Justus von Liebig

Justus Freiherr von Liebig was a German scientist who made major contributions to agricultural and biological chemistry, and is considered one of the principal founders of organic chemistry. He has been described as the "father of the fertilizer industry" for his emphasis on nitrogen and trace minerals as essential plant nutrients, and his formulation of the law of the minimum, which described how plant growth relied on the scarcest nutrient resource, rather than the total amount of resources available.
