I started doing agricultural in 1975 with raised garden beds (hugelkultur) at the garden of my parents.
At 1990 I build a municipal composting facility.
First contact with permaculture was in 1991.
I learned about alpine permaculture from Sepp Holzer's courses.
I had made a lot of ponds and terraces at my own land.
I build my mud / wood house by myself.
I have experience with Terra Preta growing trials.
