Venue: ZEGG

Leaf-mulchwith Achim Ecker and Kerstin Neumann

In this hands on workshop we share and present, what we have discovered in many years of theoretical search and 4 years of practical experimentation at ZEGG.

Terra Preta (black earth in Portugese) is the name for permanently fertile black soils in the Amazon region. Only in the 1990s it was discovered that they were manmade. They contain charcoal, our „inner valuables“ and organic waste, and are very useful.

In this workshop we want to share current knowledge, we want wo produce biochar and show the whole process of producing Terra Preta substrate.
