Klaus Strüber, an organic farmer and mechanical engineer fro the farm Hollergraben is building two Open Source tools for gardening:
- Cultivator for Horses “Eco Flow” to prepare fine seedbeds for vegetable cultivation. It should work better than the classical ones on the market.
- Onion Planter as an alternative to manual work and expensive market tools. One person should be able to push it, and gently and quickly plant onions with it.
