INRES - Plant Nutrition

Plant nutrition is defined by the German Society for Plant Nutrition (Deutsche Gesellschaft für Pflanzenernährung e.V.) as the study of the functions and dynamics of nutrients in plants, soils and ecosystems and of plant metabolic processes with the aims of

  • to improve the growth of plants
  • to increase the quality of harvested products
  • optimize soil fertility
  • to promote the recycling of nutrients
  • reduce the input of production resources
  • minimize the environmental impact of fertilizer use

These goals are pursued by the Plant Nutrition Division of INRES with the Chair of Ecopysiology of Plant Nutrition (Prof. Dr. Gabriel Schaaf), the Chair of Plant Nutrition in the Tropics and Subtropics (Prof. Dr. Mathias Becker) and in various working groups.

Phosphorus Absorption Improved and Zinc Content Increased

A new variety of rice that is adapted to life in low-phosphorus soils, that contains an exceptionally large amount of zinc and that was developed specifically for the conditions in Madagascar where it is grown, has recently been certified in the country. The variety was created under the leadership of plant scientist Professor Matthias Wissuwa from the Japan International Research Center for Agricultural Sciences (JIRCAS) and the PhenoRob Cluster of Excellence at the University of Bonn which he joined as a visiting professor in spring 2023, together with the Africa Rice Center and the National Centre of Applied Research for Rural Development in Madagascar (FOFIFA).


The 5th INRES - Minisymposium (INRES Day) will take place on August 24 on the Campus Poppelsdorf in the lecture hall center "CP1-HSZ", Endenicher Allee 19C, 53115 Bonn, Germany.

PhD students at the International Grassland Congress in Covington

During the 25th International Grassland Congress in Covington, Kentucky, our two PhD students Florian Männer and Lisa-Maricia Schwarz presented some of the results of their studies.

Additive to make slurry more climate-friendly

Livestock farming produces large quantities of greenhouse gases, especially methane, which is particularly harmful to the climate. Among other things, it escapes during the storage of animal excrement, the slurry. A study by the University of Bonn now shows that methane emissions can be reduced by 99 percent through simple and inexpensive means. The method could make an important contribution to the fight against climate change. The results have now been published in the journal Waste Management.
