Research stations

The Institute of Agricultural and Nutritional Sciences owes the establishment of experimental fields and stables to Professor Julius Kühn. When he was appointed professor of agriculture at Halle University in 1862, he considered it necessary that the research base, namely experimental fields and stables, was made available to him. With the creation of the pet garden and a plant breeding garden as well as the establishment of the first long-term fertilization experiment, Julius Kühn laid the foundation for the current teaching and experimental stations of the institute in 1865. Then as now, this close connection between science and agronomic practice is intensively used for teaching and research.

The following teaching and experimental stations are part of the institute:

Long-term field experiments - "LTE hub Halle"

Long-term field experiments (LTEs) are a valuable data base and infrastructure for agricultural research. Established decades ago, they help to answer questions concerning plant nutrition and nutrient use, aiming for maximum crop yield in sustainable cropping systems. They can be used to understand the effects of management practices, such as fertilization and soil cultivation, and to reveal the influence of climate change on plant development and yield stability, and respective adaptation possibilities. Furthermore, LTEs provide valuable information about the long-term reactions of agro-ecological systems to changes in fertilization and land use. At the institute`s field stations Kühnfeld and Merbitz, there are running six long-term experiments.

Detailed information about the research hub on long-term field experiments can be found at:

Head of the LTE hub: Prof. Dr. Janna Macholdt
