaliapparat. A kaliapparat is a laboratory device invented in 1831 by Justus von Liebig (1803–1873) for the analysis of carbon in organic compounds. [1] The device, made of glass, consists of a series of five bulbs connected and arranged in a triangular shape.
Prior to Pasteur's research on fermentation, there existed some preliminary competing notions of it. One scientist who had a substantial degree of influence on the theory of fermentation was Justus von Liebig. Liebig believed that fermentation was largely a process of decomposition as a consequence of the exposure of yeast to air and water. [4]
More significantly, Liebig analysed biological growth as constrained by limiting factors such as a shortage of phosphorus, potassium or nitrogen. His view is called Liebig's law of the minimum. As the nineteenth century progressed so did soil science and its promulgation by farm journals such as those published by Luther Tucker. [5] [6] [7]
Freiherr Justus von Liebig (1803-1873) was a German chemist who made major contributions to agricultural and biological chemistry, and worked on the organization of organic chemistry. As a professor , he devised the modern laboratory -oriented teaching method, and for such innovations, he is regarded as one of the greatest chemistry teachers of ...
The early concepts of soil were based on ideas developed by a German chemist, Justus von Liebig (1803–1873), and modified and refined by agricultural scientists who worked on samples of soil in laboratories, greenhouses, and on small field plots. The soils were rarely examined below the depth of normal tillage.
Justus von Liebig (1803 – 1873), German chemist and founder of industrial agriculture, claimed that England had "stolen" 3.5 million skeletons from Europe to obtain phosphorus for fertilizer. In Paris, as many as one million tons of horse dung was collected annually to fertilize city gardens.
Liebig's law of the minimum, often simply called Liebig's law or the law of the minimum, is a principle developed in agricultural science by Carl Sprengel (1840) and later popularized by Justus von Liebig. It states that growth is dictated not by total resources available, but by the scarcest resource (limiting factor).
