3. Terra Preta
Dark Earth
Amazonian Dark Earths
"Terra Preta de Indio"
Indian Black Earth is the local name for certain
dark earths in the Brazilian Amazon region.
Unknown methods of biochar production where
utilized via pyrolysis in the forest: some form of
“sustainable” slash and char developed huge areas
for food production.
These dark earths occur in several countries in
South America and Europe and Eastern USA. In
the Amazon it was created by pre-Columbian
Indians from 500 to 2500 years B.P. and
abandoned after the invasion of Europeans.
4. 1658 Johann Rudolf Glauber confirmed that the acid contained in pyroligneous water was the same
acid contained in vinegar (Emrich, 1985; Klark, 1925).
1661 The separation of a spirituous liquid from volatile products of wood distillation was described
by Robert Boyle (Klark, 1925).
8. LIGNIN
The complex amorphous organic component of
wood that acts as the binder between cells and
is responsible for its rigidity. It decomposes very
slowly by microbial action.
9. Wood that has been seasoned for 9-12 months still contains about 20-25% moisture, most of which is
wood resins. These resins play an important part in the three stages of wood combustion.

Stage 1 - the kindling fire warms up the fresh load of wood and any remaining water content is
removed by evaporation and vaporization.

11. Wood that has been seasoned for 9-12 months still contains about 20-25% moisture, most of which is
wood resins. These resins play an important part in the three stages of wood combustion.
Stage 1 - the kindling fire warms up the fresh load of wood and any remaining water content is
removed by evaporation and vaporization.
Stage 2 - As the wood reaches 500 degrees the resins begin to break down chemically, and volatile
gases are released which squirt out through the wood fiber and ignite, boosting the temperature of the
fire to around 1,100 degrees and producing 50-60% of the heat value from that load of wood.

14. If your firewood has dried to the point where it has lost its resin content, your
fire will go directly from Stage 1 (warming up to combustion temperature) to
Stage 3 (charcoaling), skipping Stage 2 and missing out on 50-60% of the heat
(and burn time) you'd expect to get from that load of wood

16. Pyrolysis is a thermochemical
decomposition of organic material
at elevated temperatures in the
absence of oxygen. It involves the
simultaneous change of chemical
composition and physical phase,
and is irreversible. The word is
coined from the Greek-derived
elements pyro "fire" and lysis
"separating".

17. 1792 England commercialized luminating gas manufactured from wood (Klark, 1925). 1812 Taylor
showed that methyl alcohol was present in the liquid obtained from the
distillation of pyroligneous water (Klark, 1925).
1819 The first pyrolysis oven to transfer heat through its metal walls was designed by
Carl Reichenbach (Klark, 1925).

20. 1835 Methyl alcohol, an isolated product of crude wood spirit, was discovered by Jean
Baptiste Andre Dumas and Eugene Peligot which confirmed Taylor’s ideas on the nature of
pyroligneous acid (Klark, 1925).
1850 Horizontal retorts (1 meter diameter, and 3 meters long) were used mainly by Germany,
England, and Austria, while the French were becoming more inclined to the use of vertical retorts
made portable by Robiquete (Klark, 1925).
1856 An increase in demand for methyl alcohol was a result of Sr. William H. Perkin’s patent on
aniline purple (Klark, 1925).
1864 The discovery of iodine increased the demand for wood spirits (Klark, 1925). 1870 Early
investigations performed by Tobias Lowitz resulted in a new, chemically
pure acetic acid (Klark, 1925).

Charcoal Dust As A Fertilizer. Charcoal is composed almost
entirely of pure carbon; and when small fragments are exposed
to the influences of the weather, they undergo very little change
during a long term of years. Still the roots of growing plants will
lay hold of the small pieces of charcoal, and appropriate the
substance contained in the coal to the growth and development
of the stems, leaves, and seeds of grain, fruit, and vegetables.
Experienced chemists assure us, charcoal, and particularly
charcoal dust, has the power of attracting and fixing large
quantities of ammonia, a substance which enters largely into the
formation of useful plants, and of retaining this fertilizing material
when buried in the soil, until the fine fibres of the roots of growing
plants require it for promoting their growth.

22. 1870 The rise of the celluloid industry and the manufacture of smokeless powder
increased the demand for acetone (Klark, 1925).
1880 The wood distillation industry began to expand (Klark, 1925).
1920-1950 The rise of the petroleum industry caused a decline in wood distillation (Klark,
1925).
1970 Oil Crisis gave rise to the need for alternative liquid fuels.
1970-90s Development of new pyrolysis reactors occurred side by side with the
understanding of the fundamentals of biomass pyrolysis reactions (Boroson et al., Bridgwater et al.,
1994; 1989 a, b; Evans et al., 1987 a, b; Mottocks, 1981, Piskortz et al., 1988a, b; Scott et al.,
1984, 1988).
23. Thai Charcoal Kiln
Charcoal As A Manure 1860………..
Liebig gives the results of a series of experiments by Lukas on
the use of charcoal as a manure, which seem to corroborate his
opinion. From the facts which these chemists, however, adduce,
it is evident that the beneficial action of charcoal, as a fertilizer,
depends upon the presence of other substances besides carbon.
Liebig notes (Organic Chem., p. 62) that “plants thrive in
powdered charcoal, and may be brought to blossom, and bear
fruit, if exposed to the influence of the rain and the atmosphere.
Plants do no not, however, attain maturity under ordinary
circumstances in charcoal powder when they are moistened with
pure distilled water instead of rain or river water. Rain water
must, therefore, contain within it one of the essentials of
vegetable life; and it has been shown that this is the presence of
a compound containing nitrogen; the exclusion of which entirely
deprives humus and charcoal of their influence on vegetation. It
is ammonia, to

how the qochas were linked to one another, through
an extensive network of canals. Twin circles are

1. Typically, the ability of soils to retain cations
in an exchangeable and thus plant-available
form (cation exchange capacity [CEC])
increases in proportion to the amount of soil
organic matter
• Biochar has an even greater ability
than other soil organic matter to adsorb
cations per unit carbon due to its
greater surface area,
• greater negative surface charge
• greater charge density
2. Biochar appears to be able to strongly
adsorb phosphate, even though it is an
anion, although the mechanism for this
process is not fully understood.
3. These properties make biochar a unique
substance, retaining exchangeable and
therefore plant-available nutrients in the soil,
and offering the possibility of improving crop
yields while decreasing environmental
pollution by nutrients considerably
