Before Biosa

In the mid-1980s, he traded a bustling business life to establish himself as a biodynamic farmer, and it was his quest for sustainable technologies for organic farming that led him to research and experiment with fermentation and the impact of microorganisms on plant growth, as well as the health of animals and humans. "I could see that microorganisms brought new life in an effective and sustainable way, so I set out to learn more about them. The goal was to develop products with microorganisms that were both organic, effective, and sustainable

I was fascinated by the fact that the growth and strength of plants could be significantly increased by adding microorganisms to the soil
