Long-term Experiments

During the past 50 years, the continuous development of production techniques and strategies in organic farming has resulted in increased yields. Nevertheless there is significant scope for optimization and to systematically refine the concept of eco-functional intensification within organic farming systems in developed and less developed regions alike. Long-term experiments provide the platform for research pursuing the main questions:

  • How productive are various low-external-input, organic and soil-conserving farming systems and techniques compared to both high-input and traditional ones in the long-term?
  • How can conservation tillage practices be taken up in organic crop rotations without the use of chemical nitrogen and herbicides?
