Therefore, in most of lands over volcanic ashes, transmuted fertile soils are found out.
In some regions, completely barren lands could be changed into even jungle-covered lands.
We think that such cases are originated in effective fertilizer-ingredients issued from volcanic ashes under weathering-metamorphosing processes.
It seems that features of transmuted volcanic ashes remarkably depend on each climate proper to individual region, compositions and characters of fallen volcanic ashes, its fertilizing-effects also have diverse aspects.
At present, we don't know about conditions and actions to transmute some volcanic ash into an other material and how to bring fertilizing effects to the land in detail ( in 2009 ).
