Which German chemist identified nitrogen as a principal plant nutrient and is considered the father of the Fertilizer Industry?

• A. Louis Pasteur
• B. Justus Freiherr von Liebig
• C. Antoine Lavoisier
• D. Nicolas-Theodore de Saussure

Answer: (B)

The key idea is understanding who first linked nitrogen to plant nutrition and sparked the modern fertilizer industry. Justus von Liebig, a German chemist from the 19th century, showed through systematic plant-growth studies that crops rely on specific mineral elements, with nitrogen being essential for proteins, chlorophyll, and overall growth. He pushed the practical side of this insight by promoting chemical fertilizers to supply nitrogen and other nutrients, which transformed agriculture and gave rise to the modern fertilizer industry. That combination of identifying nitrogen’s crucial role in plant nutrition and driving a new approach to soil fertility is what earned him the title of father of the Fertilizer Industry. Other scientists mentioned made major contributions to chemistry and biology, but they did not establish nitrogen as a principal plant nutrient or catalyze the fertilizer industry in the way Liebig did.
