Field Trials

The Julius-Kühn-Field is home to some of the oldest agricultural field trials in Germany and Europe: The Eternal Rye and the Fertilization Trials by Karl Schmalfuß. In Merbitz, a new field trial with focus on climate change adaptation will be installed soon.

  • The Eternal Rye trial, laid out in 1878 by Julius Kühn. Today, it is the oldest continuing field trial in Germany and the second oldest in the world.
  • The long-term fertilization trials founded by Karl Schmalfuß in 1949 investigate the effects of different amounts and types of lime, potassium, phosphate, mineral and organic fertilizers.
  • In a new organic crop rotation trial oil crops and legumes will be tested for sustainable and climate-resilient cropping systems.
