Joseph Hellriegel

Joseph Hellriegel was a notable German agronomist and chemist in the late 19th century, best known for his work on soil science and plant nutrition. He conducted important research on how nutrients in the soil affect crop growth, particularly nitrogen and its role in enhancing agricultural productivity. Hellriegel’s findings contributed to the understanding of how crops can benefit from nitrogen-fixing bacteria, which naturally enrich the soil. His work laid foundational principles for modern agricultural chemistry, helping farmers improve yields and promote sustainable farming practices.
