Project Details


Grasslands are invaluable to enhance the sustainability of agricultural production by providing ecosystem services, such as carbon sequestration. Additionally, when being feed for ruminants, grass is converted into human edible protein and reduces food-feed competition. However, in the process ruminants produce methane. Thus, an ideal solution is the design of grasslands that reduce enteric methane and yet maintain or increase ecosystem services. This project will evaluate the potential of including tannin rich forages in grasslands to reduce methane emissions from ruminants and simultaneously increase soil organic carbon stabilization with tannins that are excreted via rhizodeposition. The project will focus on why previous results have been highly variable and aims at understanding the mode of actions from tannins, using an innovative system approach using biochemistry, ruminant nutrition, soil science and genetics. This shall enable the prediction and use of their bioactivity.
