Improve nutrient-use efficiency in agro-ecosystems

Plant Nutrition

One of the challenges of this century is to sustainably meet the needs of the growing world population. Increased food production goes along with an increased nutrient demand for crops. Severe problems arise when too little or too much nutrients are added to agro-ecosystems. Using the most recent tools from plant and soil sciences, the Group of Plant Nutrition unravels mechanisms controlling nutrient cycles in the soil plant system, in order to contribute to the development of agricultural systems that maximize nutrient use efficiency and limit nutrient losses to the environment.

We study abiotic and biotic processes determining the availability of nutrients for plants. Besides classical methods, we use in our research radioactive and stable isotopes, mycorrhizal cultures, molecular markers and enzymatic methods. Research projects address nutrient-limited and nutrient-rich situations in the temperate and tropical zone and consider interactions between different nutrients. In nutrient-poor systems we elaborate biological approaches to alleviate phosphorus and nitrogen limitations while in nutrient-rich systems the focus is on optimizing nutrient recycling to crops.
