last year, I visited the Ingelia THC continuous run installation in
Valencia/Spain.
They decompose 1t/h no matter what carbonous biomass into carbon in a
low temperature , hidric process at around 200°C and 20 bars pressure.
The result is a fine carbon rest of 50 -70 % and most of the other
elements of the original biomass stay in the process water, which is
very sour.
Are there any experiences among the listers with THC remainders in
agriculture?

Hi Frans, good to see your contribution.

Basic soil needs humus to bring pH 8,5 to 6,5
This is because humus (humic acid?) is acidic but so will low
temperature char that still contains pyroligneous chemicals??
Basic soil by Ca exess has lack of Mg take up to form Chlorofil leef green
.Result yellow leaves .
Ye Ca inhibits take up of magnesium, we have it once roots reach the
chalk on thin soils here, it's known as lime induced chlorosis.
Char has no chemical effect .
The carbon in char is inert but presumably its the ash associated with
the carbon matrix that makes high temperature char basic.
Sometimes water and minerals into the char are usefull at pH 5,5 -7.
Could you expand on that?
Basic soil makes trace minerals unsoluble and not avaiable to take up .
Zn and Se can profit of basic soil .
Too acid under pH 5 dissoves Aluminium from clay ,a plant killer .
I take from that that if the soil becomes too acid the aluminium
becomes labile and available, hence it kills the plants.
So similarly if the soil is too basic it makes zinc and selenium
unavailable?
