[Terrapreta] Chacoal soaked in sea water

Hi David,
I understand the value of sea minerals for plants. Could soaking fresh charcoal in sea water add too much salt and raise the pH even more, making already alkaline charcoal more alkaline with the Sodium-Na+ ions? As I understand soil inundated in seawater is too alkaline to have an effective CEC or to grow plants in well. Can you do something to seawater used in charcoal to change that? Or will you only dilute the salty charcoal in a large amount of soil?
Regards,
SKB

i am encouraged by the imagery of hot steam forcing water vapors deep into
the dense networks of micropores in charcoal. a steam treatment should
rapidly reduce char's initial resistance to absorbing water. might even
induce a few explosions and ruptures to the cellular celluose matrix of
micropores -- ripping open larger channels for macroscopic lifeforms to join
the community.
and since i'm most certainly making my char for soil enhancement, i
definitely intend to quench my first 2008 batch of hot char with sea water.
not just water, but sea water, to inject a full spectrum mineral solution
into the char, and thus improve its potential as microbial habitat. the
sooner microbes find water and a full menu of minerals, the sooner they will
take up residence in the char.
for a green & peaceful planet,
