The "black earth" is primarily associated with the so-called Mutus Liber lineage which is concerned with Materia Prima. This is a quite distinct tradition from herbal alchemy (Paracelsean) and metallic alchemy. It is still a school of practical laboratory alchemy among fringe enthusiasts in Central Europe. This is the type of alchemy that tries to extract the Material Prima from the gross exudates of nature; manures, humus, dew etc. It doesn't usually use herbs or metals. It is agricultural. 
So I would be surprised to find the Voynich MS. labelled with the words 'Black Earth' or similar, because it is clearly a text of herbal alchemy, or more accurately proto-Paracelsean, and does not seem to belong in that other stream of European alchemical thinking.
