If you can "charge" biochar, then why not do something similar with the ramial chipped wood? I know they are functionally somewhat different, but it seems reasonable that the RCW could be soaked or otherwise treated to prevent the N leaching so commonly associated with burying them. I'm just high and throwing out ideas.
The discussion has been interesting so far.
It seems that bio-char works best in soils that are already low in nutrient holding capacity or have been leached via water or other degradation routes.
The difference is the 'active' stage of lignin and cellulose and the degradation process. When you char (partially combust) wood you alter the molecular structure (? as I understand [AIU]) of the lignin and cellulose to a stable form.
AIU the charging process is basically a precaution against the dreaded N lock out. The charging, obviously is not longterm, as the nutrients soaked up don't last perpetually as the char is intended to be used. The reason I first began soaking our char for a short duration in ACT was in following with my own hypothesis.
This was thought about after studying information on the Terra Preta areas in South America. (see below)
I figured that the char works in concert with microbial consortia.
Anyway if one wanted to use Ramial wood clippings in a similar fashion, they must first, similarly be stabilized. One could possibly accomplish this by aging/composting the clippings. This is actually practiced to create wood/bark fines to mix into growing media.
Once stabilized through aging/composting one could charge the clippings using your preferred substance and method.
OR
One could char the Ramial clippings
AIU one can topdress with Ramial clippings where surface oxygen and nitrogen are available to the microorganisms to transform RWC into humus and soil >> to be once again topdressed as time ensues, etc.
And one can work biochar (charged char) into the soil as a nutrient clingon.
read at your own risk;
It seems the current theory supports that this type of soil sustains carbons and nutrients over extended periods of time partially due to incompletely combusted organic materials (charcoal) and the interaction thereof with the soil microorganisms. The natives who
still have some bond to the history of this, maintain that if a minimum of 20 CM of the soil remains undisturbed by horticultural activities that the organismic activity re-sustains (re-invents) itself. This is not unlike a Winogradsky column which may provide a rudimentary laboratory example of what may be occurring here.
When one observes a map of the Terra Petra plots in the Amazon it is evident that there is a large concentration of them in close proximity to the larger trunks of the Amazon River and to the sea coast portion of the Amazon.
I also read that the indigenous people (IP) had built canals lined with special shaped (diamond) stones which allowed the flow of river silt. Now, knowing (or think I know {TIK}) that there are certain organisms (purple non sulfur bacteria,(PNSB) cyanobacteria, bacillus {N fixers}, yeast/fungi, protozoa, etc. etc.) in pond/river mud and in sea water and knowing (TIK) that sea water also contains a similar consortia of microbes (which may interact beneficially with the mud and forest microbes to create a broader spectrum consortia) and that there are large influxes of salt water up the Amazon; I may hypothesize that the IP flooded large paddies (beds, plots) with this silt/mud salt-fresh water mix. In these paddies were large amounts of incompletely combusted organic material (charcoal) remaining from the IP's method of clearing land. The result perhaps was the utilization of the charcoal by the microbe consortia to sustain itself and produce waste which resulted in the production and fixation of bio-available soil/plant nutrients. The organisms would naturally sustain themselves at the depths conducive to their aerobic/anaerobic and dietary lot in life, with fermentation occurring at the lower levels providing nutrients for the organisms above them. The phototrophic microbes (PNSBs; Rhodopseudomonas palustris, Rhodobacter sphaeriodes, Rhodobacter capsulatus; would naturally be somewhat closer to the surface to absorb light but not too close to hit air and the upper levels would consist of aerobic and facultative organisms (cyanobacteria, etc. if I'm not mistaken). This would support the statement that the system re-establishes itself if no more than 20 cm is disturbed. This is not unlike the theory behind EM use horticulturally and what we see in a healthy old growth forest and natural plains grass expanse.
Of course at some point the paddy/plot would be drained in preparation for planting but the microbial consortia presumably sustains itself with less moisture.
