Hi Albert

 

yes you are correct.  I spent a month with Brazilian scientists at Inmetro near Rio working on this.  We have published a couple of papers around the role of minerals especially clay that have been deposited on the surface of the wood and grass biochar.

 

I suggest people look at the BBC series "Around the world in 80 gardens" and the episode on Brazil and the subsection on Terra preta when an Indigenous woman shows how she makes biochar amendments. 

 

I contend that the present methodology from Vera and Puro doesn't take into consideration composite oranomineral based biochars  which can be more effective both from plant response and from persistence.

Joey, I think there are also some Brazilian studies to this effect. Many years ago I attended a conference on the terra preta soils in Manaus and there were papers given drawing the connections with clay, including calcined clay and pottery shards from excavated terra preta digs, and looking at the synergies clay provides to biochar in soil.

Hi Gabriel 

 

I started my biochar career when I taught Indigenous Australians ceramics, engineering and manual arts.  They taught me how to make and use biochar.  But the most valuable lesson they taught me was clay and biochar are synergistic.  The yin and the yang the white and the black.  They use this combination in medicine, for cooking and in art.  From a scientific perspective, we have found that pretreating biomass with clay and or postreating the biochar with clay improves it properties.   Pretreating with clay helps to increase yields and condenses out organic compounds on the clay that helps seeds germinate and provides food for microbes.  We also found that bacteria that can fix carbon and nitrogen grow at the interface between the carbon matrix and the clay platelets.  Because kaolin clay has a much higher AEC and bentonite clay a higher CEC than biochars then you increase the nutrient holding capacity.

 

But pretreating with clay also increases persistence of the biochar.  The present methodologies don't take this into account.
