[Terrapreta] volatile matter and char

TKS FOR COMMENTS
 
Complex inputs'......Char alone is not sufficient to make soil condition
increase . Combination with fertilizer and compost is right on track.
 
There is a need for addon nutrients plant  needed, increase soil organic
matter, and all together create optimal condition for soil microbio life.

Yes - A key point Ogawa made at the 2002 UGA meeting was a description of 
his study of Azotobacter distribution and activity with latitude and his
graphic showed EU to Japan.(Both less numerous and slower metabolism for
this free living nitrogen fixer). In my discussion with him about my planned
research at the farm he suggested treating the charcoal with some amount of
fertilizer and/or compost and to 'let it sit for a while' A woman from
Cornell at the meeting whose name I lost also recommended the same charcoal
preparation. I was never sure what he meant about this and why. But Larry's
results point out the need to do this --- or to wait for a few years for the
effects to show up. 


I only did this in 2002 for a few days and in 2006 put down untreated
charcoal on my block treatment study.



I am preparing the images of Larry's charcoal aging and treatment test and
will post later today but for the moment I would like to ask you if you have
suggestions for a 3 month pretreatment of charcoal , about 3000 lbs we
intend to spread on about 60,000 square feet of low organic matter sandy
soil we are preparing for cropping. An equal area will be left untreated. 


We do not know yet if it will be cover cropped and fall planted to crop or
planted immediately. I have become interested because of the shift in CEC of
our charcoal treated section that had been cropped for 4 years. 


This would be an opportunity to establish a block treatment 


Also Edward can you elaborate on what you mean by' rather complex inputs'

Lastly, distracted by this interesting topic this morning I pyrolysed my
oatmeal. It my wind up in my garden pot and all. :>()

Dr. Ogawa's view is correct, but need to be added, that the TP effect is
highly depending on soil and climate conditions. There is a difference in
effects in warmer climate than continental. Another issue is that in high
productive agriculture not only one parameter is considered, but rather 
complex inputs.

I keep going back to Dr. Ogawa's view that charcoal in the soil is a
selective enrichment for beneficial organisms in that it excludes
saprophytic organisms (ie no fermentable carbon source) and  otherwise
improves soils much like organic matter. In the context of volatile matter
here is the vm he cited on charcoal he claims has the following effects

Charcoal Characteristics and Uses Characteristics and Function of Charcoal
From: Makoto Ogawa, Effects of Soil Microbial Fertility by Charcoal in Soil
1.Porous substance with high water and air holding capacity; Suitable
habitat for some microbes and plant growth, good material for soil amendment
 absorption of chemicals and humidity control
2.High alkalinity; Neutralization of acidic soil and improvement of chemical
components of soil and selection of microorganisms
3.Non organic matter ; Exclusion of saprophytes and propagation of
autotrophic and symbiotic microorganisms, free living nitrogen fixing
bacteria, root nodule bacteria, Frankia and some mycorrhizal fungi
4.Low mineral content ; “Charcoal has no role as a fertilizer”
Composition of bark charcoal %
Carbon:77.58,
Volatile matter:12.92,
Ash: 9.50
Mineral content of ash %
SiO2:36.5
Al2O3:10.9
CaO:19.2
K2O:1.1
Na2O3:5.35
Fe2O3:7.5
MgO:10.3
P2O5:1.7
# Air supply by charcoal induces the activation of soil microbes and CO2
emission temporally. Small amounts of chemical fertilizers or organic matter
should be mixed with charcoal in agricultural use.
soil application of charcoal to provide a microhabitat for AM fungi to
colonize and survive.
