Welcome to the Institute of Applied Plant Nutrition (IAPN). An increasing world population, changing dietary habits and climate change place great demands on agricultural research. Increasingly, the focus in agriculture is on questions pertaining to the efficient use of arable and pasture land, of water and of plant nutrients.
The IAPN addresses these issues. We are committed to researching the role of intelligent fertilization management in handling these global challenges, and to provide solutions.
We see ourselves as an interface between science and agricultural practice. The development of approaches to an efficient transfer of knowledge is therefore another important concern. We aim to pool knowledge in a global network, creating synergies for successful research and practical implementation of these research results.
