Institut für Pflanzenernährung

Did the soil whisper secrets to Margarete von Wrangell? Here, at the Institut für Pflanzenernährung, it’s easy to believe. This institute, nestled within the University of Hohenheim in Stuttgart, has a history as rich as the earth it studies. Founded in 1923 amidst the food shortages of the Weimar Republic, its first director, Margarete von Wrangell, was a pioneer. She wasn’t just a brilliant scientist focused on phosphate and its vital role in plant growth. She was also the first female professor in Germany, a testament to her unwavering determination. The Institut für Pflanzenernährung wasn’t just a lab. It was a hub of innovation where Wrangell developed the “Aereboe-Wrangell fertilization system.” This system aimed to unlock the hidden potential of phosphates in the soil, turning them into nourishment for plants. Wrangell also embraced new technologies, proving that plants draw sustenance from the soil’s liquid, not the soil itself. After Wrangell’s passing in 1932, Kurt Maiwald took the helm. The era of manure heaps began. Maiwald, known for his international studies, delved into the effects of manure on plant growth. He even experimented with urban waste like sewage sludge, a forward-thinking approach for his time. The Institut für Pflanzenernährung continued to evolve under Gerhard Michael, who arrived from East Germany in 1960, just before the Berlin Wall rose. With post-war overproduction, Michael shifted the focus to food quality. He pioneered the use of isotope technology, delving into the intricate dance of nutrients within plants. Then came Horst Marschner in 1976, a man with a global vision. He brought international recognition to the Institut für Pflanzenernährung, collaborating with researchers worldwide and focusing on the complex relationship between plants and nutrient-poor soils. His work extended to China, West Africa, and Turkey, reflecting his dedication to improving global agriculture. From 1996 onwards, the institute embraced the world of molecules and micronutrients, with Nicolaus von Wirén introducing molecular biology to the research mix. Today, under Uwe Ludewig, the Institut für Pflanzenernährung continues to explore the intricate world of plant nutrition, tackling challenges like phosphorus recovery and sustainable agriculture. This institute, with its roots in a quest for food security, has blossomed into a center for cutting-edge research. It’s a place where the whispers of the soil are translated into scientific breakthroughs, where the legacy of Wrangell and her successors continues to inspire.
