[Terrapreta] vascular elements

[folke Günther]

Isn't a discussion of using lignite or anthracite missing the point in some
ways?
There are two good reasons for adding char to the soil:

   1. Improving the soil
   2. Sequestering carbon dioxide from the atmosphere

Taking up inert carbon already present in deep ground for the sake of point
(2) above is meaningless
Adding it to soil for doubtful reasons is also meaningless.
Concentrate on biomass!
