The Park Grass Experiment, a National Capability supported jointly by the BBSRC and the Lawes Agricultural Trust, is the oldest experiment on permanent grassland in the world.
It studies the effects of fertilisers, organic manures and lime on continuous hay production and continues to show the impact of farming practices on grassland biodiversity.

Join us to learn about Park Grass:
• History, design and management.
• Contribution to ecological and environmental change research, including how grassland biodiversity bounces back from long-term nitrogen addition.
• ….and much more.
